摘要： 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.

摘要： 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.
