顺酐全名为顺丁烯二酸酐（Maleicanhydride），又称为马来酸酐，是一种有强烈刺激气味的无色结晶粉末，顺酐由苯经催化氧化或由丁烯或丁烷用空气氧化而制得，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。

Maleic anhydride, also known as maleicanhydride, is a colorless crystalline powder with a strong pungent smell. Maleic anhydride is prepared by catalytic oxidation of benzene or oxidation of butene or butane with air. It is soluble in ethanol, ether and acetone, but insoluble in petroleum ether and carbon tetrachloride. It reacts with hot water to form Maleic acid; It is used in diene synthesis, drugs, pesticides, dye intermediates, polyester resin, alkyd resin, maleic acid and other organic acids, as well as fat and oil preservatives.
