Physical and Chemical Properties | solubility: insoluble in acetone, slightly soluble in chloroform, O-chlorophenol, nitrobenzene, pyridine, tetralin, toluene and xylene; Green in concentrated sulfuric acid, purple precipitate after dilution; in the alkaline powder solution is blue, the acid changed to red-purple. hue or hue: blue-violet |
Use | The pigment gives a red-violet hue, compared to C.I. Pigment Violet 23 has significantly stronger red light, and has excellent firm performance, with different color depth, light fastness is 7 to 8, at the same time, sweat resistance, dry washing performance is excellent. Mainly in the form of pigment preparation, used for viscose fiber pulp coloring and plastic coloring. |
introduction | reduced violet 1 is isoviolet anthrone dichloride, and the trade name is reduced violet 2R and reduced violet 1. This product is mainly used for dyeing cotton, hemp and viscose fibers and printing of fabrics. It can also be used for processing organic pigments and plastic colorants. reduced violet 1 is an extremely important product in vat dyes. its dyed cotton has bright blue-purple, high affinity, general levelness, good covering power to dead cotton, excellent fastness and 6-grade light fastness. The other fastness is in grade 4-5. It is commonly used in cotton dyeing and direct printing, and has good affinity and levelness for silk, which is favored by the market. |
chemical properties | purple-brown (or blue-black) powder. Insoluble in water, ethanol, acetone, soluble in benzene, slightly soluble in toluene, xylene, chloroform, nitrobenzene, o-chlorophenol, pyridine, tetralin. It is blue in the alkaline solution of hydrosulfite and red and purple in the acidic solution. |
use | reduced purple RR is suitable for dyeing and printing of cotton, hemp, silk and vinylon, as well as dyeing of blended fabrics such as polyester cotton, viscose cotton and vitamin cotton. It is also used to dye dark blue, dark gray and other colors with reduced blue and gray dyes and to make organic pigments. Mainly used for dyeing and printing of cotton fabrics, and can also be processed into pigments for coloring plastics |
production method | benzoanthone is used as raw material to obtain isoviolet anthrone (isoviolanthrone, C.I.60000) through bromination, vulcanization and ring-forming condensation, and then chlorination to obtain the product. The finished product is filtered, crushed and dried.. |
