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酸;

Maleic anhydride is produced 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;

順酐的外觀是白色片狀結(jié)晶,有粉末狀、針狀、片狀、丸狀、棒狀、團(tuán)塊狀或熔融物質(zhì),相對密度是1.480,熔點(diǎn)在52.8°℃,沸點(diǎn)是202.2℃,閃點(diǎn):110.0°℃。

The appearance of maleic anhydride is a white crystalline flake, with powder, needle, flake, pellet, rod, clump or molten substances. The relative density is 1.480, the melting point is 52.8 ° C, the boiling point is 202.2 ° C, and the flash point is 110.0 ° C.
