- 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).

- Disperse dye composition and preparation method and application thereof
-
The invention relates to a disperse dye composition and a preparation method and application thereof. The disperse dye composition comprises a component A as shown in formula (1), a forbidden aromatic amine compound, chlorinated phenol, chlorobenzene, chlorotoluene, any auxiliary materials and other unavoidable impurities. According to the disperse dye composition, the total content of the forbidden aromatic amine compound is 10ppm or lower, the total content of each chlorinated phenol is 0.5ppm or lower, and the total content of chlorobenzene and chlorotoluene (COCs) is 1ppm or lower. Various environment-protective indexes of the disperse dye composition conform to the requirement of Oeko-Tex Standard 100 (2016), and various performance such as the fold strength, sublimation fastness and the like is excellent. Furthermore, after the disperse dye composition of the invention is used for dyeing a fabric, the dyed fabric conforms to the requirements of a baby level of the Oeko-Tex Standard 100 (2016). (Shown in the description).

- Synthesizing method of disperse yellow dye
-
The invention discloses a synthesizing method of a disperse yellow dye. The synthesizing method includes the following steps that 1, metha amino phenon and sodium nitrite are subjected to a diazo-reaction under the acidic condition, and metha amino phenon diazonium salt is obtained; 2, the metha amino phenon diazonium salt obtained in step 1 and a methyl ketone pyridine solution are subjected to a coupling reaction, and a coupling product is obtained; 3, the coupling product obtained in step 2 and benzene sulfonyl chloride are subjected to an esterification reaction, and after the reaction is completed, the disperse yellow dye is obtained through posttreatment. The synthesizing method is easy and convenient to operate, short in process and less in sewage quantity, and the performance is consistent with that of filter cake synthesized through a traditional synthesis method.
