Succinic anhydride
CAS: 108-30-5
Chemical formula: C4H4O3
1. Nature:
-Appearance: Succinic anhydride is a colorless to light yellow solid with an irritating odor.
-Solubility: soluble in polar solvents such as water, alcohol, and ether.
-Stability: It has relatively high stability, but is prone to polymerization reactions under conditions such as light, heat, and oxygen.
2. Purpose:
-Succinic anhydride can be used as an important intermediate in organic synthesis, commonly used in the synthesis of flexible polyester, coatings, plastics, resins, and other compounds.
-It is also widely used in the preparation of polymer materials such as acrylic copolymer, polyimide, and polyamide.
-In addition, succinic anhydride can be used in research fields and in chemical laboratories for the synthesis and analysis of compounds.
3. Preparation method:
-Succinic anhydride is often prepared through the anhydride reaction of succinic acid. A common preparation method is to react succinic acid with acylating agents (such as acid chlorides or anhydrides) under appropriate reaction conditions to obtain succinic anhydride.
4. Safety information:
-Succinic anhydride can cause irritation and corrosion to the eyes, skin, and respiratory tract at high concentrations. Therefore, protective gloves and glasses should be worn when using to ensure a well ventilated environment.
-Avoid contact with strong oxidants and high temperatures to prevent dangerous situations such as explosions or fires.
-Be careful when using and storing succinic anhydride, and follow the correct operating methods and safety precautions.
