順酐(簡稱MA)是順丁烯二酸酐的簡稱,又名馬來酸酐或失水蘋果酸酐;英文名:Mateicanhydride;分子式:C4H203;分子量:98.058;
Maleic anhydride (MA) is the abbreviation of maleic anhydride, also known as maleic anhydride or dehydrated malic anhydride; English Name: matericanhydride; molecular formula: c4h203; molecular weight: 98.058; molecular weight: 98.058;
順酐是一種常用的重要基本有機化工原料,是世界上僅次于醋酐和苯酐的第三大酸酐原料。
Maleic anhydride is an important basic organic chemical raw material, which is the third largest anhydride raw material in the world after acetic anhydride and phthalic anhydride.
順酐主要用于生產不飽和聚酯樹脂(UPR)、醇酸樹脂。此外,以順酐為原料還可以生產1,4-丁二醇(BOD)、γ-丁內酯(GBL)、四氫呋喃(THF)、馬來酸、富馬酸和四氫酸酐等一系列用途廣泛的精細化工產品,在農藥、醫藥、涂料、油墨、潤滑油添加劑、造紙化學品、紡織品整理劑、食品添加劑以及表面活性劑等領域具有廣泛的應用。
Maleic anhydride is mainly used to produce unsaturated polyester resin (UPR) and alkyd resin. In addition, maleic anhydride can also be used as raw material to produce a series of fine chemical products, such as 1,4-butanediol (BOD), γ - butyrolactone (GBL), tetrahydrofuran (THF), maleic acid, fumaric acid and tetrahydroanhydride. It has a wide range of applications in the fields of pesticides, medicine, coatings, ink, lubricant additives, paper chemicals, textile finishing agents, food additives and surfactants Application.
上工業化生產順酐的工藝路線主要為正丁烷法氧化法,其次為苯氧化法,我國主要采用苯氧化法。
In the world, n-butane oxidation is the main process for the industrial production of maleic anhydride, followed by benzene oxidation. In China, benzene oxidation is the main process.
近年來,我國順酐的表觀消費量不斷增加。無論是我國順酐的生產技術,還是生產能力都得到了很大的發展,但是與國外^相比還存在一些問題。
In recent years, the apparent consumption of maleic anhydride in China is increasing. Both the production technology and production capacity of maleic anhydride in China have been greatly developed, but there are still some problems compared with foreign countries.
