METHOD FOR REGENERATING LOWER ALIPHATIC CARBOXYLIC ACID ESTER PRODUCTION CATALYST, METHOD FOR PRODUCING LOWER CARBOXYLIC ACID ESTER PRODUCTION CATALYST THEREBY, LOWER ALIPHATIC ACID ESTER PRODUCTION CATALYST REGENERATED BY THE REGENERATION METHOD, AND METHOD FOR PRODUCING LOWER ALIPHATIC ACID ESTER BY USING THE CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently regenerating a catalyst in a catalyst used in producing a lower aliphatic carboxylic acid from a lower olefin and a lower aliphatic carboxylic acid and having lowered activity after being used, to obtain a lower aliphatic carboxylic acid ester catalyst regenerated by the regeneration method, and to provide a method for producing the lower aliphatic acid ester by using the catalyst.;SOLUTION: It has been found out that the activity of the catalyst can be regenerated and the reuse of the catalyst becomes possible by heating under conditions including a specified temperature range.;COPYRIGHT: (C)2003,JPO
