Benzenesulfonic acid, [[7-(dimethylamino)-4-hydroxy-3-oxo-3H-phenoxazin-2-yl]amino]-, monosodium salt (9CI) химические свойства, назначение, производство
Подготовка
aniline (cold) and mordant Gallocyanine?[by excessive amounts of ?N,N-dimethyl-4-nitrosobenzenamine and Gallic acid Methanol in the reaction (in ethanol in reaction incomplete) and be] hydrochloride (or corresponding diethyl compound) reaction, in 100 ℃ to remove carboxyl, then sulfonation and translated into sodium salt.Синтез
Chromazurin 42 is synthesized anal ogously but in the cold. Under these conditions the aniline group bonds to the position neigh boring the carboxyl group, which is removed by subsequently heating to 100 ℃.Свойства и приложения
green light blue. Soluble in water as dark blue, soluble in ethanol to purple. In concentrated sulfuric acid for wine red, dilution after partial brown color. Dye aqueous solution to join sodium hydroxide as purple.| Standard(cotton) | Ironing Fastness | Light Fastness | Fulling | Persperation Fastness | Soaping | Water | |
