Synthesis of Naphthalic Anhydride by Autoxidation of Acenaphthene in the liquid Phase

Abstract

The synthesis of naphthalic anhydride by autoxidation of acenaphthene in the liquid phase was studied. The effects of reaction temperature, time and oxygen pressure on the coversion of acenaphthene into naphthalic anhydride, and on the yield of naphthalic anhydride and acenaphthenequinone were examined. Naphthalic anhydride was obtained in 67wt% yield at 214°C under oxygen pressure of 30 atm for 2 hour.
