Continuous coupling process for ester-based azo disperse dye

The invention belongs to the technical field of fine chemical preparation, and particularly relates to a continuous coupling process for an ester-based azo disperse dye. The process includes the stepsthat 1, a coupling component compound containing an ester group or a coupling component mixture containing a compound and an aqueous solution A are simultaneously and continuously added into a mixerfor mixing; 2, a diazonium salt solution and an aqueous solution B are simultaneously and continuously added into another mixer for mixing adjustment; 3, the two raw materials obtained above are mixedand subjected to a reaction at equal moles to obtain a coupling reaction product; 4, the coupling reaction product continuously enters another reactor, and continuous material discharging, suction filtration, washing to neutrality and drying are performed to obtain a disperse dye compound. Through continuous improvement of conventional intermittent coupling reaction processes in a step-by-step mode, the coupling temperature of an easily hydrolyzable coupling component compound under acidic conditions is increased, the dependency on a refrigerant is reduced, the coupling reaction time is greatly shortened at the same time, the hydrolysis of coupling components is reduced, the product yield is increased, the production efficiency is improved, and the COD of mother liquor wastewater is reduced.

Disperse dye composition, and preparation method and application thereof

Disclosed are a disperse dye composition, and a preparation method and application thereof. The disperse dye composition comprises a component A composed of one or more of compounds shown as a formula (1) (please see the specifications for the formula), a component B composed of one or more of compounds shown as a formula (2) (please see the specifications for the formula), forbidden aromatic amine compounds, chlorinated phenols, chlorobenzene and chlorotoluene, optional auxiliaries, and other unavoidable impurities. The total content of the forbidden aromatic amine compounds is 10 ppm or below, the respective content of the various chlorinated phenols is 0.5 ppm or below, and the total content of the chlorobenzene and chlorotoluene is 1 ppm or below. The various environment protection indexes of the disperse dye composition meet the requirements of Oeko-Tex Standard 100(2016). In addition, after fabric is dyed through the disperse dye composition, the dyed fabric meets the baby level requirements of Oeko-Tex Standard 100(2016).

Preparation method of ester group-containing azo disperse dye

The invention discloses a preparation method of an ester group-containing azo disperse dye. The method comprises the following steps: carrying out a coupling reaction on a diazo salt and a coupling component, adding an alkali to the above obtained azo compound material system after the coupling reaction is completed in order to adjust the pH value of the system to 5-7, carrying out heating crystal transformation, and post-processing to obtain a dye filter cake. The pH value of the system is adjusted to 5-7 after the coupling reaction and before the crystal transformation, so hydrolysis of ester groups in the dye product is avoided, the yield of the dye product is improved, and the content of organic matters in wastewater is reduced, thereby the wastewater post-treatment difficulty is reduced.
