| Hazard Information | Back Directory | [Chemical Properties]
It is blue-red when soluble in water, insoluble in ethanol and organic solvents. It is green-olive in concentrated sulfuric acid and red-purple after dilution. | [Preparation]
(a) in the presence of Pyridine , with Chlorosulfonic acid treatment C.I. Vat Red 1 leuco : (b) used in Pyridine metal (such as copper, iron, zinc, etc) and Sulfur trioxide source (such as Sulfur trioxide, Chlorosulfonic acid or Methyl chlorosulfonate) processing C.I. Vat Red 1. The above two kinds of circumstances are through with alkali, filter out the insoluble,remove Pyridine and salting-out. | [Properties and Applications]
bright blue light pink to red colourful blue-ray. Greyish-white to pink powder, soluble in water, water solution is red blue light, not soluble in ethanol and other organic solvents: the strong sulfuric acid for green light olive, and for the red light purple diluted. Its water solution have fluorescence, under fluorescent light for purple, salt and is very sensitive to light. Mainly used for the cotton fabric dyeing and printing, although have brittle because its bright light is still widely used. Can direct printing, the printing and dyeing discharge printing. Will dye polyester/cotton, Peacekeeping/cotton and wool, silk fabric, etc. Use polyester melt method dye, the color than cotton bright-coloured.
