Supply reasonable price 548-62-9 Crystal Violet global trader 

crystal violet is also called gentian violet and alkaline violet 3. it is also called methyl green, neutral red, methylene blue, safranine, hematoxylin, malachite green, methyl violet and alkaline fuchsin, which are commonly used synthetic basic dyes at present. the dye index number CIBasic Violet 3 (42555) and belong to triaminotriphenylmethane compounds, the appearance is dark green powder or flake crystals with bronze luster. The commercial product is a mixture of 4. 5. hexamethyl alkaline parabuchsin hydrochloride, and the content of hexamethyl derivatives is not less than 96%.
crystal violet industrial products are called alkaline violet 5BN and alkaline elitides, which are mainly used for dyeing silk, acrylic fiber, hemp, paper and leather, as well as pigments, printing oil and inks.

using N,N-dimethylaniline as raw material, it is obtained by oxidation and condensation in the presence of copper sulfate, phenol and salt, and then it is obtained by refining steps such as alkaline conversion, acid conversion, salting-out, and the finished product is obtained by filtration and drying. Alkaline violet 5BN can also be synthesized by the route of Mie ketone, that is: 76mL of water, 8g of anhydrous copper sulfate, 2.4g of phenol, 11.7g of salt and additives (the additives are surfactants or emulsifiers) are added to the reactor. The optimal feeding ratio (mass ratio) for oxidation condensation reaction is 35mL of N,N-dimethylaniline: copper sulfate: phenol: sodium chlorate: additive = 1:0.25:0.125:0.3:0.07) solution (5%) and 24.2gN,N-dimethylaniline, the temperature is raised to 60 ℃, the temperature is kept at 70 ℃ for 3 hours, and 100mL of sodium chlorate solution (containing NaClO36.4 g) is slowly added dropwise, add it within 4 hours and continue the reaction 1.Chemicalbook5h. Cool, let stand, pour out the supernatant, the lower solid is the oxidation condensation product, and grind it for later use.
300mL of water and 20.5mL of sodium hydroxide solution (30%) are added into the reactor, and the oxidation condensation product is added under stirring. Slowly raise the temperature to 40 ℃, then uniformly raise the temperature to 80 ℃ within 3h, then raise the temperature to 90 ℃ within 1h, and keep the temperature at 95 ℃ for 0.5h. Then add water to the total volume of 800mL, add sodium sulfide solution (10%) dropwise at 60-70 ℃, and continue the reaction for 1.5h. Cool, filter, wash to pH = 8-9, filter cake for later use. Add 50mL of water and 3mL of sulfuric acid (65%) into the reactor, add the above filter cake under stirring, raise the temperature to 90-100 ℃ for 40min, filter while hot, and wash the filter cake with hot water. Merge the filtrate and washing liquid, evaporate and concentrate at 60 ℃ to about 50mL, cool, salted out, let stand, pour out the clear liquid, and the solid is dried to obtain the dye product.
