順酐全名為順丁烯二酸酐（Maleicanhydride），又稱(chēng)為馬來(lái)酸酐，是一種有強烈刺激氣味的無(wú)色結晶粉末，順酐由苯經(jīng)催化氧化或由丁烯或丁烷用空氣氧化而制得，溶于乙醇、乙醚和丙酮，難溶于石油醚和四氯化碳，與熱水作用而成馬來(lái)酸；用于雙烯合成、制藥物、農藥、染料中間體及制聚酯樹(shù)脂、醇酸樹(shù)脂、馬來(lái)酸等有機酸，也用作脂肪和油防腐劑等。
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.
