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.
