Patent

CA 2308527

The present invention provides a process for preparing (4-nitroso- phenyl)phenyl- hydroxylamine which is characterized in that nitrobenzene is reacted in the presence of hydroxide and/or oxide-containing bases, optionally in the presence of solvents, at temperatures of 20 to 180°C and pressures of 0.1 to 10 bar. The process according to the invention has the particular advantage that it uses in-expensive and cost-effective nitrobenzene as starting material instead of the nitro-sobenzene conventionally used hitherto.
