| brief introduction | c. I. disperse red 177 is benzothiazole heterocyclic disperse dye, and its foreign products are Allilon Red RBLS,Dispersol Red D-2GA and Foron Red S-3GL ~, c. I. disperse red 177 is suitable for high temperature and high exhaustion dyeing of polyester fiber fabrics. it is orange in concentrated sulfuric acid and bright pink after dilution, there is no change in 10% sodium hydroxide solution. It is pink in 10% sulfuric acid. | |
| product properties | c. I. disperse red 17 is an azo dye. Because of the complex structure of the azo structure dye chromogen, the dye structure usually contains multiple nitro, cyano, chlorine, bromine and other substituents, the molecular weight is large, the water solubility is poor, and it is rarely selected as a cationic reactive dye chromogen structure. There are reports in the literature that the azo-containing structure disperse dyes are used as chromopors, and they are modified. In the molecular structure, the polyether chain segment is introduced to improve its water solubility, and the quaternary ammonium salt and halide triazine structure are introduced to prepare cationic reactive dyes containing polyether chain segments and azo structures. | |
| application | c. I. disperse red 17 is used in hot melt dyeing method and printing and other printing and dyeing processes, especially for dyeing of superfine denier fibers. the dye has high dyeing strength, good dyeing property, bright color and excellent fastness. it is a good disperse dye variety. | |
| application example | CN201710593412.4 reported that C.I. disperse red 17 was made into a cationic reactive dye containing azo structure, which is a kind of cationic reactive dye containing azo structure with good water solubility and complete chromatography. The preparation method of this kind of dye is simple, the raw material is cheap, the cost is low, the prepared cationic reactive dye has good water solubility, and the salt-free dyeing effect of cotton fabric is good. (1) dimethylamine (16.05g,0.15mol) and methoxy polyethylene glycol (750) glycidyl ether (80g,0.1mol) are fully compound, fully react at 90 ℃ for 5 hours, decompressed rotary steaming, excess dimethylamine is separated, and the product is collected;(2) The product of step (1) (90.7g,0.1mol) is mixed with trichlorenetriazine (18.5g,0.1mol), the pH value of the reaction system is 5-6 with 5% sodium hydroxide solution. After the reaction is kept at 5 ℃ for 3 hours, the product is not separated. C.I. Disperse Red 17(35g,0.1mol, Hangzhou Baihui Chemical Industry, purity 99%) is added, the temperature is raised to 45 ℃, the reaction pH is maintained at 5-6, the reaction is carried out for 6 hours, the product is extracted and separated with acetonitrile, and the product is spin-dried under reduced pressure. (3) The product in step (2) is dried, dimethyl sulfate (6.3g,0.05mol) is added, and reacted at 60 ℃ for 3 hours to obtain 98.6g of cationic reactive dye with azo structure in P-11 with 95% yield. At room temperature, the P-11 is purplish red viscous liquid. | |
| use | disperse red GG is used for dyeing polyester fiber. for printing and dyeing of polyester and its blended fabrics | |
| Production method | Using p-nitroaniline and 3-methyl-N,N-dihydroxyethylaniline as raw materials. First diazotivate the former, and then couple with the latter to obtain the product. The finished product is filtered, ground and dried.. |
