Abstract

Способ разделения исходной смеси, содержащей, по меньшей мере, один ароматический углеводород и, по меньшей мере, один неароматический углеводород, экстрактивной дистилляцией (ЭД) с использованием смеси растворителей, включающей сульфолан и, по меньшей мере, один сорастворитель. Сорастворитель представляет собой алкилсульфон, содержащий от 4 до 8 атомов углерода в молекуле. Смесь растворителей добавляют в верхнюю часть колонны ЭД, а исходную смесь в точке на колонне ЭД, которая расположена ниже, чем точка, в которую вводится смесь растворителей. Протекает экстрактивная дистилляция, и ароматические и неароматические углеводороды разделяются.Отчет о международном поиске был опубликован 2002.03.14.
