Begacron Scarlet GS - Reference Information
| LogP | 5.8 at 20℃ |
| Use | disperse red G-S is suitable for dyeing polyester, acetate fiber and nylon, and is a medium-temperature bright red dye. Suitable for high temperature and high pressure method and hot melt method of dyeing. The dyeing properties and the fastness were good. When it is used for dyeing polyester/cotton blended fabrics, the staining of cotton is more stable. |
| production method | with 2-amino -5 (or 7), 6-dichlorobenzothiazole and N-ethyl-N-cyanoethyl aniline were used as starting materials. The former was first diazotized and then coupled with the latter to obtain the product. The final product was obtained by filtration, grinding and drying.. 190g of H2SO4 (98%) and 20.6g of 2-amino -5, 6-dichlorobenzothiazole were added to the diazotization reaction flask, and the mixture was stirred and heated to 50 ° C. For dissolution. Cool to 30-40 ℃, add 130g water, continue to cool to -2 ℃, slowly add 6mL NaNO2 solution (60%) Dropwise, and keep the temperature at 0 ℃ for 2H to obtain diazo liquid. Add 100ml of water, 26g of H2SO4 (98%) and 18g of N-ethyl-N-cyanoethyl aniline to dissolve in the coupling reaction flask, cool to 0 ℃, add 5g of sulfamic acid, and then add Dropwise nitrogen solution, add to 0 °c for 3h, add NaOH solution (30) to adjust the pH value to 1, keep the heat for 1.5h, warm up to 50-60 °c for 1h. Filtering, washing, drying to obtain the finished product. |
