'support for use in catalyst for producing lower aliphatic carboxylic and ester, catalyst for producing lower aliphatic carboxylic acid ester using the support, process for producing the catalyst, and process for producing lower aliphatic carboxylic acid ester using the catalyst'

摘要

A siliceous support for use in a catalyst for producing a lower aliphatic carboxylic acid ester by reacting a lower olefin with a lower aliphatic carboxylic acid in a gas phase, which has a silicon content of from 39.7 to 46.3% by massor a silicon content of from 85 to 99% by mass in terms of silicon dioxide or a crush strength of 30 N or more. By the use of a catalyst comprising the support, a lower aliphatic carboxylic kcid ester is produced from lower olefin and a lower aliphktic carboxylic acid without causing great reduction of catalytic activity or cracking or abrasion of the catalyst.
