说到顺酐可能很多人不太清楚，听起来有点陌生，今天
顺酐厂家小编给你详细介绍一下顺酐。
When it comes to maleic anhydride, many people may not be very clear, which sounds a bit unfamiliar. Today, the editor of the maleic anhydride manufacturer will give you a detailed introduction to maleic anhydride.
顺酐是一种大宗原料，那你知道它的由来吗？顺酐全名为顺丁烯二酸酐，又称为马来酸酐，是一种有强烈刺激气味的无色结晶粉末，于1834年由苹果酸得到。早期，顺丁烯二酸酐是通过苯的催化氧化制备，但为了降低成本，改用正丁烷氧化法制取。
Maleic anhydride is a bulk raw material, do you know its origin? The full name of maleic anhydride is Maleic anhydride, also known as maleic anhydride, which is a colorless crystalline powder with strong pungent smell. It was first obtained from Malic acid in 1834. In the early days, Maleic anhydride was prepared by catalytic oxidation of benzene, but in order to reduce production costs, n-butane oxidation method was used.
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；
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, insoluble in Petroleum ether and carbon tetrachloride, and reacts with hot water to form Maleic acid;
顺酐的外观是白色片状结晶，有粉末状、针状、片状、丸状、棒状、团块状或熔融物质，相对密度是1.480，熔点在52.8℃，沸点是202.2℃，闪点：110.0℃。
The appearance of maleic anhydride is a white crystalline flake, consisting of powder like, needle like, flake like, pellet like, rod like, agglomerate like or molten substances. The relative density is 1.480, the melting point is 52.8 ℃, the boiling point is 202.2 ℃, and the flash point is 110.0 ℃.
顺酐的作用：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，不饱和聚酯树脂、醇酸树脂、长效碘胺的原料。
The function of maleic anhydride: it is used for the synthesis of dienes, the production of drugs, pesticides, dye intermediates, the production of polyester resin, alkyd resin, Maleic acid and other organic acids, as well as fat and oil preservatives, and the production of unsaturated polyester resin, alkyd resin, long-acting iodamine raw materials.
也是涂料、马来松香、聚马来酐、顺酐-苯乙烯共聚物的共聚单体，也是油墨助剂、造纸助剂、增塑剂、酒石酸、富马酸、四氢呋喃等的有机化工原料。
It is also a comonomer of coatings, maleic rosin, polymaleic anhydride, maleic anhydride styrene copolymer, and an organic chemical raw material for the production of ink additives, papermaking additives, plasticizers, Tartaric acid, fumaric acid, tetrahydrofuran, etc.
The origin of maleic anhydride is like this. I hope it can help you. If you have any other matters, please come to our website http://www.jnjhhg.cn Consult!
