Process for producing esters |
| abstract |
A process for producing an ester comprising reacting a carboxylic acid and ethylene in the presence of an acid catalyst in a vapor phase, wherein the concentration of olefin having 3 or more carbon atoms in the starting materials is controlled to 10,000 ppm or less in terms of the molar ratio to the total of the olefin and ethylene. The deterioration of the catalyst can be remarkably prevented from proceeding and a continuous and stable operation can be performed for a long time. |
