Description
(54) СПОСОБ ПОЛУЧЕНИЯ М,3.3-ТЕТРАМЕТИЛ1 ,3-ДИСИЛОКСАНДИОЛА(54) METHOD OF OBTAINING M, 3.3-TETRAMETHYL1, 3-DISYLOXANDIOL
дела силанолы, хорошо раствор ющиес в воде , самопроизвольно вывод тс из сферы реакции , что преп тствзет образованию побочных длминоцепных диолов и циклосклоксаиов.Cases of silanols, which are well soluble in water, are spontaneously removed from the scope of the reaction, which prevents the formation of side dynolonechol diols and cyclocloxoxy.
Дисол выдел ют из реакционной смеси высаливанием с последующей перекристаллизацией из оргаиических растворителей.Disol is isolated from the reaction mixture by salting out, followed by recrystallization from organic solvents.
.Пример. В трехгорлую колбу с мешалкой , термометром и капельной воронкой помещают 600 мл дистиллированной ЕОДЫ и 30 г бикарбоната аммони , в течение I час при интенсивном перемешивании и О-5° С прикапывают 85,5 г (0,66 моль} диметилдихлорсилана в смеси с 96,8 г продуктов его аммонолиза и 20 мл бензина, перемешивают 10 мин, отдел ют бензиновый слой, из водного сло высаливают ДИСОЛ, который перекристаллизовы14С г (88,5%).Example. 600 ml of distilled EODA and 30 g of ammonium bicarbonate are placed in a three-necked flask with a stirrer, a thermometer and an addition funnel, and 85.5 g (0.66 mol) of dimethyldichlorosilane mixed with 96 , 8 g of its ammonolysis products and 20 ml of gasoline are mixed for 10 minutes, the gasoline layer is separated, DISOL is salted out of the aqueous layer, which are recrystallized 14 C g (88.5%)
зают из бензина. Получают продукта, т. пл. 61-62° С. - Найдено, %: ОН 20,07. Вычислено, %: ОН 20,44.zayut of gasoline. Get the product, so pl. 61-62 ° C. - Found,%: OH 20.07. Calculated,%: OH 20.44.
