| introduction | solvent blue 36 chemical name 1, 4-bis (1-isopropylamine) anthraquinone is a solvent dye with excellent performance, dark blue powder. Insoluble in water, slightly soluble in ethanol, oleic acid, stearic acid, easily soluble in benzene, xylene, chlorobenzene, chloroform and other organic solvents. It is mainly suitable for coloring ABS, PC, HIPS, PMMS and other resins. |
| preparation | isopropanol, polyethylene glycol and 1,4-dihydroxyanthraquinone leophores are sequentially put into a container, stir evenly, add a mixed aqueous solution of monomethylamine and isopropylamine, raise the temperature to 70-75 ℃ for reaction for more than 5 hours, dedissolve to 80- 85 ℃ at normal pressure, and cool to 40-45 ℃ (distilled monomethylamine and isopropylamine), add water, sodium hydroxide and copper sulfate, open the reaction container, stir at 40-45 ℃ for more than 10 hours, filter, wash, dry and discharge. Among them, the mass ratio of 1,4-dihydroxyanthraquinone leophores to isopropanol is 1:(5-7.5), the mass ratio of 1,4-dihydroxyanthraquinone leophores to polyethylene glycol is 1:(0.05-0.25), the mass ratio of 1,4-dihydroxyanthraquinone leophores to 70wt% monomethylamine is 1:(0.357-0.5),1, the mass ratio of 4-dihydroxyanthraquinone crypto to isopropylamine is 1 :( 0.475-0.6), the mass ratio of water in the mixed aqueous solution of 1,4-dihydroxyanthraquinone crypto and monomethylamine and isopropylamine is 1 :( 2.4-3), the mass ratio of 1,4-dihydroxyanthraquinone crypto water is 1 :( 10-15),1, the mass ratio of 4-dihydroxyanthraquinone crypto sodium hydroxide is 1 :( 0.2-0.3), and the mass ratio of 1, 4-dihydroxyanthraquinone crypto copper sulfate is 1 :( 0.025-0.1). Among them, 1-methylamino -4-isopropylamino anthraquinone (solvent blue 102) accounts for 82-88% of the effective component of the product, 1,4-di (methylamino) anthraquinone accounts for 8-12% of the product component, 1,4-di (isopropyl) amino anthraquinone (solvent blue 36) accounts for 4-6% of the product component. |
| use | transparent blue AP is mainly used for coloring various plastics and acetate fibers, and can also be used for coloring polyester fiber puree. can be used for coloring a variety of plastics and polyesters |
| Production method | Using 1, 4-dihydroxyanthraquinone and isopropylamine as raw materials, 1, 4-dihydroxyanthraquinone is first reduced to its letho Body, then condensed with isopropylamine, and then oxidized to obtain the product. The finished product is filtered and dried.. |
