The invention relates to a disperse brilliant blue dye mixture which is formed by mixing two parts, namely dye and auxiliaries, the dye comprises a component A and a component B, the general formula of a compound in the mixed dye of the component A and the component B contains ether bonds, the mixed dye has good affinity with polyester fibers, good dyeing leveling property and high lifting power, and the ether bonds are relatively stable, are not easy to hydrolyze, are particularly stable under alkaline conditions, can be dyed under the alkaline conditions, and have good color fastness. The disperse brilliant blue dye composition solves the problem of poor alkali resistance of disperse blue 284 products, keeps the obvious advantages of bright color, good leveling property and high lifting power, is low in price and economic and environment-friendly in production process, and is rare and good in performance.

The invention provides a continuous synthesis method of disperse yellow dye, belongs to the technical field of fine organic chemical industry, adopts a continuous tubular reaction technology, and provides a continuous tubular reactor which is small in volume, large in specific surface area and large in heat transfer area per unit volume, and can transfer reaction heat in time in a heat exchange manner, so that the yield of the disperse yellow dye is improved. And safety can be ensured while the feeding speed is increased. According to the continuous tubular reaction provided by the invention, the raw material ratio is accurately controlled, so that the feeding ratio of main raw materials is close to a theoretical value, and an automatic control system is introduced, so that the raw material ratio can be strictly subjected to a chemical reaction according to an optimal set value. The mass and heat transfer effect of the continuous reactor is good, after the mass and heat transfer effect ...
