Abstract

1278576 Nitrophenols DEFENCE SECRETARY OF STATE FOR 24 Nov 1969 [29 Nov 1968 27 Aug 1969] 56724/68 and 42571/69 Heading C2C Nitrophenols are prepared by a process comprising adding over a period of time a liquid suspension containing from about 4 to about 20% weight/volume of a nitrosated phenol to a nitric acid solution containing between 45 and 100% by weight of nitric acid, said solution being maintained at a temperature in the range from about 45‹ to 100‹ C. The preparation is described of 2,4-dinitrophenol, styphnic acid picric acid, methyl-, dimethyl -, tertiarybutyl and methoxy picric acids, trinitrophloroglucinol, 2-nitro- and 2,4-dinitronaphthols.
