Abstract
The invention discloses a purple reactive dye for wool, which has the following general formula structure in specifications, wherein R1 is H, -CH3,-OCH3 or -SO3M; R2 is -H, -CH3, -OH, -NO2 or -COOH; and M is H or alkali metal. The purple reactive dye for wool has the advantages of high reactivity, excellent solubility, bright and attractive color light, low cost of required raw materials and environmental pollution reduction.
Description
Technical field
The present invention relates to active dye technical field, particularly relate to a kind of purple active dye for wool.
Background technology
Now general dyeing wool, cashmere, used dyestuff are matching stain, acid mordant dye and metallized dye.Because with the material that these kinds of dyes are dyed, fastness is all not good enough, coloured light is not really gorgeous, but also can cause trouble to environmental protection.Enter 21 century, because the restriction of environmental ecology is more and more higher for the requirement of dye uptake, degree of fixation and dyeing waste-water.Matching stain can not satisfy development of times again.
Summary of the invention
Technical problem to be solved by this invention is, provides one can reduce environmental pollution, and the desired raw material cost is low, the product solubility height, and also bright in colour, the application performance excellence, easy to use, the purple active dye for wool that suitability is strong.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of purple active dye for wool has following general structure

The present invention also provides a kind of dye composite, and it comprises the dyestuff or derivatives thereof of above-mentioned formula (I).
The present invention also provides the dyeing process of a seed hair fiber, comprises the dyestuff and the hair fibre contact procedure that make formula (I).
Dyestuff of the present invention can with the composite use of other dyestuffs, obtaining other color, or with the composite raising dyeing behavior of other dyestuff.
The dye composition of above-mentioned general formula (I) can dye to hair fibre separately or with other dyestuff is composite, and it has good dyeing behavior, and coloured light is bright-coloured, and fastness is good, and especially hair fibre has good dye uptake and degree of fixation.
Embodiment
The structure of purple active dye of the present invention is illustrated above, below will be by embodiment to work further instruction of the present invention.
Embodiment 1:
Present embodiment provides the preparation method of a kind of particular compound in formula (I) compound, and this compound is the compound as shown in the formula (II):
Concrete preparation method is as follows:
1, the dissolving of H acid
In 500 milliliters of four-hole bottles, add 200 milliliters in water, add 100%H acid 17.1 grams then, stir down and transfer pH=6.5-7, make material dissolution, clarification with 30% sodium hydroxide solution.The volume of adjusting solution is 250 milliliters.Make the concentration C %=4.5 of solution
2, condensation reaction
The outer bath adjusted H acid solution temperature to 0 ℃.0～5 ℃ of branch of holding temperature four times slowly adds 100% Tosyl chloride, 14.0 grams, 60 minutes consuming time altogether, finishes, all with 30% sodium hydroxide adjustment pH=6～6.5 at every turn.0～5 ℃ of holding temperature, it is anti-to keep pH=6～6.5, answers 3 hours.PH=8.5 is adjusted with 30% sodium hydroxide in the back, is warming up to 90 ℃, and 90～95 ℃ of holding temperatures were reacted 1 hour.Be cooled to 25 ℃, standby.
3,2-amino-5-(2 ', 3 '-dibromo propionamido)-Phenylsulfonic acid dissolving
In 500 ml beakers, add 200 milliliters in water, add 100%2-amino-5-(2 ', 3 '-dibromo propionamido)-Phenylsulfonic acid 20.1 grams then, adjust pH=7～7.5, treat the solution clarification, add 100% Sodium Nitrite, 3.5 grams, mixing with 30% sodium hydroxide.Standby.
4, diazotization reaction
In the 800ml beaker, add 200ml water, 15.2 grams, 30% hydrochloric acid soln is added.Adjust solution temperature to 5 ℃ with direct ice, adjust volume to 300ml.Guarantee the pH value less than 2 at reaction soln, under the condition of the little indigo plant of potassium iodide starch paper, 5～8 ℃ of holding temperatures slowly added the amino 5-(2 ', 3 '-dibromo propionamido) of 2--Phenylsulfonic acid solution in 1 hour consuming time.5～10 ℃ of holding temperatures were reacted 2 hours.Eliminate excessive nitrous acid with thionamic acid.
5, coupled reaction
Diazonium liquid is joined in the condensated liquid, stir.Transfer pH=7 with 96% accent yellow soda ash, be warmed up to 10 ℃, 10～15 ℃ of holding temperatures are kept pH=7～7.5, react 4 hours.
6, neutralization reaction
Coupled reaction liquid is adjusted to pH=6-6.5 with 30% hydrochloric acid soln.Stirred 15 minutes.
7, drying
The look liquid of 6 steps is joined in the feed liquid preheater, adjust 210 ℃ of spray tower inlet temperatures, carry out spraying drying with 95-100 ℃ temperature out.Get formula (II) structure purple dye 63g (100%).
The purple active dye for wool application performance of the present invention's preparation is as shown in the table:
Content according to the foregoing description, this area is easy to use the substitution of materials Tosyl chloride and/or the 2-amino-5-(2 ' of respective amount, 3 '-dibromo propionamido)-and Phenylsulfonic acid, come other compound in the preparation formula (I), so no longer describe the preparation method of other compounds herein.
The dyestuff of above-mentioned formula (II) is at the coloured fibre material, and when particularly dyeing hair fibre, it demonstrates good enhancing, level-dyeing property and detergency, and has good fastness aspect photostabilization, washing fastness, anti-floating property of chlorine and the perspiration resistance of dyeing articles.And the neutral qualified discharge of the dyeing waste-water of the prepared dyestuff of this method is easy, is beneficial to environmental protection.
Dyestuff of the present invention and dyestuff preparation method are described by specific embodiment.Those skilled in the art can use for reference links such as content appropriate change raw material of the present invention, processing condition and realize corresponding other purpose, its relevant change does not all break away from content of the present invention, all similar replacements and change will become apparent to those skilled in the art that and all be regarded as comprising within the scope of the present invention.
