Environmentally friendly preparation method of solvent blue 63 dye

The invention relates to an environmentally friendly preparation method of a solvent blue 63 dye. The preparation method comprises (a) adding m-toluidine into a reaction container, orderly adding 1-methylamino-4-bromoanthraquinone, an alkali metal hydroxide and a copper salt into the reaction container along with stirring, heating the mixture to 100 to 130 DEG C and carrying out a reaction process for 4 to 7 hours until a terminal point, wherein a mass ratio of 1-methylamino-4-bromoanthraquinone, m-toluidine, alkali metal hydroxide to copper salt is 6: 12-16: 3-4: 0.04-0.08, and (b) cooling the product obtained by the step a to 60-70 DEG C, then adding methanol into the product, carrying out separation, carrying out stirring, carrying out cooling to 30-50 DEG C, and carrying out filtration, washing and drying. The method has the advantages of high reaction purity, few side reactions, short reaction time, obvious crystallization, washing easiness and less washing wastewater.
