Catalyst for the production of lower aliphatic acid esters carboxu00eclico

摘要

"A catalyst for the production of lower aliphatic acid esters carboxu00eclico".The invention relates to a catalyst for use in the production of lower aliphatic carboxylic acid ester, which can provide high initial activity and high productivity.To ensure the life of the catalyst sufficiently long in industrial practice.And to reduce the production of by-products; a process for the production of the catalyst; and a process for producing a lower aliphatic carboxylic acid ester using the catalyst.The catalyst is produced by a process comprising a step of placing in contact the catalyst heteropoliu00e1cido supported with a gas containing at least one component selected from water,A lower aliphatic carboxylic acid and a lower aliphatic alcohol.
