ABSTRACT:
A process for making C.sub.8 -C.sub.20 alkyl esters by esterification of 3,5-di-tert-butyl-4-hydroxybenzoic acid with a C.sub.8 -C.sub.20 alcohol. The esterification reaction is conducted at 110.degree.-150.degree. C. in the presence of 5-20 weight percent based on the weight of 3,5-di-tert-butyl-4-hydroxybenzoic acid, of a strongly acidic gel-type ion-exchange resin catalyst having less than about 8 percent cross-linking.
