An efficient production of benzene from benzoic acid in subcritical water using a copper(I) oxide catalyst

Author affiliations

Abstract

A method combining subcritical water technology and a commercially available copper(I) oxide catalyst has been used for the production of benzene from benzoic acid. The benzene yield reached 91 mol% with 100% selectivity at 350 °C and ∼25 MPa in 90 min. This is the first time the reaction from benzoic acid to benzene using an environmentally-friendly, efficient and economical method has been realized. The proposed reaction mechanism indicates that Cu2O was an effective and stable catalyst, and the process was driven by the unique properties of subcritical water: the high ion product, the enhanced solubilisation of products, and the high diffusivity.
