【Abstract】 The paper introduces the preparation of four kinds of heteropoly-tungstic acids and their salts and their use in catalytic synthesis of new plasticizer n-DOP (Di-n-octyl phthalate). Aluminum phospho-tungstate has the best catalytic effect. The optimum reaction conditions of esterification have been found. Its application in industrial production is expected.更多还原
