順酐是一種化學(xué)物質(zhì),它可以用于制造各種化學(xué)品。順酐的用途有很多,如制造工業(yè)醇、農(nóng)藥、化妝品等。

Maleic anhydride is a chemical substance that can be used to manufacture various chemicals. Maleic anhydride has many uses, such as manufacturing industrial alcohols, pesticides, cosmetics, etc.

　　1：順酐的分類：

1: Classification of maleic anhydride:

　　順酐主要分為兩類，一類是脂肪酸酐，另一類是醇酐。

Maleic anhydride is mainly divided into two categories, one is fatty acid anhydride, and the other is alcohol anhydride.

　　脂肪酸酐是以脂肪酸為原料，經(jīng)過(guò)酸水解、氫化或氫解、堿水解得到；醇酐是以醇為原料，經(jīng)過(guò)酸水解、氫化或氫解、堿水解得到。其中脂肪酸酐主要有環(huán)氧乙烷、丙烯酸酐、丁二烯酸酐、酚、己二酸酐等；

Fatty acid anhydrides are obtained from fatty acids as raw materials through acid hydrolysis, hydrogenation or hydrolysis, and alkaline hydrolysis; Alcohol anhydrides are obtained from alcohols as raw materials through acid hydrolysis, hydrogenation or hydrolysis, and alkaline hydrolysis. Among them, fatty acid anhydrides mainly include ethylene oxide, acrylic anhydride, butadiene anhydride, phenol, adipic anhydride, etc;

　　醇酐主要有乙醇酐、丙醇酐、異丙醇酐、甲醇酐。

Alcohol anhydrides mainly include ethanol anhydrides, propanol anhydrides, isopropanol anhydrides, and methanol anhydrides.

　　2：順酐的用途：

2: The use of maleic anhydride:

　　順酐主要是用作醫(yī)藥中間體，也可以作為農(nóng)藥、染料、涂料、油墨、橡膠、橡塑樹脂、分散劑、聚合物等的生產(chǎn)原料。順酐廣泛應(yīng)用于醫(yī)藥工業(yè)，主要用于制備抗生素、降血脂藥物、鎮(zhèn)痛藥、解熱鎮(zhèn)痛藥、抗癌藥物、抗心律失常藥物、抗過(guò)敏藥物、麻醉藥物等。順酐也應(yīng)用于農(nóng)藥工業(yè)，主要用于制備殺蟲劑、殺菌劑、除草劑、植物生長(zhǎng)調(diào)節(jié)劑等。

Maleic anhydride is mainly used as a pharmaceutical intermediate and can also be used as a raw material for the production of pesticides, dyes, coatings, inks, rubber, rubber resins, dispersants, polymers, etc. Maleic anhydride is widely used in the pharmaceutical industry, mainly in the preparation of antibiotics, lipid-lowering drugs, analgesics, antipyretics and analgesics, anticancer drugs, antiarrhythmic drugs, antiallergic drugs, anesthetic drugs, etc. Maleic anhydride is also used in the pesticide industry, mainly in the preparation of insecticides, fungicides, herbicides, plant growth regulators, etc.
