Hexahydrophthalic anhydride

Description:

Hexahydrophthalic anhydride (CAS 85-42-7) is a cyclic anhydride derived from hexahydrophthalic acid. It is a colorless to pale yellow solid at room temperature, known for its low volatility and high reactivity, particularly in the context of polymer chemistry. This compound is characterized by its ability to undergo ring-opening reactions, making it useful as a hardener in epoxy resins and as a curing agent in various thermosetting plastics. Hexahydrophthalic anhydride is soluble in organic solvents such as acetone and ethyl acetate but has limited solubility in water. Its chemical structure contributes to its stability and resistance to hydrolysis under normal conditions, although it can react with water to form hexahydrophthalic acid. Safety considerations include potential skin and respiratory irritation upon exposure, necessitating appropriate handling measures. Overall, hexahydrophthalic anhydride is valued in industrial applications for its performance in enhancing the mechanical properties of materials.
