Abstract
Process for the production of lower aliphatic esters by bringing together in an addition reaction a lower olefin and a saturated, lower aliphatic, mono-carboxylic acid in the vapor phase into contact with a heterpolyacid catalyst. The reactant olefin and acids and any recycled feeds are rendered substantially free of aldehydes impurities prior to being brought into contact with the heterpolyacid catalyst. Acetaldehyde is a catalyst poison and removal of these from the feeds prolongs life and activity of the heteropolyacid catalyst.
