Lipophilization of Phenolic Acids through Esterification Using p-toluenesulfonic Acid as Catalyst
Grain & Oil Science and Technology
Lipophilic antioxidants are used in edible oils and oleaginous foods. Therefore, development of novel lipophilic antioxidant is very important. p-toluenesulfonic acid (PTSA) catalyzed esterification of dihydrocaffeic acid (DHCA) with hexanol was selected as model reaction to investigate the synthesis of lipophilic antioxidant. The highest yield of hexyl dihydrocaffeate was achieved under the following optimum conditions: 1 mol% PTSA, 1:30 molar ratio of dihydrocaffeic acid to hexanol withoutdoi:10.3724/sp.j.1447.gost.2018.18027 fatcat:vyzef2wnivfwbedl6ifcky3ega
