Lange, Schwefelfarbstoffe, 132, 381 Dye Derived from Dinitro-/-cresol Formation.--12 parts of sodium p-nitro-toluene-sulfonate are dissolved in 50 parts of hot water, and treated with 100 parts of sodium hypochlorite solution (2 per cent HOC1) and 50 parts of caustic soda solution (40) at 70. At end of reaction, cooled with ice to 40 and after crystallizing several hours, the product is filtered off.
