Abstract

A process for the prepn. of phthalonitrile comprises reacting o-xylene with ammonia and oxygen, opt. mixed with inert gas, at 350-550 degrees C in the presence of a catalyst deposited on a support. The catalyst is a mixture of either (A)Bi, Sb, Mo and Cr oxides in molar ratio 1 to 15: 1 to 10: 0.5 to 5:0.5 to 20 or (B) Bi, Sb, Mo and V oxides in molar ratio 1 to 20: 1 to 10: 0.1 to 15:1 to 20. The prod. is used to prepare phthalocyanine pigments, dyes, lakes, stabilisers and other materials. Compared with previous processes the above gives a better yield (about 87%) and production rate (about 270 g/l catalyst/hr compared with 100-120 previously).
