Медь, комплекс 2,2'-[карбонилбис[имино(1-гидрокси-3-сульфо-6,2-нафталиндиил)азо]]бис[бензойной кислоты] химические свойства, назначение, производство
Подготовка
2-Aminobenzoic acid (2 Moore) diazo, and N,N’-bis(4-hydroxy-2-sulfonaphthalene-7-yl)urea?coupled with copper sulfate, and complex.Свойства и приложения
red light brown. Brown powder. Soluble in hot water for red, solubility of 15 g/L (60 ℃), 20 g/L (97 ℃), and adequate soluble in ethanol, slightly soluble in strong hydrochloric acid for yellow, dilute after gradually from orange red. The strong sulfuric acid for red, diluted is still red; In 40% of sodium hydroxide solution in a slightly soluble for light yellow, add water dilute, deepen primary colors. Dyeing copper ions in a slight change color in a little yellow colored light iron ion. Mainly used to viscose filament, natural silk, rayon, wool, linen and its various blended fabric dyeing and printing directly. Also can be used for leather products dyeing.| Standard | Acid Resistance | Alkali Resistance | Light Fastness | Soaping | Water | ||
