Description

technical field [0001] The invention relates to a compound synthesis device, in particular to a production device for synthesizing pigment sulfonated indigo. Background technique [0002] Sulfonated indigo is mainly used for dyeing cotton yarn, cotton cloth, wool or silk. This pigment is the product of pigmentation treatment of important vat dye indigo. It has excellent light fastness, weather fastness and heat resistance stability, and gives a blue tone , and can prepare liquid dispersion formulations, mainly used in viscose fiber puree coloring and printing and dyeing. Used for biochemical agents and indicators, as well as dyeing of cotton yarn, cotton cloth, wool or silk, etc. Sulfonated indigo can also be used as a food coloring agent. In fruit juice drinks, carbonated drinks, prepared wine, candies, cakes, colored decorations, dyed canned cherries, and green plums, the maximum usage amount is 0.10g / kg; The dosage is 0.01g / kg. Most of the existing production devices a...
