Phtalic Anhydride

Phthalic anhydride is a white crystalline compound with a strong, pungent odor. It is derived from the oxidation of naphthalene or ortho-xylene and is soluble in alcohol, ether, and benzene.

Uses:

Phthalic anhydride has a wide range of applications, primarily in the production of plasticizers and resins. It is also used in the production of polyester resins, alkyd resins, and dyes. Additionally, it is used as an intermediate in the production of pharmaceuticals, insecticides, and herbicides.

Industrial Applications:

Phthalic anhydride is a vital component in the manufacturing of various industrial products. It is used to produce plasticizers, which are added to plastics to improve their flexibility, durability, and workability. It is also used in the production of unsaturated polyester resins, which are used in the construction of boats, automotive parts, and pipelines.

Safety and Handling:

Phthalic anhydride can cause severe irritation to the skin, eyes, and respiratory system. Adequate ventilation and protective equipment, such as goggles and gloves, should be used while handling phthalic anhydride. In case of skin contact, the affected area should be immediately washed with water, and medical attention should be sought.

Un number:

The UN number for phthalic anhydride is UN 2214.
