Abstract

1,251,844. Aromatic nitroso compounds. IMPERIAL CHEMICAL INDUSTRIES Ltd. 11 June, 1969 [3 July, 1968], No. 31788/68. Heading C2C. A nitroso compound of the formula R.NO, where R is an aromatic radical such that the nitroso compound R.NO is volatile is prepared by a process comprising heating an aromatic of the formula R.NO 2 with a heavy metal oxalate in a reaction zone through which passes a current of non-reacting gas to remove from said zone the nitrosocompound which is produced. Examples describe the preparation of nitrosobenzene, m-nitronitrosobenzene and p-nitrosoanisole using ferrous, cobalt, manganese and copper oxalates.
