Heteropolyacid catalyst for producing lower aliphatic carboxylic acid ester.

摘要

A process for producing a lower aliphatic carboxylic acid ester, comprises reacting a lower aliphatic carboxylic acid with a lower alcohol in a gas phase in the presence of a catalyst. The catalyst comprises an inorganic support having supported thereon at least one heteropolyacid and/or a salt thereof. The catalyst exhibits high initial activity and is able to stably and continuously perform the reaction.
