Description
Foreliggende oppfinnelse angår fremstilling av hydroksyalkensyrer fra de tilsvarende to-formylalkensyrer. The present invention relates to the production of hydroxyalkenic acids from the corresponding two-formylalkenic acids.
Ifølge norsk patent nr (søknad nr. 742487) fremstilles umettede lineære polyfunksjonelle og rettkjedede syrer, f. eks. to-f ormylalkensyrer, fra polyumettede cykloolefi-ner ved selektiv osonisering. Denne prosess er ny og åpner store muligheter for industriell utnyttelse. According to Norwegian patent no. (application no. 742487), unsaturated linear polyfunctional and straight-chain acids are produced, e.g. toformylalkenic acids, from polyunsaturated cycloolefins by selective ozonization. This process is new and opens up great opportunities for industrial exploitation.
Ifølge foreliggende oppfinnelse fremstilles således u-hydroksyalkensyrer ved at den tilsvarende to-formylalkensyre ■ behandles for selektiv reduksjon av formylgruppen. Ifølge et annet trekk ved oppfinnelsen blir oo-hydroksyalkensyrene forest-ret for dannelse av de tilsvarende umettede estere. According to the present invention, u-hydroxyalkenic acids are thus prepared by treating the corresponding to-formylalkenic acid ■ for selective reduction of the formyl group. According to another feature of the invention, the o-hydroxyalkenic acids are esterified to form the corresponding unsaturated esters.
Ved å velge to-f ormylalkensyrer med forskjellige kjedelengder, grad av umettethet og besittelse av dobbeltbindinger, som mellomprodukter, d.v.s. utgangsmaterialer, for foreliggende fremgangsmåte, kan de tilsvarende forskjellige to-hydroksyalkensyrer fremstilles . By choosing two-formyl alkenoic acids with different chain lengths, degree of unsaturation and possession of double bonds, as intermediates, i.e. starting materials, for the present method, the corresponding different two-hydroxyalkenic acids can be prepared.
Fremgangsmåten ifølge foreliggende oppfinnelse kan f.eks. utføres som følger: Det umettede syrealdehyd oppløses i et oppløsningsmiddelsystem omfattende vann og et vannblandbart organisk oppløsningsmiddel, og den således oppnådde oppløsning underkastes, eventuelt etter nøytralisering med en egnet alkali, selektiv reduksjon ved hjelp av et reduksjonsmiddel, som ikke reduserer dobbeltbindinger. Som vannblandbart organisk oppløs-ningsmiddel kan f.eks. anvendes en alkohol, tetrahydrofuran, dioksan, osv. Det organiske oppløsningsmiddel må naturligvis være inert med hensyn til både reduksjonsmidlet og de funksjo-nelle grupper i den umettede forbindelse. The method according to the present invention can e.g. is carried out as follows: The unsaturated acid aldehyde is dissolved in a solvent system comprising water and a water-miscible organic solvent, and the solution thus obtained is subjected, possibly after neutralization with a suitable alkali, to selective reduction by means of a reducing agent, which does not reduce double bonds. As a water-miscible organic solvent, e.g. an alcohol, tetrahydrofuran, dioxane, etc. is used. The organic solvent must of course be inert with regard to both the reducing agent and the functional groups in the unsaturated compound.
Som nøytraliseringsmiddel anvendes f.eks. en alkalisk forbindelse slik som natriumkarbonat. Som reduksjonsmiddel anvendes f.eks. natriumborjodid. Reduksjonen ved foreliggende fremgangsmåte utføres ved en temperatur på mellom -10°C og romtemperatur. Separeringen av den oppnådde hydroksysyre utføres ifølge konvensjonelle metoder, f.eks. ved inndampning av det organiske oppløsningsmiddel, surgjøring og ekstrahering med et egnet oppløsningsmiddel. As a neutralizing agent, e.g. an alkaline compound such as sodium carbonate. As a reducing agent, e.g. sodium boroiodide. The reduction in the present method is carried out at a temperature of between -10°C and room temperature. The separation of the obtained hydroxy acid is carried out according to conventional methods, e.g. by evaporation of the organic solvent, acidification and extraction with a suitable solvent.
Utgangsmaterialene som anvendes i foreliggende fremgangsmåte, nemlig o>-formylalkensyrer, fremstilles som beskrevet i norsk patent nr (søknad nr. 742487) 3 fra umettede og lett tilgjengelige polyolefiner slik som cyklooktadien og cyklododecatrien som kan ansees som rene produkter. Sett i forbindelse med den ovenfor nevnte fremstilling av utgangsmaterialer, vil de fremstilte hydroksyalkensyrer inneha samme renhetsgrad og produktvariasjon. Det er spesielt viktig ved fremstilling av utgangsmaterialer for foreliggende oppfinnelse at en eller flere dobbeltbindinger bibeholdes i disse utgangsmaterialer, idet^ man i denne forbindelse benytter seg av selektive osone-ringsmidler. The starting materials used in the present method, namely o>-formylalkenic acids, are prepared as described in Norwegian patent no (application no. 742487) 3 from unsaturated and easily available polyolefins such as cyclooctadiene and cyclododecatriene which can be considered as pure products. Seen in connection with the above-mentioned production of starting materials, the produced hydroxyalkenic acids will have the same degree of purity and product variation. It is particularly important in the production of starting materials for the present invention that one or more double bonds are retained in these starting materials, as selective ozonating agents are used in this connection.
De umettede produkter har viktige anvendelser som polymere eller som kopolymere hvis spesifikke og potensielle reaktivitet på grunn av dobbeltbindinger gjør dem i stand til viktige anvendelser for fremstilling av produkter som i sin tur er i besittelse av spesielle egenskaper, f.eks. tekstilprodukter som har en høy grad av fargebarhet, tilsatsstoffer for antista-tiske midler eller for harpikser og andre produkter, noe som klart vil fremgå for enhver som er kjent med den foreliggende teknikk. The unsaturated products have important applications as polymers or as copolymers whose specific and potential reactivity due to double bonds make them capable of important applications for the production of products which in turn possess special properties, e.g. textile products which have a high degree of dyeability, additives for antistatic agents or for resins and other products, which will be clear to anyone familiar with the present technique.
Under den detaljerte beskrivelse som følger, og i de forskjellige eksempler som illustrerer oppfinnelsen, er visse av disse produkter og deres mulige anvendelse angitt. During the detailed description that follows, and in the various examples illustrating the invention, certain of these products and their possible application are indicated.
Av andre nye umettede produkter som kan tilveiebringes ifølge oppfinnelsen, hvor den industrielle viktighet kan fast-slås og er lett tenkbar, kan nevnes 12-hydroksy-4,8-dodecadiensyre og 8-hydroksy-4-octensyre hvorfra der kan tilveiebringes umettede estere og/eller polyestere, og, henholdsvis, metylesteren av de ovennevnte syrer såvel som en serie biprodukter. Of other new unsaturated products that can be provided according to the invention, where the industrial importance can be established and is easily conceivable, mention can be made of 12-hydroxy-4,8-dodecadienoic acid and 8-hydroxy-4-octenoic acid from which unsaturated esters can be provided and /or polyesters, and, respectively, the methyl ester of the above-mentioned acids as well as a series of by-products.
Som en demonstrasjon på anvendeligheten av foreliggende oppfinnelse vil det heretter bli gitt en detaljert forklaring på fremgangsmåter som er eksempler på hvorledes man kan tilveiebringe nye produkter ifølge oppfinnelsen. Denne beskrivelse fullstendiggjøres ved de vedheftede tegninger, hvor: Fig. 1-3 gjengir et tilsvarende antall IR og NMR spektra for disse umettede forbindelser som tilveiebringes ifølge oppfinnelsen, nærmere bestemt: Fig. 1 gjengir IR spekteret for 11-formyl-t, t-4, 8-undecandiensyre, Fig. 2 gjengir IR-spekteret for 12-hydroksy-t, t-4, 8-dodecadiensyre tilgjengelig fra det umettede syrealdehyd hvis spektrum er vist i fig. 35Fig. 3 gjengir IR-spekteret for metylesteren av den nevnte hydroksysyre. As a demonstration of the applicability of the present invention, a detailed explanation will now be given of methods which are examples of how to provide new products according to the invention.

IA Omdanning av mono-osonid av t,t,t-CDT til 11-formyl-t,t-4, 8- undecadiensyre. IA Conversion of the mono-osonide of t,t,t-CDT to 11-formyl-t,t-4, 8- undecadienoic acid.
Omdannelsen av CDT mono-osonid til 11-formyl-t,t-4,8-undecadiensyre utføres katalytisk som beskrevet i det følgende eksempel. 11-formylundecansyre og aldehydsyren i de analoge serier (som har 8 og 10 karbonatomer) er viktige mellomstoffer for deres omdannelse til aminosyrer, hydroksysyrer, estere, f.eks. harpikser, etc. The conversion of CDT mono-osonide to 11-formyl-t,t-4,8-undecadienoic acid is carried out catalytically as described in the following example. 11-formylundecanoic acid and the aldehyde acid in the analogous series (which have 8 and 10 carbon atoms) are important intermediates for their conversion to amino acids, hydroxy acids, esters, e.g. resins, etc.
Osonidoppløsningen (1900 g/time) som kommer inn i apparatet sendes kontinuerlig inn på bunnen av det første omdanningsapparat som består av en stålsylinder med rom utstyrt med termometer, en rører av turbintypen og kappe for temperatur- regulering som holdes på 20°C. Omdanningsapparatet tilføres også kontinuerlig 4,75 g/time natriumacetat oppløst i 42,8 g eddiksyre. Blandingen som kommer ut på toppen av det første omdanningsapparat passerer til et annet omdanningsapparat som tilsvarer det første og som er temperaturregulert til 30°C. Begge omdanningsapparater holdes under en inert gassatmosfære (karbondioksyd). En slik oppholdstid er 7 timer og 30 min. Omrøringen er meget langsom. The ozonide solution (1900 g/hour) entering the apparatus is continuously fed into the bottom of the first conversion apparatus which consists of a steel cylinder with a chamber equipped with a thermometer, a turbine-type stirrer and jacket for temperature regulation which is maintained at 20°C. The conversion apparatus is also continuously supplied with 4.75 g/hour of sodium acetate dissolved in 42.8 g of acetic acid. The mixture that comes out at the top of the first conversion device passes to another conversion device corresponding to the first and which is temperature-regulated at 30°C. Both conversion devices are kept under an inert gas atmosphere (carbon dioxide). Such a residence time is 7 hours and 30 minutes. The stirring is very slow.
Hvis man setter prosentvis aktivt oksygen (oksygen som peroksyd) ved inngangen til det første omdanningsapparat til 100, vil analysen av denne variable ved utgangen av det første omdanningsapparat være 31,7 % og ved utgangen av det andre omdanningsapparat 7,6 % (omdanning 92,4 %). Oppløsningen som kommer ut av det annet omdanningsapparat sendes til en væske-filmfordamper for å fjerne oppløsningsmidlene. Resten, 526 g/ time, av en oljeaktig væske ved romtemperatur, behandles kontinuerlig ved 72°C med 526 g/time vann (oppholdstid i 60 min.) i en inert gass (nitrogen) atmosfære. "Vannet fordampes igjen som en væskefilm. Dette tilveiebringer 539 g/time av en oljeaktig rest som fremdeles inneholder små mengder vann, eddiksyre og parafinolje og som har følgende karakteristika: If one sets the percentage of active oxygen (oxygen as peroxide) at the entrance to the first converter to 100, the analysis of this variable at the output of the first converter will be 31.7% and at the output of the second converter 7.6% (conversion 92 .4%). The solution exiting the second converter is sent to a liquid film evaporator to remove the solvents. The remainder, 526 g/hour, of an oily liquid at room temperature, is treated continuously at 72°C with 526 g/hour of water (residence time 60 min.) in an inert gas (nitrogen) atmosphere. "The water is evaporated again as a liquid film. This provides 539 g/hour of an oily residue which still contains small amounts of water, acetic acid and paraffin oil and which has the following characteristics:

Enkeltderivater av omdanningsproduktet av CDT osonid som i seg selv er interessante og som i tillegg tjener til å etablere renheten i det tilveiebragte syrealdehyd, fremstilles i de følgende eksempler. Individual derivatives of the transformation product of CDT ozonide which are interesting in themselves and which additionally serve to establish the purity of the acid aldehyde provided, are prepared in the following examples.
50 g umettet syrealdehyd fremstilt ifølge eksempel IA (kokep. ved 3 mm Hg = l80-l83°C) tilføres en 1-liters glass-kolbe og under omrøring tilsettes 250 ml etylalkohol. Blandingen avkjøles ved 0°C hvoretter 19, 2 g natriumbikarbonat oppløst i 250 ml vann tilsettes. Etter at tilsatsen av natriumbikarbo-natoppløsningen er avsluttet plaseres apparaturen under vakuum og temperaturen holdes på 20-25°C 50 g of unsaturated acid aldehyde prepared according to example IA (boiling point at 3 mm Hg = 180-183°C) are added to a 1-liter glass flask and, while stirring, 250 ml of ethyl alcohol are added. The mixture is cooled at 0°C, after which 19.2 g of sodium bicarbonate dissolved in 250 ml of water are added. After the addition of the sodium bicarbonate solution is finished, the apparatus is placed under vacuum and the temperature is kept at 20-25°C
Etter at all karbondioksyd er utviklet, avkjøles blandingen igjen til 0°C og 7 g natriumborhydrid oppløst i 60 ml vann tilsettes langsomt. Oppløsningen hensettes i 1 time ved 0°C og deretter over natten ved romtemperatur. Oppløsningen fordampes til et lite volum under vakuum i en C02-strøm for å dekomponere hovedmengden av overskuddet av natriumborhydrid. After all the carbon dioxide has evolved, the mixture is cooled again to 0°C and 7 g of sodium borohydride dissolved in 60 ml of water is added slowly. The solution is left for 1 hour at 0°C and then overnight at room temperature. The solution is evaporated to a small volume under vacuum in a stream of CO 2 to decompose the bulk of the excess sodium borohydride.
Deretter tilsettes 50 ml en N/l NaOH og oppløsningen ekstraheres med eter hvoretter eterekstraktet fordampes til tørrhet. Dette gir en rest (2,2 g) som består av en blanding av cyklododecatrien og dodecadien-(4,8)-diol-(l,12). Then 50 ml of one N/l NaOH is added and the solution is extracted with ether, after which the ether extract is evaporated to dryness. This gives a residue (2.2 g) consisting of a mixture of cyclododecatriene and dodecadiene-(4,8)-diol-(1,12).
Vannfasen gjøres sur med saltsyre til pH 2 og ekstraheres igjen med eter. Ekstraktet vaskes med 30 ml vann, tørkes over magnesiumsulfat og fordampes til tørrhet. Resten består av 39,5 g 12-hydroksy-dodecan-t,t-4,8-diensyre som fremgår av følgende analyse: The water phase is made acidic with hydrochloric acid to pH 2 and extracted again with ether. The extract is washed with 30 ml of water, dried over magnesium sulphate and evaporated to dryness.
