Description
Foreliggende oppfinnelse vedrører syntetiske, krystallinskeThe present invention relates to synthetic, crystalline
og porøse materialer av zeolittnatur bestående av silisiumoksyd og boroksyd og som i deres vannfri tilstand tilsvarer følgende empiriske formel: and porous materials of a zeolite nature consisting of silicon oxide and boron oxide and which in their anhydrous state correspond to the following empirical formula:
hvori a varierer fra 0 til 1, x varierer fra 30 til 120, where a ranges from 0 to 1, x ranges from 30 to 120,
Me er et H+<->kation, eller et NH<*->kation eller et alkalimetall-kation, R er et eller flere tetraalkylammonium-kationer og det særegne ved de syntetiske materialer i henhold til oppfinnelsen er at de er fremstilt ved at man under hydrotermiske betingelser omsettes et silisiumderivat, et borderivat, en blanding av tetraalkylammonium- og tetrabutylammonium-.. hydroksyd eller som er alternativ en blandet kvaternær base av metylbutylammonium hydroksyd, eventuelt i nærvær av et alkalimetall-hydroksyd eller ammonium-hydroksyd, med et molart forhold forhold Si02:B2C>2 for reaksjonskomponentene valgt fra 0,5 til 30, et molart forhold for reaksjonskomponentene H20:Si02valgt fra 10 til 50, et molart forhold R:Si02av reaksjonskomponentene valgt mellom 0,0 5 og 5 og et molart forhold Me<+>:Si02for reaksjonskomponentene valgt mellom 0 og 0,5. Me is an H+<-> cation, or an NH<*-> cation or an alkali metal cation, R is one or more tetraalkylammonium cations and the distinctive feature of the synthetic materials according to the invention is that they are produced by under hydrothermal conditions, a silicon derivative, a boron derivative, a mixture of tetraalkylammonium and tetrabutylammonium hydroxide or alternatively a mixed quaternary base of methylbutylammonium hydroxide is reacted, possibly in the presence of an alkali metal hydroxide or ammonium hydroxide, with a molar ratio ratio Si02:B2C>2 for the reaction components selected from 0.5 to 30, a molar ratio for the reaction components H20:SiO2 selected from 10 to 50, a molar ratio R:SiO2 of the reaction components selected between 0.0 5 and 5 and a molar ratio Me< +>:Si02 for the reaction components chosen between 0 and 0.5.
Disse og andre trekk ved oppfinnelsen fremgår av pa tentkr avene.These and other features of the invention appear in the patent claims.
Det er tidligere kjent syntetiske materialer basert på silisiumoksyd og boroksyd. Previously known synthetic materials based on silicon oxide and boron oxide.
I belgisk patentskrift 877.205 omhandles fire syntetiske materialer bestående av silisiumoksyd og boroksyd med en krystallinske og porøs struktur, deres fremstillingsmåte og deres anvendelse. Belgian patent document 877,205 deals with four synthetic materials consisting of silicon oxide and boron oxide with a crystalline and porous structure, their method of production and their use.
Disse materialer som benevnes "Boralite A", "Boralite B", "Boralite C", "Boralite D" er blitt syntetisert ved hjelp av organiske substanser tilstede, foretrukket tetraalkylammonium-ioner, som har den virkning at de fører til syntese i retning av den ønskede struktur. These materials named "Boralite A", "Boralite B", "Boralite C", "Boralite D" have been synthesized by means of organic substances present, preferably tetraalkylammonium ions, which have the effect of leading to synthesis in the direction of the desired structure.
Disse kationer er tetrametylammonium for "Boralite A", tetraetylammonium for "Boralite B", tetraetylammonium eller tetrapropylammonium eller et kation avledet fra etylendiamin for "Boralite C", og tetrabutylammonium for "Boralite D". These cations are tetramethylammonium for "Boralite A", tetraethylammonium for "Boralite B", tetraethylammonium or tetrapropylammonium or a cation derived from ethylenediamine for "Boralite C", and tetrabutylammonium for "Boralite D".
Det er overraskende funnet en ny boralitefamilie som her benevnes "Boralite E", fremstilt ved at man for syntesen anvender en blanding av tetraalkylammoniumbaser eller blandede tetraalkylammoniumbaser. A new boralite family has surprisingly been found, which is here named "Boralite E", produced by using a mixture of tetraalkylammonium bases or mixed tetraalkylammonium bases for the synthesis.
Ammoniumbasene som anvendes for oppnåelse av "Boralite E" The ammonium bases used to obtain "Boralite E"
er blandinger av tetrametyl- og tetrabutylammonium-hydroksyd i forskjellige mengdeforhold, eller blandede baser som tributylmetylammonium-hydroksyd, dimetyldibutylammonium-hydroksyd og butyltrimetylammonium-hydroksyd. are mixtures of tetramethyl- and tetrabutylammonium hydroxide in different proportions, or mixed bases such as tributylmethylammonium hydroxide, dimethyldibutylammonium hydroxide and butyltrimethylammonium hydroxide.
Boralitene av "E" familien kan i deres vannfri tilstand be-tegnes på basis av molare forhold av oksydene, ved hjelp av følgende formel: The boralites of the "E" family can be designated in their anhydrous state on the basis of molar ratios of the oxides, using the following formula:
hvori a har en verdi mellom 0 og 1, x har en verdi mellom 30 og 120, R er det eller de kvaternære ammonium-kationer som er nevnt ovenfor, Me er et kation som H+, eller NH<+>^eller et alkalimetallion. wherein a has a value between 0 and 1, x has a value between 30 and 120, R is the quaternary ammonium cation(s) mentioned above, Me is a cation such as H+, or NH<+>^ or an alkali metal ion.
De syntetiske materialer i samsvar med oppfinnelsen er krystallinske ved røntgenanalyse. Denne analyse gjennomføres ved hjelp av et diffraktometer av den type som er egnet for pulveret og utstyrt med en elektronisk pulstellerinnretning idet CuK -stråling anvendes. For beregning av intensitetene er høyden av toppene blitt målt og angitt på basis av prosentandel i forhold til høyden av den mest intense topp. The synthetic materials according to the invention are crystalline by X-ray analysis. This analysis is carried out using a diffractometer of the type suitable for the powder and equipped with an electronic pulse counter device, using CuK radiation. For calculating the intensities, the height of the peaks has been measured and indicated on the basis of a percentage in relation to the height of the most intense peak.
Røntgen-diffraksjons-spektrane av "Boralite E" er tilsvarende som for "Boralite C" så langt som verdiene for interplanar-avstandene, d, men vesentlige variasjoner opptrer i intensi-tetforholdene i sammenlikning med "Boralite C". Mer spesielt kan de bemerkes for spekteret for "Boralite E" at intensiteten av et visst antall av typiske refleksjoner av "Boralite C" er nedsatt i forhold til andre, som bibeholder deres karak-teristiske intensiteter. Ingen prøve av "Boralite E" viser en total forsvinning av slike refleksjoner. The X-ray diffraction spectra of "Boralite E" are similar to those of "Boralite C" as far as the values for the interplanar distances, d, but significant variations appear in the intensity ratios compared to "Boralite C". More particularly, it can be noted for the spectrum of "Boralite E" that the intensity of a certain number of typical reflections of "Boralite C" is reduced in relation to others, which retain their characteristic intensities. No sample of "Boralite E" shows a total disappearance of such reflections.
Nettopp på grunn av variasjonen i røntgen-diffraksjons spektrane tales det om en familie av "Boralite" snarere enn en eneste forbindelse. Precisely because of the variation in the X-ray diffraction spectra, it is spoken of as a family of "Boralite" rather than a single compound.
De vesentlige refleksjoner som opptrer i det nevnte forhold erkarakterisert vedfølgende verdier for d, nemlig: The significant reflections that occur in the aforementioned relationship are characterized by the following values for d, namely:
For å gi en kvantitativ ide av forholdet er det valgt forholdet mellom intensiteten ved refleksjonen ved ;- In order to give a quantitative idea of the relationship, the ratio between the intensity of the reflection at ;-
d = 3.63 + 0.05 Å (I ) i forhold til refleksjonen med ikke-variant intensitet ved d = 3.83+ 0.05 Å (I2). I "Boralite C" er forholdet 1^til I2typisk nok nær 0,40. I "Boralite E" er dette forhold nedsatt og kan falle til verdier på om-trent 0.1. d = 3.63 + 0.05 Å (I ) compared to the reflection with non-variant intensity at d = 3.83 + 0.05 Å (I2). In "Boralite C" the ratio 1^ to I 2 is typically close to 0.40. In "Boralite E", this ratio is reduced and can fall to values of approximately 0.1.
I hvilket som helst individuelt "Boralite E" er intensitets nedsettelsen liknende, på basis av prosentangivelse, for alle de nevnte refleksjoner, mens størrelsen av fenomenet varierer fra et hvilket som helst produkt til et annet. In any individual "Boralite E", the intensity reduction is similar, on a percentage basis, for all of the aforementioned reflections, while the magnitude of the phenomenon varies from any one product to another.
Tabell 1 gjengir en sammenlikning mellom røntgen-diffrak-sjonsspektra av et "Boralite E" (som oppnådd ved metoden i eksempel 4 i det følgende) og det tilsvarende spektrum av et typisk "Boralite C" (som fremstilt i henhold til belgisk patentskrift 877.205). Begge spektra vedrører produktet i H+-formen, d.v.s. produkter som er blitt kalsinert i 6 timer ved 550°C, ionebyttet med ammoniumacetat og kalsinert på nytt ved 550°C i 6 timer. Table 1 reproduces a comparison between the X-ray diffraction spectra of a "Boralite E" (as obtained by the method in Example 4 below) and the corresponding spectrum of a typical "Boralite C" (as prepared according to Belgian patent document 877,205) . Both spectra relate to the product in the H+ form, i.e. products that have been calcined for 6 hours at 550°C, ion-exchanged with ammonium acetate and calcined again at 550°C for 6 hours.
Mindre variasjoner i spekteret i tabell 1 kan skrive seg fra variasjoner i Si/B forholdet, kalsineringstemperaturen eller nærværet av kationer. Fremgangsmåten for fremstilling av "Boralite E" omfatter trinnet med at man under hydrotermiske betingelser reagerer et silisiumderivat, et borderivat, en blanding av tetrametyll-ammonium- og tetrabutylammonium-hydroksyd under bestemte mengdeforhold, eller som er alternativ, en blandet kvaternær base av metylbutylammonium-hydroksyd som definert i det Smaller variations in the spectrum in table 1 can result from variations in the Si/B ratio, the calcination temperature or the presence of cations. The process for the production of "Boralite E" comprises the step of reacting under hydrothermal conditions a silicon derivative, a boron derivative, a mixture of tetramethylammonium and tetrabutylammonium hydroxide under certain quantity conditions, or alternatively, a mixed quaternary base of methylbutylammonium hydroxide as defined therein
