順酐又名馬來酸酐或失水蘋果酸酐，順酐廠家直銷，常簡稱順酐。無色結晶，有強烈刺激氣味，凝固點52.8℃，沸點202℃，易升華。主要由苯或碳四餾分中的正丁烷或丁烯氧化而制得，長期供應順酐，是不飽和聚酯及有機合成的原料。
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.
制造聚酯樹脂、醇酸樹脂、農藥、富馬酸、紙張處理劑等。 順酐是重要的有機化工中間體，可用于制作塑 用途廣泛
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
料工業中的增塑劑；造紙業中的紙張處理劑；合成樹脂產業中的不飽和聚脂樹脂；涂料業中的醇酸型涂料；農藥中的合成；醫藥產業中磺胺藥品的等。近年來以其為主要原材料的丁二酸、酒石酸產業迅速擴大，其在工程建筑、食品調味劑、生物拆分劑等領域的應用得以不斷擴大。以順酐為原料的下游衍生物如1，天津順酐，γ丁內脂等亦有很大的發展。
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.
順酐應急處理處置方法編輯泄漏應急處理隔離泄漏污染區，周圍設警告標志，建議應急處理人員戴好防毒面具，穿化學防護服。不要直接接觸泄漏物，用潔凈的鏟子收集于干燥潔凈有蓋的容器中，運廢物處理場所。如大量泄漏，順酐廠家，收集回收或無害處理后廢棄。
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.
