Abstract

Бензол в другие ароматические соединения выполняют из потока смешанных углеводородов, содержащих как ароматические, так и неароматические соединения, проведением экстрактивной дистилляции с использованием растворяющий системы, содержащей диметилсульфоксид и, что но является обязательным, совместный растворитель, желательно воду, после чего проводят дистилляционное отделение ароматических соединений от обогащенной растворяющей системы с возвратом обедненной растворяющей системы на стадию экстрактивной дистилляции.
