Abstract: 2-NITRO-4,6-DICHLORO-5-METHYLPHENOL IS PREPARED BY THE SULFONATION OF 4-CHLORO-5-METHYLPHENOL TO FORM 2-SULFO-4-CHLORO-5-METHYLPHENOL WHICH IS CHLORINATED TO 2-SULFO-4,6-DICHLORO-5-METHYLPHENOL WHICH IS IN TURN REACTED WITH NITRIC ACID TO FORM THE DESIRED PRODUCT. The sulfonation is carried out with concentrated sulfuric acid at elevated temperatures to form 2-sulfo-4-chloro-5-methylphenol. Thereafter the reaction mixture is diluted with water to a sulfuric acid content of 20-30%. The resulting 2-sulfo-4-chloro-5-methylphenol is chlorinated with chlorine at elevated temperature and normal or elevated pressures to form 2-sulfo-4,6-dichloro-5-methylphenol which is then reacted with nitric acid.

Abstract: A method for preparing 2-nitro-4, 6-dichloro-5-methylphenol and the corresponding 2-amino compound comprising sulfonating 4chloro-5-methylphenol with a sulfuric anhydride complex in a halogenated hydrocarbon solvent, chlorinating the thus obtained 2-sulfo-4-chloro-5-methylphenol, replacing the sulfonic group of the resulting 2-sulfo-4, 6-dichloro-5-methylphenol with a nitro group and, when the 2-amino compound is required, reducing the nitro group to the amino group is disclosed. The product is useful as an intermediate in preparing a cyan coupler.
