Description
Известен способ получени хлорангидридов алкилсерных кислот пзтем воздействи хлорсульфоновой кислоты на сложный эфир.A known method for the preparation of alkyl sulfuric acid chlorides is based on the effect of chlorosulfonic acid on the ester.
Описываемый способ в отличие от известного позвол ет получить продукт высокой степени чистоты при высоком его выходе. В этих цел х, в качестве сложного эфира используют борный эфир.The described method, in contrast to the known one, allows one to obtain a product of high purity with a high yield. For these purposes, boric ester is used as the ester.
Реакцию можно проводить в присутствии нейтрального органического растворител , если бор-нокислые эфиры представл ют собой кристаллические вещества, или в отсутствии растворител .The reaction can be carried out in the presence of a neutral organic solvent, if the boron esters are crystalline substances, or in the absence of a solvent.
Пример. К 115 г трибутилбората при тем пературе -10° и не выше +5° при размешивании механической мешалкой прибавл ют малыми порци ми 175 г хлорсульфоновой кислоты. Перемешивание продолжают после внесени последней порции хлорсзльфоновой кислоты при обычной комнатной температуре с последующим нагреванием в конце реакции на вод ной бане до 60° в течение 15 мин., затем борную кислоту отдел ют.Example. To 115 g of tributylborate at a temperature of -10 ° and not higher than + 5 °, while stirring with a mechanical stirrer, 175 g of chlorosulfonic acid are added in small portions. Stirring is continued after the last portion of chlorosclonic acid is added at ordinary room temperature, followed by heating at the end of the reaction in a water bath to 60 ° for 15 minutes, then the boric acid is separated.
Получают хлорангидрид бутилсерной кислоты в количестве 230 г со степенью чистоты 98,5%.Get the acid chloride butyl sulfuric acid in the amount of 230 g with a purity of 98.5%.
