顺丁烯二酸酐在工业上是在五氧化二钒催化下用空气氧化苯制得.甲苯、二甲苯或环烷烃也可作该法的原料.顺丁烯二酸酐主要用于与乙二醇缩聚制造不饱和聚酯树脂,广泛用于制造烘漆、清漆和油墨等.顺丁烯二酸酐是制造反丁烯二酸、丁二酸、酒石酸的原料.
Maleic anhydride is prepared by air oxidation of benzene catalyzed by vanadium pentoxide. Toluene, xylene or cycloalkanes can also be used as raw materials. Maleic anhydride is mainly used to produce unsaturated polyester resin by polycondensation with ethylene glycol, and is widely used in baking paint, varnish and ink. Maleic anhydride is the raw material for the production of fumaric acid, succinic acid and tartaric acid

顺丁烯二酸酐与亚硫酸氢钠加成生成的磺基丁二酸,可用于制造润湿剂.顺丁烯二酸酐还可用于制造农药、医药、染料、石油添加剂和润滑剂.
The sulfonic succinic acid produced by the addition of maleic anhydride and sodium bisulfite can be used to make wetting agent. Maleic anhydride can also be used in the manufacture of pesticides, pharmaceuticals, dyes, petroleum additives and lubricants
为了减少聚合物的生成量,加人阻聚剂,并采用酸作催化剂进行闭环反应,采用玲结晶处理;
In order to reduce the amount of polymer, inhibitor was added and acid was used as catalyst for closed-loop reaction;
按此配方投料,在氮气气氛下加热150℃,再逐步升温到220℃.酸值降40mgKOH/g后加入对苯二酚0.005份,加入苯乙烯使能在反应后彻底去除阻聚剂
According to the formula, heat it to 150 ℃ in nitrogen atmosphere, and then gradually raise the temperature to 220 ℃. When the acid value is reduced to 40mg KOH / g, 0.005 phr hydroquinone is added, and styrene is added to remove the polymerization inhibitor completely after the reaction
