Physical and Chemical Properties | Chemical properties dark red uniform powder. Soluble in water and bright red. The color light of dyeing at high temperature (120 ℃) is unchanged, the color of copper ion is slightly changed during dyeing, and the color of iron ion is unchanged. In the range of pH = 2-6, the color light is stable and the levelness is good. The color light is unchanged when the bath is dyed with sulfuric acid or formic acid. Light fastness level 6. Compatibility value K = 4. |
Use | Application: cationic brilliant red 5GN is suitable for dyeing acrylic bulk fiber, fiber strip and acrylic wool, which is bright red. It can also be used for dyeing diacetate fiber and chloron fiber and for direct printing of acrylic fiber, diacetate fiber and acid-modified polyester fabric. It is suitable for dyeing wool nitrile and polynitrile blended fabrics, with little staining of wool and nylon. It can be combined with cationic gold yellow X-GL to dye a variety of bright red to red colors on the acrylic wool blanket, and is also used for direct printing. |

EPA chemical information | C. I. Basic Red 14 chloride (12217-48-0) |
Using N-methylaniline and triple division as the main raw materials, first N-methylaniline is cyanoethylated and aldehyde-based to obtain N-methyl-N-(β-cyanoethyl) aminobenzaldehyde, and then it is condensed with triple division to obtain the product by salt, filtration, and drying...
Add 42.2kg of triplicator (90%) into the mixer, stir for 10min, then add 30.5kg of phosphoric acid (85%) and 5.5kg of oxalic acid, stir for 10min, then add 41.4kg N-methyl-N-(β-cyanoethyl) aminobenzaldehyde (100%), continue to stir for 10min, shovel down some materials stuck on the tower wall, add 500kg of levelling agent, heat in, it can be dried to obtain 103-107kg of dye.
