A process for producing a lower aliphatic ester by catalytically reacting a lower olefin and a lower aliphatic carboxylic acid in a gas phase, where the lower aliphatic carboxylic acid is gasified at a relatively low temperature and thereby a mixed gas of the lower olefin and the lower aliphatic carboxylic acid is produced.

Process for producing mixed gas of lower olefin and lower aliphatic carboxylic acid, and process for producing lower aliphatic ester using the mixed gas

A process for producing a lower aliphatic carboxylic acid ester by a gas phase esterification reaction starting from a lower aliphatic carboxylic acid and a lower olefin, comprising adding a lower alcohol corresponding to a hydrate of a lower olefin to the gas phase reaction product, condensing a lower aliphatic carboxylic acid and the lower alcohol and while allowing the conversion into a lower aliphatic carboxylic acid ester to proceed, separating the lower aliphatic carboxylic acid ester. Productivity is increased due to the improvement of the conversion of a lower aliphatic carboxylic acid.
