Abstract

PURPOSE: Hydrochloric acid and chloric acid or a chlorate are made to act on 2- nitro-5-methylphenol in an adequate organic solvent to produce in one step high- purity title compound uses as an intermediate for a component of cyan coupler in color films.
CONSTITUTION: Hydrochloric acid 30W35% concentration and chloric acid or a chlorate are made to act on 2-nitro-5-methylphenol in a solvent of benzene bearing nitro groups such as nitrobenzene or nitrotoluene or a chlorinated hydrocarbon of 1W2 carbon atoms such as chloroform or carbon tetrachloride to produce 2-nitro- 4,6-dichloro-5-methylphenol. The reaction temperature is preferably 30W40°C.
