Abstract

The invention relates to a process in which phenol is prepared by reacting benzoic acid vapour with molecular oxygen, in contact with metallic copper and in the presence of water vapour. Preferably the copper is applied to a carrier e.g. such as the oxides of zinc, calcium, aluminium, titanium, cadmium, magnesium, barium, cerium, or silicon. In an example benzoic-acid vapour, obtained by passing nitrogen through molten benzoic acid, water vapour and air are passed through a tubular reactor containing a catalyst consisting of copper on magnesium oxide (50% by weight of copper) at a temperature of 250 DEG C., to produce phenol. U.S.A. Specifications 2,727,924, 2,727,926, 2,762,838, 2,766,296, 2,852,567 and 2,956,407 are referred to.
