Description

Otrzymywane dzialaniem kwasu siar¬ kowego na nienasycone wyzsze kwasy tluszczowe kwasy sulfonowe saf jak wia¬ domo, malo odporne na dzialanie kwasów, gdyz ich wodne roztwory juz w obecno¬ sci nieznacznej ilosci kwasu mineralnego przy ogrzewaniu metnieja, wydzielajac po krótkim czasie kropelkji oleju, Stosujac wysokoprocentowe oleum (66%) udaje sie wprawdzie zwiekszyc kwasoodpornosc, wymaga to jednak, wskutek gwaltownosci reakcji i trudnosci zwiazanych z równo- miernem mieszaniem, dodania znacznych ilosci obojetnego srodka rozcienczajace¬ go, który pózniej nalezy usunac.Okazalo sie, ze produkt odporny na dzialanie kwasu mozna otrzymac w sposób prostszy i zapomoca slabszego oleum, sko¬ ro sulfonowac mieszanine z kwasów tlu¬ szczowych i fenoli.Dodanie fenoli ma te zalete, iz masa staje sie plynniejsza, wskutek czego moz¬ na ja mieszac i ochladzac równomiernie do zakonczenia sulfonowania.Oprócz nadzwyczajnej odpornosci na dzialanie kwasów rzeczone oleje sulfono¬ wane posiadaja nawet w temperaturze zwyklej bardzo dobra zdolnosc zwilzania welny lub bawelny. Zdolnosc zwilzania o charakterze podobnym do oleju tureckiego pozwala stosowac produkty rzeczone do wielu celów w przemysle wlókienniczym.Moga one sluzyc do zarabiania barwników kadziowych i do barwienia niemi, do bar¬ wienia zapomoca barwników siarkowych, zapobiegajac przebarwieniu zwanemu,,bronzowaniem'\ ponadto moga sluzyc do emulgowania nierozpuszczalnych w wodzie weglowodorów, weglowodorów chlorowa¬ nych i zwiazków uwodornionych, jako do¬ mieszka do kleju tkackiego i t. d. Nadaja sie one szczególnie do kwasnego barwienia welny, egalizujac trudnoegalizujace barw¬ niki i pozwalajac tym ostatnim przeniknac wglab, dzieki czemu mozna barwic rów¬ niez grube materjaly, scisle sprasowane.Przyklad. Do roztworu, zawierajacego 12 czesci wagowych fenolu i 30 czesci wa¬ gowych technicznego kwasu olejowego, wkrapla sie powoli, ochladzajac bardzo starannie, w temperaturze 10—15° 45 czesci wagowych 20% -ego oleum, poczem w tem¬ peraturze tej pozostawia sie w spokoju do nastepnego dnia. Nastepnie mieszanine reakcyjna rozciencza sie w 100 cz. wag. lodu, oddziela od wydzielonego wodnistego kwasu siarkowego, przemywa nasyconym roztworem soli kuchennej, zobojetnia lu¬ giem sodowym i odparowuje sie do otrzy¬ mania syropu.Otrzymuje sie mase lepka, podobna do oleju tureckiego, która rozpuszcza sie z latwoscia w wodzie. Roztwory wodne po kilkugodzinnem gotowaniu z rozcienczone- mi kwasami zachowuja calkowita przezro¬ czystosc. PL PLSulfonic acids, obtained by the action of sulfuric acid on higher unsaturated fatty acids, are known to be little resistant to the action of acids, because their aqueous solutions, even in the presence of a small amount of mineral acid, melt when heated, giving off oil droplets after a short time. Although high-percentage oleum (66%) manages to increase the acid resistance, it requires, due to the rapidity of the reaction and the difficulty of mixing evenly, the addition of a considerable amount of inert diluent, which must be removed later. The acid can be obtained more simply and with a weaker oleum, so that it is sulfonated with a mixture of fatty acids and phenols. The addition of phenols has the advantage that the mass becomes more fluid, so that it can be mixed and cooled uniformly until the sulfonation is complete. In addition to their extraordinary resistance to acids, these sulphonated oils even at temperatures usually very good wetting of wool or cotton. The wetting ability similar to Turkish oil allows the use of these products for many purposes in the textile industry. They can be used for making vat dyes and for dyeing with them, for dyeing with sulfur dyes, preventing discoloration called "bronzing", and can also be used for for the emulsification of water-insoluble hydrocarbons, chlorinated hydrocarbons and hydrogenated compounds as additives for weaving glue, and hence, they are particularly suitable for acid dyeing wool, equalizing difficult-to-legalize dyes and allowing the latter to penetrate into the water so that the ditch can be colored ¬ Not thick materials, tightly pressed. Example. To a solution containing 12 parts by weight of phenol and 30 parts by weight of technical oleic acid is slowly added dropwise, while cooling very carefully, at a temperature of 10-15 ° 45 parts by weight of 20% oleum, and then left at this temperature. peace until the next day. Then the reaction mixture is diluted in 100 parts. wt. The ice is separated from the separated aqueous sulfuric acid, washed with a saturated solution of common salt, neutralized with soda and evaporated to a syrup. A viscous mass, similar to Turkish oil, is obtained which dissolves easily in water. Aqueous solutions, after a few hours of cooking with diluted acids, remain completely transparent. PL PL
