Summary:在低级烯烃与低级脂族羧酸在气相中反应生产低级脂族羧酸酯中所用的、使用后活性已下降的催化剂通过加热而再生以恢复活性。所述再生催化剂再用于生产低级脂族羧酸酯。 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.
