Vk. Gumaste et al., AN EFFICIENT USE OF ZEOLITE CATALYSTS FOR ESTERIFICATION OF CARBOXYLIC-ACIDS, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 35(11), 1996, pp. 1174-1179
A mild and practical method (batch process) for the esterification of
carboxylic acids with alcohols using zeolite catalysts in good to exce
llent yields is described. The esterification of phenylacetic acid wit
h ethanol has also been carried out in very high yield using continuou
s flow fixed bed reactor.
