Title:
PRODUCTION METHOD OF ALIPHATIC CARBOXYLIC ACID ESTER
Document Type and Number:
WIPO Patent Application WO/2019/049838
Kind Code:
A1
Abstract:
To increase the activity of a solid acid catalyst used for the production of an aliphatic carboxylic acid ester and thereby achieve efficiency enhancement in the production of an aliphatic carboxylic acid ester. In a method for producing an aliphatic carboxylic acid ester by reacting an aliphatic carboxylic acid having from 1 to 5 carbon atoms and an olefin having from 2 to 4 carbon atoms in a gas phase by use of a solid acid catalyst, a solid acid catalyst in which a heteropolyacid or a salt thereof is supported on a silica carrier obtainable by kneading fumed silica obtained by a combustion method, silica gel obtained by a gel method, and colloidal silica obtained by a sol-gel method or a water glass method, molding the resulting kneaded product, and calcining the resulting molded body, is used.
