Abstract
Butyl (isobutyl) p-hydroxybenzoate were synthesized with reaction of p-hydroxybenzoic acid and butanol (isobutano), by aminosulfonic acid as catalyst. The optimum conditions are as followings: the ratio of butanol, p-hydroxybenzoic acid, aminosulfonic acid is 0.25 mol:0.05 mol:0.5 g, reaction for 3 h. The yield is 75.6%(76.3%). The products were characterized by IR, m.p., element.
