Preparation and Properties of Modified Rosin-condensed Tannins Esters
摘要
Abstract
Under microwave irradiation and in the presence of pyridine as catalyst,aseries of modified rosin-condensed tannins esters were synthesized by O-acylation reaction between condensed tannins and modified rosin chloride.The target products were analyzed and characterized by means of UV,IR,TG-DTA and elemental analy-sis.In addition,antioxidant activity and surface activity of the esters were determined.The test results showed that modified rosin-condensed tannins esters have better oil-solubility in peanut oil and better antioxidant activity than those of condensed tannins,and that of dehydroabietic acid-condensed tannins ester(DHA-MET)was the best of all.The surface activity was evaluated by surface tension,emulsifying power and foaming ability.The results indicated that sodium salts of the modified rosin-condensed tannins esters,especially sodium salts of the hydrogenated rosin-condensed tannins esters,had the superior surface activity.关键词
