Product Material
Maleic anhydride, with the chemical formula C4H2O3, is a colorless solid with a fruity aroma.
Usage:
1. Maleic anhydride is one of the important intermediates in the synthesis of polymer, commonly used in the preparation of polybutylene terephthalate (PBT), polyester elastomers, etc.
In organic synthesis, it can be used as an intermediate in the synthesis of compounds such as dyes, pharmaceuticals, and pesticides.
Production process
The common synthesis method of maleic anhydride is obtained through the oxidation reaction of maleic glycol. Commonly used oxidants include benzoyl peroxide, copper nitrate, and hydrogen peroxide.
Precautions for use
The following safety precautions should be taken during storage and use of maleic anhydride:
1. It is necessary to avoid contact with skin and eyes. If in contact, rinse immediately with plenty of water.
During use, it is necessary to maintain good ventilation and avoid inhaling its vapors as much as possible.
3. Avoid contact with oxidants and strong acids to prevent dangerous reactions.
4. Pay attention to fire and explosion prevention measures, stay away from fire sources and high temperatures.
