Regeneration of catalyst for use in production of lower aliphatic carboxylic acid ester and production of lower aliphatic carboxylic acid ester

摘要

A catalyst for use in the production of a lower aliphatic carboxylic acid ester by reacting a lower olefin and a lower aliphatic acid ester in a gas phase, which catalyst has been decreased in activity through use, is regenerated by heating to be recovered in activity. The regenerated catalyst is reused for the production of a lower aliphatic carboxylic acid ester.
