Title:

A PROCESS OF REMOVING HEAVIER HYDROCARBONS FROM THE REACTION PRODUCTS OF PRODUCING SEC-BUTYL ACETATE

Document Type and Number:

WIPO Patent Application WO/2009/033381

Kind Code:

A1

Abstract:

Disclosed is a process of removing heavier hydrocarbons from the reaction products of producing sec-butyl acetate, which is characterized in: drawing out the materials from heavier hydrocarbon-rich zone and contacting the materials with water sufficiently, thereby the heavier hydrocarbons and water coming into layers naturally. The upper layer of heavier hydrocarbons is discharged and the lower layer of water is recharged into the system. The heavier hydrocarbon-rich zone refers to a zone enriched with heavier hydrocarbons and formed at the lower part of the azeotropic rectification column during the course of azeotropic separation, and the azeotropic separation refers to the process of feeding the mixture containing sec-butyl acetate, acetic acid and heavier hydrocarbons into the azeotropic rectification column, adding azeotropic agent for azeotropic rectification, and evaporating the azeotrope formed by sec-butyl acetate and azeotropic agent from the top of the column, and acetic acid and the heavier hydrocarbons falling into the bottom.
