摘要

"Support for use in catalyst for the production of aliphatic acid ester carboxu00eclico reduced catalyst for the production of aliphatic acid ester carboxu00eclico reduced using the support.Process for the production of catalyst, and process for the production of aliphatic acid ester carboxu00eclico reduced using the catalyst.The present invention relates to a siliceous support for use in a catalyst for the production of an aliphatic carboxylic acid ester by reaction of a low olfeina below with an acid CARboxu00edlico aliphatic reduced in a gaseous phase, which has a silicon content from 39.7 to 46.3% by mass, or a silicon content ranging from 85 to 99% by mass in terms of silicon dioxide or a resistance to crushing of 30 n or more.By the use of a catalyst comprising a support,An ester of aliphatic carboxylic acid reduced is produced from aliphatic carboxylic acid and an olefin reduced reduced without causing a large reduction of catalytic activity or cracking theU abrasion of the catalyst.
