METHOD FOR PRODUCING ESTER BY TRANSESTERIFICATION

摘要

A method for producing an ester which comprises contacting a raw material ester and an alcohol such as methanol, with a solid catalyst containing 70 to 95 wt % of an amorphous oxide of zirconium and 5 to 30 wt % of an oxide of titanium, in a manner wherein a mole ratio of the alcohol to the above raw material ester is 5 to 15 mol/mol, to thereby effect a transesterification. The above method allows the practice of a transesterification at a low alcohol consumption and in high yield and thus the production of an ester usable as a diesel fuel.
