說(shuō)到順酐可能很多人不太清楚，聽(tīng)起來(lái)有點(diǎn)陌生，今天
順酐廠家小編給你詳細(xì)介紹一下順酐。
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.
順酐是一種大宗原料，那你知道它的由來(lái)嗎？順酐全名為順丁烯二酸酐，又稱(chēng)為馬來(lái)酸酐，是一種有強(qiáng)烈刺激氣味的無(wú)色結(jié)晶粉末，于1834年由蘋(píng)果酸得到。早期，順丁烯二酸酐是通過(guò)苯的催化氧化制備，但為了降低成本，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.
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；
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;
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(duì)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, 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 ℃.
順酐的作用：用于雙烯合成、制藥物、農(nóng)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(jī)酸，也用作脂肪和油防腐劑等，不飽和聚酯樹(shù)脂、醇酸樹(shù)脂、長(zhǎng)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、馬來(lái)松香、聚馬來(lái)酐、順酐-苯乙烯共聚物的共聚單體，也是油墨助劑、造紙助劑、增塑劑、酒石酸、富馬酸、四氫呋喃等的有機(jī)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.
