Description

Изобретение относитс  к области извлечени  ароматических углеводородов из смесей с неароматическими углеводородами.This invention relates to the field of extraction of aromatic hydrocarbons from mixtures with non-aromatic hydrocarbons.

Известен способ экстракции ароматических углеводородов с нрименением сульфолана в качестве селективного растворител  дл  выделени  ароматических углеводородов.A known method for the extraction of aromatic hydrocarbons with the use of sulfolane as a selective solvent for the separation of aromatic hydrocarbons.

Однако, применение сульфолана в качестве селективного растворител  не позвол ет проводить процесс экстракции с максимальной степенью извлечени  и высоким коэффициентом распределени .However, the use of sulfolane as a selective solvent does not allow for the extraction process with a maximum degree of extraction and a high distribution coefficient.

С целью повышени  степени извлечени  целевого продукта предлагают в качестве селективного растворител  примен ть а-тетрагидрофурфурил-р-оксипропионитрилIn order to increase the recovery rate of the target product, α-tetrahydrofurfuryl-p-oxypropionitrile is proposed as a selective solvent.
