Embodiment 1

[0058] Mix 13.10 grams of 98% sulfuric acid and 16.4 grams of 40% nitrosyl sulfuric acid solution evenly, then slowly add 13.10 grams of 2,4-dinitro-6-bromoaniline at 25 to 28°C, and keep it here after adding The temperature range completes the diazotization reaction. 6.79 g of 2-methoxy-5-acetamido-N-ethyl-N-cyanoethylaniline, 8.42 g of 2-methoxy-5-acetamido-N,N-dimethoxycarbonylmethyl Aniline, 80 mL of water, 20 mL of acetic acid, and 0.2 g of sulfamic acid were mixed to form a mixed solution, which was coupled with the above-prepared diazo liquid at 0-5 ° C. After 3 hours of reaction, the temperature was raised to 65-70 ° C for 2 hours and filtered. , the product was washed with water until the pH value of the eluate was 6-7, and the mixed filter cake of dye compound 1-1 and compound 2-1 (the compound number was shown in Table 1) was obtained, the yield was 94.2%, and the total content of the combined product was analyzed by HPLC was 95.3%.

Embodiment 2

[0063] 14.8 g of 2,6-dibromo-4-nitroaniline was added to 12 g of 98% sulfuric acid at 25 to 35° C. and stirred for 2 hours. Keep at 20~28℃, slowly add 16.4 g of 40% nitrosylsulfuric acid solution dropwise, and then keep at this temperature for 2~4 hours to complete the diazotization reaction. 2 g of N,N-dicyanoethylaniline, 8.2 g of N-methyl-N-benzylaniline, 90 mL of water, 10 mL of sulfuric acid, and 0.2 g of sulfamic acid were mixed into a mixed solution, which was mixed with the prepared diazo liquid above. Coupling reaction occurs at 0-8°C, and the temperature is raised to 65-70°C for 2 hours after the reaction for 3 hours, filtered, and the product is washed with water until the pH value of the eluate is 6-7 to obtain a mixed filter cake of compounds 3 and 4. The yield was 94.4%, and the total content of the combination product was 94.3% by HPLC analysis.

Embodiment 3

[0065] After mixing 28.3 g of the mixture obtained in Example 1 and 21.7 g of the mixture obtained in Example 2 with 65 g of dispersant MF, 5 g of sodium lignosulfonate and 147 g of water, sand-milled and dispersed, and then spray-dried to obtain a disperse dye.

Abstract

An application of a disperse dye composition as disperse dye is disclosed. The disperse dye composition comprises dye and a dispersant. A ratio of the mass of the dispersant to the mass of the dye is 0.5:1-2.5:1. The dye comprises, by weight, 20-65% of a component A, 15-50% of a component B and 15-55% of a component C. The component A is one or more of compounds 1. The component B is one or more of compounds 2. The component C is a compound 3 and / or a compound 4. The composition is good in compatibility, high in printing color yield, good in deep dyeing property, good in lifting capability, excellent in water fasteness, sublimation fasteness and other types of fasteness, significantly improved in white-ground staining, and low in chlorinated phenol residue amount after printing.

Description

technical field [0001] The present invention relates to the application of a disperse dye composition. Background technique [0002] With the continuous enhancement of people's health awareness and environmental protection awareness, "green", "ecological" and "healthy" have gradually become the criteria for consumers to choose textiles. In 2014, the International Environmental Textile Association OEKO-TEX Standard 100 added trichlorophenol to the original list of harmful substances chlorinated phenol on textiles, and set the limits of pentachlorophenol, tetrachlorophenol and trichlorophenol in Class I products. They are specified as 0.05ppm, 0.05ppm and 0.2ppm respectively, and the limits of pentachlorophenol, tetrachlorophenol and trichlorophenol in Class II products are specified as 0.5ppm, 0.5ppm and 2.0ppm respectively. The limits of phenol, tetrachlorophenol and trichlorophenol are specified as 0.5ppm, 0.5ppm and 2.0ppm respectively, and the limits of pentachlorophenol...
