Versuchsvorschrift

A pressure vessel was charged with 4.71 g of phenol, 16.05 g of potassium 3,5-xylenolate being in a dry powder form and 38 g of NeoSK 1400. With stirring, reaction was carried out at a carbon dioxide pressure of 5 kg/cm2 (G) and at 300° C. for one hour. An analysis of the reaction mixture after conversion to acid form showed a para-hydroxybenzoic acid yield of 78.4% on the basis of phenol.
