顺酐有强烈刺激气味。溶于乙醇、乙醚和丙酮,难溶于石油醚和四氯化碳。与热水作用而成马来酸。用于双烯合成、制药物、农药、染料中间体及制聚酯树脂、醇酸树脂、马来酸等有机酸,也用作脂肪和油防腐剂等。由苯经催化氧化,或由丁烯或丁烷用空气氧化而制得。
Maleic anhydride has a strong pungent smell. Soluble in ethanol, ether and acetone, insoluble in petroleum ether and carbon tetrachloride. Maleic acid is formed by reacting with hot water. It is used in diene synthesis, medicine, pesticide, dye intermediate, polyester resin, alkyd resin, maleic acid and other organic acids, as well as fat and oil preservatives. It is prepared by catalytic oxidation of benzene or oxidation of butene or butane with air.
