Embodiment 1

[0025] Example 1: 1 mole of sulfonated para-ester was reacted with hydrochloric acid and sodium nitrite at a temperature of 0 to 10°C to obtain a diazonium salt, and the diazonium salt was mixed with 0.5 mole of J acid and 0.5 mole of sulfonated methyl The mixed solution of J acid sodium salt is subjected to a coupling at 5-15° C. under acidic conditions to obtain a coupled material.

[0026] 1 mole of 2-methoxy-5-methyl-p-beta-sulfate ethyl sulfone aniline is reacted with hydrochloric acid and sodium nitrite at a temperature of 0-5°C to obtain a diazonium salt. The diazonium salt and the above-mentioned coupling material are subjected to secondary coupling at a temperature of 8-15° C. and a pH of 5.5-7.5. After concentration by nanofiltration and spray drying, the structural components of formula I and formula II (deep red original powder) are obtained.

[0032] Example 3 1 mole of sulfonated para-ester was subjected to diazonium reaction with hydrochloric acid and sodium nitrite at a temperature of 0-10°C to obtain a diazonium salt. Diazonium salt and 1.0 mole sulfonated methyl J acid solution 5 ~ 15 ℃, carry out a coupling under acidic conditions, and then use 1.01 mole 2-methoxy-5-methyl-p-β-sulfate ethyl sulfone aniline Hydrochloric acid and sodium nitrite undergo diazonium reaction at a temperature of 0-5°C. The prepared diazonium salt is subjected to secondary coupling with the above-mentioned coupling material at a temperature of 8-15° C. and a pH of 5.5-7.5. After concentration and spray drying, the structural component of formula I (deep red powder 1) is obtained.

Abstract

The invention discloses a novel composite active cardinal dye and a manufacturing method thereof. The composite active cardinal dye mainly comprises structural components shown in formula I, formula II and formula III, wherein the weight ratio of the structural components shown in formula I, formula II and formula III is (30-40): (30-40): (5-25). The dye disclosed by the invention can be used fordip dyeing, continuous pad dyeing and printing processes at 50-60 DEG C, and can be also used for cold pad batch dyeing; the dye has good color tone controllability, good dyeing build-up properties, high product solubility and good color fastness to chlorinated water; and the product performance of the dye is superior to that of the traditional active cardinal dye. Formula I, formula II and formula III are shown in the specification.

Description

technical field [0001] The invention belongs to the technical field of dyes, and relates to a novel composite reactive crimson dye and a manufacturing method thereof. Background technique [0002] Traditional reactive deep red S-B generally uses C.I reactive red 239, which is compounded with deep red. The dye has strong reactivity and good deep dyeing performance, but it cannot dye redder and brighter colors. For dyeing, not for printing. The invention is a new type of composite crimson dye developed for the current printing and dyeing industry with high strength, high solubility, deep color dyeing, bright shade, good dyeing controllability, and the requirements of clean production, energy saving and emission reduction. Contents of the invention [0003] The purpose of the present invention is to provide a novel composite reactive crimson with high solubility, especially low temperature solubility, good chlorine immersion fastness, moderate reactivity, low directness and ...
