Also known as maleic anhydride or dehydrated malic anhydride, maleic anhydride factory direct, often referred to as maleic anhydride. Colorless crystal, strong pungent smell, freezing point 52.8 ℃, boiling point 202 ℃, easy sublimation. It is mainly prepared by oxidation of n-butane or butene in benzene or C4 fraction, and long-term supply of maleic anhydride. It is the raw material for the production of unsaturated polyester and organic synthesis.

制造聚酯树脂、醇酸树脂、农药、富马酸、纸张处理剂等。 顺酐是重要的有机化工中间体，可用于制作塑  用途广泛

Manufacturing polyester resin, alkyd resin, pesticides, fumaric acid, paper treatment agent. Maleic anhydride is an important organic chemical intermediate, which can be widely used in the production of plastics

料工业中的增塑剂；造纸业中的纸张处理剂；合成树脂产业中的不饱和聚脂树脂；涂料业中的醇酸型涂料；农药中的合成；医药产业中磺胺药品的等。近年来以其为主要原材料的丁二酸、酒石酸产业迅速扩大，其在工程建筑、食品调味剂、生物拆分剂等领域的应用得以不断扩大。以顺酐为原料的下游衍生物如1，天津顺酐，γ丁内脂等亦有很大的发展。

Plasticizer in raw material industry, paper treatment agent in paper industry, unsaturated polyester resin in synthetic resin industry, alkyd coating in coating industry, synthesis in pesticide production, sulfonamides production in pharmaceutical industry, etc. In recent years, succinic acid and tartaric acid, which are the main raw materials of succinic acid, have been rapidly expanded, and their applications in engineering construction, food flavoring agent, biological resolution agent and other fields have been continuously expanded. The downstream derivatives of maleic anhydride such as 1, Tianjin maleic anhydride and γ - butanone also have great development.

顺酐应急处理处置方法编辑泄漏应急处理隔离泄漏污染区，周围设警告标志，建议应急处理人员戴好防毒面具，穿化学防护服。不要直接接触泄漏物，用洁净的铲子收集于干燥洁净有盖的容器中，运废物处理场所。如大量泄漏，顺酐厂家，收集回收或无害处理后废弃。

Maleic anhydride emergency treatment method edit leakage emergency treatment isolate leakage pollution area, set warning signs around, suggest emergency treatment personnel wear gas masks, wear chemical protective clothing. Don't touch the leakage directly. Collect it in a dry and clean container with a clean shovel and transport it to the waste disposal site. If a large number of leakage, maleic anhydride manufacturers, collection and recycling or harmless treatment after waste.
