CATALYST FOR USE IN PRODUCING LOWER FATTY ACID ESTER, PROCESS FOR PRODUCING THE CATALYST, AND PROCESS FOR PRODUCING LOWER FATTY ACID ESTER USING THE CATALYST

摘要

A CATALYST FOR PRODUCING LOWER FATTY ACID ESTERS THROUGH ESTERIFICATION OF LOWER ALIPHATIC CARBOXYLIC ACID WITH A LOWER OLEFIN, COMPRISING A HETEROPOLY ACID OR A SALT THEREOF HELD ON A CARRIER, AND HAVING A SPECIFIC SURFACE AREA OF THE CATALYST, AS MEASURED BY A BET METHOD, OF 65 M2/G-350 M2/G. A PROCESS FOR PRODUCING THE CATALYST AND A PROCESS FOR PRODUCING A LOWER FATTY ACID ESTER BY USING THE CATALYST ARE ALSO PROVIDED.
