METHOD FOR DIRECTLY PRODUCING METHYL ACETATE AND/OR ACETIC ACID FROM SYNGAS

Document Type and Number:

WIPO Patent Application WO/2019/061358

Kind Code:

A1

Abstract:

A method for directly producing methyl acetate and/or acetic acid from syngas, the reaction process being completed in at least two reaction zones, the method comprising: causing a raw material containing syngas to enter a first reaction zone to contact and react with a metal catalyst; causing an obtained out-flowing substance to enter a second reaction zone directly or after the addition of carbon monoxide so as to contact and react with a solid acid catalyst; separating the obtained out-flowing substance to obtain a product of methyl acetate and/or acetic acid, and optionally returning a residual part to enter the first reaction zone and/or the second reaction zone for cyclic reaction. The present application provides a novel method for directly converting syngas into methyl acetate and/or acetic acid, the method having a simple processing procedure and high product selectivity. According to the method, the product selectivity of the product of methyl acetate or acetic acid is greater than 93%, and the quantity of methyl acetate and acetic acid may be adjusted according to processing, thus the method has great industrial application prospects.
