METHOD FOR SEPARATING N-HEXANE AND 1-HEXENE FROM EACH OTHER BY USING IONIC LIQUID

Document Type and Number:

WIPO Patent Application WO/2023/090490

Kind Code:

A1

Abstract:

The present invention relates to a method for separating 1-hexene from n-hexane in a mixture of n-hexane and 1-hexene, which have similar physicochemical properties, by using an ionic liquid, and the method for separating n-hexane and 1-hexene from each other by using an ionic liquid, according to the present invention, comprises the steps of: 1) mixing a mixture of n-hexane and 1-hexene with an ionic liquid; 2) stirring the mixed solution and stabilizing same; and 3) separating 1-hexene from a bottom product.
