CAS 2035-75-8

Adipic anhydride

Description:

Adipic anhydride, with the CAS number 2035-75-8, is a cyclic anhydride derived from adipic acid. It appears as a colorless to pale yellow liquid with a characteristic odor. This compound is known for its reactivity, particularly in the formation of polyamides and polyesters, making it a valuable intermediate in the production of nylon and other synthetic fibers. Adipic anhydride is soluble in organic solvents such as acetone and ethanol but is insoluble in water. It has a relatively low boiling point and can undergo hydrolysis in the presence of moisture, reverting to adipic acid. The substance is classified as a skin and respiratory irritant, necessitating careful handling and appropriate safety measures during use. Additionally, it is important to note that adipic anhydride can participate in various chemical reactions, including ring-opening polymerization and acylation reactions, further expanding its utility in organic synthesis and industrial applications.

Adipic anhydride

CAS: 2035-75-8

Adipic anhydride is a solid dispersant that is used in the production of polycarboxylic acids. It is a solid with a melting point of about 210°C and has a high viscosity. Adipic anhydride can be used for the preparation of amides with carboxylic acid or amine derivatives. This compound can also be used to produce polyamide resins, which are degradable plastics that are derived from adipic acid. Adipic anhydride has been found to have moderate toxicity in animal studies, but is not carcinogenic.
