CAS Registry Number:53802-03-2
Manufacturing Methods :3-Amino-2-hydroxy-5-nitrobenzenesulfonic acid diazotization, and 3-Oxo-N-phenylbutanamide coupling, and then and Chromium difluoride aqueous solution to common heating product 1 (C.I. 13900). (a)3-(Diethylamino)phenol and Phthalic anhydride condensation, alkali fusion, with sulfuric acid acid solution, and using hydrochloric acid crystallization, (b) 2-(3,6-Dichloro-9H-xanthen-9-yl)benzoic acid and Diethylamine in pressure reaction (BP960088) have to product 2 (C.I. 45170). Then the product 1 and product 2 generation chromium complex.
Properties and Applications:yellow red. Red to brown powder, bright color transparent, in ethanol in higher solubility, heat resistance, light fastness is better. In concentrated sulfuric acid for brown, after diluted solution for light brown. Mainly used for alcohol solvent, ester solvent, varnish, synthetic resin, plastic and wood color.
