Reactive dye for red wool, preparation method thereof and dye solution |
| abstract |
The application relates to the field of dyes, and particularly discloses a reactive dye for red wool, a preparation method thereof and dye liquid. The reactive dye for red wool has a structural formula R1 and R2 are both auxochrome groups, and M is a metal element; the preparation method of the red wool reactive dye comprises the following steps: condensing an ester compound and N-methyl sodium taurate to obtain a first condensation compound; diazotizing the first condensation compound to obtain a diazo; condensing H acid and 2, 3-dibromo propionyl chloride to obtain a second condensation compound; and (4) coupling the second condensation compound with a diazo to obtain the red reactive dye for wool. The reactive dye in the application has short dyeing time and is not easy to generateAnd (4) color spots. |
