Abstract
The invention discloses high sun-proof red reactive dye and the preparation method thereof. Tricyanogen chloride is unipolycondensated with m-Phenylene diamine-4,6-ortho sulfonic acid, m-Phenylene diamine-4,6-disulfonic acid or p-phenylene diamine-ortho sulfonic acid, and then copolycondensated with para position or meta position ester compound, and then diazotized and coupled with 2R acid or gamma acid; tricyanogen chloride is unipolycondensated with para position or meta position ester compound, and then copolycondensated with m-Phenylene diamine-4,6-ortho sulfonic acid, m-Phenylene diamine-4,6-disulfonic acid or p-phenylene diamine-ortho sulfonic acid, and then diazotized and coupled with 2R acid or gamma acid; the high sun-proof red reactive dye has good building up property, level dyeing property, color fixation rate and high combination stability of fiber and dye, and has good light fastness. The additive property of mixed color matching dye mixture further enhances the dying appetence and the color fixation rate, to ensure the dying effect to be more outstanding. The invention is suitable for the dying of natural cellulose such as cotton, viscose fiber and blended fiber.
Description
Technical field
The present invention relates to red reactive dyes of a kind of high light-fast and preparation method thereof.
Background technology
Along with the users of dyeing are more and more high to reactive dyestuffs requirement to its light fastness in dyeing course, yellow dyes and blue dye all have the comparatively satisfied kind of light fastness in the kind of reactive dyestuffs at present, red exactly kind can not satisfy user's demand, and pressing for dyestuff manufactory can provide light fastness red preferably kind.
Summary of the invention
In order to solve light fastness orchil kind preferably, the invention provides red reactive dyes of high light-fast and preparation method thereof.
The red reactive dyes of a kind of high light-fast of the present invention, its structure is as follows:
A
1Be C

With B
1For not isoplastic dyestuff (1) mixes colorant match, perhaps dyestuff (2) is mixed colorant match with dyestuff (3).
Its method is:, path 1: cyanuric chloride and mphenylenediamine ortho-sulfonic acid, mphenylenediamine disulfonic acid or Ursol D ortho-sulfonic acid one contract, then and contraposition or a bit esterified thing two contract diazotization and 2R acid or γ acid coupling and getting again; Can also contract by cyanuric chloride and contraposition or a bit esterified thing one, contract with mphenylenediamine ortho-sulfonic acid or mphenylenediamine disulfonic acid or Ursol D ortho-sulfonic acid two again, again diazotization and 2R acid or γ acid coupling and getting.
For the purpose of the anionic group of dyestuff of the present invention was convenient, they all existed with the sour form acid of freedom form, when existing in the water soluble salt mode when making and use, exist with sodium salt or potassium salt form especially.
The present invention goes out the orchil composition of array structure down, it is applicable to the dyeing of natural cellulose such as cotton, viscose fiber and mixed fibre, it has good enhancing and level-dyeing property, in addition, higher degree of fixation, fiber-dyestuff bonded high stability, wash resistant, fastness to light and good photostabilization are still arranged, and fastness shows Exposure to Sunlight, the sweat day light fastness of light color especially.And utilize composite technology to utilize the further painted avidity of raising of additivity and the degree of fixation of two or more dye mixture to make its Color more excellent.
Embodiment:
Specific implementation method:
Embodiment one: contract: contract in one and put 150 parts of mixture of ice and water in the bucket, add 18.5 parts of 100% cyanuric chlorides, 0 ℃ of making beating 45-60 minute down, slowly drip 26.8 parts of mphenylenediamine disulfonic acid solution of 100% then, in 0-5 ℃ of reaction 2-3 hour to terminal.
Diazonium: contracting in one adds 24 parts of industrial goods hydrochloric acid in the liquid, slowly drips 6.9 parts of sodium nitrite solutions of 100% under 0-5 ℃, finishes, and controlled temperature 0-5 ℃, the little blue colour response of starch potassium iodide paper was eliminated excessive nitrous acid with thionamic acid after 2 hours.
Coupling: 34.1 parts of 2R acid 100% are added in the diazonium salts, and it is 2-7 that the soda ash liquid with 15% is regulated PH, and controlled temperature is 0-10 ℃ simultaneously, reacts that to disappear to diazonium salt be terminal point.
Two contract: 28.1 parts with right-(beta-hydroxyethyl sulfuryl) sulfate ester aniline 100% join in the coupling solution, and to regulate PH with 15% soda ash liquid be 5.5-6.5, be warming up to 40-45 ℃ then, react 4-5 hour to terminal, two things that contract of reaching home are reduced to normal temperature, the muriate that adds 10-20% is then saltoutd, suction filtration, filter cake dry formula (2) dyestuff.
Embodiment two: change the 2R acid in the example 1 into γ acid, other condition same cases down formula (3) structure dyestuff.
Embodiment one gained dyestuff and and embodiment two gained dyestuffs can dye separately, also can be with it by 50: 50 mixed colorant match.
Claims (2)
1. the red reactive dyes of a high light-fast, its structure is as follows:
A1 is C1
B1 is
Or
A2 is C1
B2 is
M is 1 or 2
A3 is C1
B3 is
N is 1 or 2
B1 for not isoplastic dyestuff (1) mixes colorant match, is perhaps mixed colorant match with dyestuff (2) with dyestuff (3).
2. the red reactive dyes preparation method of a high light-fast is: cyanuric chloride and mphenylenediamine ortho-sulfonic acid, mphenylenediamine disulfonic acid or Ursol D ortho-sulfonic acid one contract, then and contraposition or a bit esterified thing two contract diazotization and 2R acid or γ acid coupling and getting again; Can also contract by cyanuric chloride and contraposition or a bit esterified thing one, contract with mphenylenediamine ortho-sulfonic acid or mphenylenediamine disulfonic acid or Ursol D ortho-sulfonic acid two again, again diazotization and 2R acid or γ acid coupling and getting.
