Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome that the existing reactive dyes have high activity, are sensitive to process conditions, and are not easy to control; or the directness is too large, causing the dyes to have poor wet treatment fastness and serious staining on the white background. ; or low fixation rate, resulting in waste of dyestuffs, which is not conducive to environmental protection, increases the difficulty of wastewater treatment, technical problems such as high printing costs, and provides a reactive dyestuff, its composition, preparation method and application

Embodiment 1

[0094] 18.8 parts of cyanuric chloride, 70 parts of ice, 50 parts of water and 0.1 part of Pingping plus O25, beat in an ice bath for 45-60 minutes, then add 54.6 parts of compound 8 synthesized by the usual method (dissolved in 220 parts of water in advance), Carry out a condensation, react at 0-5°C, adjust the pH to 6.5-7.0 with 10% sodium carbonate solution, and react for 3.0 hours. The end point is when there is no compound 8. Compound 9 of the following formula was obtained.

[0095]

[0096] Then 21.2 parts of hydroxyethylethylenediamine Add the above-mentioned one-condensate, heat up to 60°C, carry out two-condensation at 60-65°C, use 10% sodium carbonate solution to adjust the pH of the medium to 6.0-7.0, and react for 8.0-10.0h. When there is no compound 9, it is the end point. Compound 10 of the following formula was obtained. Its molecular weight is 828 as tested by HPLC-MS, which is consistent with its structure.

[0097]

Embodiment 2

[0099] 37.6 parts of cyanuric chloride, 140 parts of ice, 100 parts of water and 0.2 parts of Pingping plus O25, beating in an ice bath for 45 to 60 minutes, and then adding 34.6 parts of m-aminobenzenesulfonic acid (dissolved in 400 parts of water in advance) for a Condensate and react at 0-5°C, adjust the pH to 6.5-7.0 with 10% sodium carbonate solution, and react for 3.0 hours. The end point is when there is no m-aminobenzenesulfonic acid. Compound 11 of the following formula was obtained.

[0100]

Embodiment 3

[0102] 37.6 parts of cyanuric chloride, 140 parts of ice, 100 parts of water and 0.2 parts of Pingping plus O25, beat in an ice bath for 45 to 60 minutes, then add 17.3 parts of m-aminobenzenesulfonic acid and 17.3 parts of p-aminobenzenesulfonic acid (pre-dissolved In 400 parts of water), conduct a condensation, react at 0-5°C, adjust the pH to 6.5-7.0 with 10% sodium carbonate solution, and react for 3.0 hours. The end point is when there is no m-aminobenzenesulfonic acid. Compound 12 of the following formula was obtained.

Abstract

The invention discloses a reactive dye, its composition, preparation method and application. The preparation method of the compound shown in the formula (1) comprises the following steps: in water, under the condition of pH 6.5-7.5, the compound shown in the formula (2) is mixed with the compound shown in the formula (3) and / Or the compound represented by the formula (4) is subjected to the condensation reaction shown below to obtain the compound represented by the formula (1). The reactive dye of the invention not only has the advantages of complete chromatogram of monochloro-s-triazine reactive dye, excellent fastness indexes, no white background staining, high solubility, etc. Dye waste, green and environmental protection, reduce printing costs, more suitable for industrial production. The reactive dye of the invention is suitable for printing, dip dyeing and continuous dyeing on cellulose such as cotton and hemp or protein fibers such as wool and silk, and has simple preparation method, cheap raw materials, and great economic and environmental benefits.

Description

technical field [0001] The invention relates to a reactive dye, its composition, preparation method and application. Background technique [0002] Reactive dyes currently on the market for printing mainly include P-type dyes from Huntsman Company, PN-type dyes from DyStar Company, and domestic K-type dyes. The reactive groups of these dyes are mainly monochloro-s-triazine type. Vinylsulfone type reactive dyes are also used for printing on the market (for example, such reactive dyes are disclosed in US2008216256A1), but because of their high activity, sensitivity to process conditions, and difficult control, they are rarely used in printing. The intermediate mercaptoethylamine of vinyl sulfone type reactive dyes is not a commonly used intermediate of dyes, and there is basically no domestic production, and the price is high; at the same time, the mercaptoethylamine has a foul smell, high toxicity, is unfavorable to the environment, and is not suitable for industrial productio...
