Problems solved by technology

At present, green dyes are mostly prepared by compounding two or three kinds of dyes, but due to the differences in the solubility of compound dyes, directness to fibers during dyeing, reactivity to alkali fixation and other performance differences, resulting in poor dyeing stability, Easy to dye flowers, big difference between head and tail
For example, reactive blue phthalocyanine structure dyes, whose molecules are composed of four isoindoles and form complexes with copper, have good coplanarity, but due to their large molecular weight, their diffusion properties in fibers are poor. Problems such as poor compatibility often occur when color matching with yellow dyes (Reference: Yang Xiaohong. Compatibility performance of reactive turquoise blue and reactive yellow dyeing[J]. Printing and Dyeing, 2007,33(14):18-21.)

Embodiment 1

[0049] This embodiment provides a high-sunlight emerald green pyridone reactive dye compound and a preparation method thereof. The specific steps are as follows:

[0050] (a) Chlorosulfonation reaction: slowly (within half an hour) add 0.100mol copper phthalocyanine powder to 220mL chlorosulfonic acid at 40°C, stir for 30min and then raise the temperature to 135~140°C, maintain the reaction for 3h; To 80°C, add 0.504mol thionyl chloride dropwise within 2h, then heat to 90°C and keep for 2h; after the reaction is finished, cool to room temperature, pour into ice water while stirring, precipitate out; stand still, filter, The filter cake is washed with ice water until it is neutral to obtain a copper phthalocyanine sulfonyl chloride filter cake for use;

[0051] (b) A condensation reaction: 0.101mol of cyanuric chloride and 60g of crushed ice are beaten at 0℃ for 30min; 0.100mol of 2,4-diaminobenzenesulfonic acid, dissolved in 160mL of water, and adjusted to pH 6 with 10% dilute hydr...

Embodiment 2～9

[0057] The examples respectively provide a high-sunlight emerald green pyridone reactive dye compound and a preparation method thereof, and the specific steps are similar to those in Example 1. The difference is that the 4-(β-sulfate ethylsulfone) aniline in step (f) is changed to 4-(β-sulfate ethylsulfone) aniline-2-sulfonic acid, 2-methoxy 4-(β-sulfate ethylsulfone) aniline, 2,5-dimethoxy-4-(β-sulfate ethyl sulfone) aniline, 2-amino-5-(β- Sulfate ethyl sulfone) benzoic acid, 3-(β-sulfate ethyl sulfone) aniline, 3-(β-sulfate ethyl sulfone) aniline-6-sulfonic acid, 2-methoxy 5-(β-sulfate ethyl sulfone) aniline and 2-hydroxy-5-(β-sulfate ethyl sulfone) aniline, the dosages are both 0.100 mol; after step (f), the final product The structure of the high-sunlight emerald green pyridone reactive dye compound containing copper phthalocyanine and pyridone double color body is shown in formula (I-2A) to formula (I-9A) in Table 1.

Embodiment 10～18

[0059] The examples respectively provide a high-sunlight emerald green pyridone reactive dye compound and a preparation method thereof, and the specific steps are similar to those in Example 1-9. The difference is: the 2,4-diaminobenzenesulfonic acid in step (b) is changed to m-phenylenediamine-4,6-bissulfonic acid, and the amount is both 0.100 mol; after step (f), the copper phthalide is finally obtained The structure of the high-sunlight emerald green pyridone reactive dye compound of cyanine and pyridone dual color bodies is shown in formula (I-10A) to formula (I-18A) in Table 1.

Description

Technical field [0001] The invention belongs to the technical field of dyes and their preparation, and relates to an intramolecular color-matched high-sunlight emerald green pyridone reactive dye compound containing yellow and blue dual color bodies, and a preparation method and application thereof. Background technique [0002] Reactive dyes have the characteristics of bright color, complete chromatogram, and excellent wet processing fastness. They are widely used in the dyeing and printing of cellulose fibers and protein fibers. With the improvement of people's living standards, the requirements for textile styles and colors are getting higher and higher. At present, green dyes are mostly compounded by two or three dyes. However, due to the solubility of compound dyes, the directness to fibers during dyeing, and the reactivity to alkali fixation, the stability of dyeing is poor, Easy to dye flowers, with big head-to-tail difference. For example, reactive blue dyes with phthal...
