Abstract
The invention provides an active lemon yellow GG dye and preparation method. The active lemon yellow GG dye is formed by coupling 1,3,5-pyrazolone and diazonium salt of ethyl sulfon sulfate aniline compound containing sulfonic group or methyl, methoxyl group, ethyl. The active lemon yellow GG dye has features of uniform painting, bright color, good fastness, less hydrolyzed dye, high fixation ratio, good washing fastness, good stability of alkali and salt proof, widely used in cotton fibre dyeing, discharge dyeing and printing.
Description
Technical field
The present invention relates to a kind of reactive lemon yellow GG dye and preparation method thereof.
Background technology
The reactive yellow 1 of late nineteen nineties invention
#, its structural formula is as follows:
Color and luster is not bright-coloured during this dyeing, fastness is poor, hydrolised dye is many, degree of fixation is not high.
Summary of the invention
The invention provides a kind of reactive lemon yellow GG dye and preparation method thereof for addressing the above problem.
A kind of reactive lemon yellow GG dye of the present invention claims C.I. reactive yellow 15 again, and its structural formula is as follows:
In the formula: (1) R=H, CH
3, OCH
3C
2H
5, OC
2H
5SO
3H etc.
(2)M＝Na、K
Active group R is for being converted into the group of vinyl among the present invention, its mixture carries out coupling by the diazonium salt of 1.3.5-pyrazolone and the ethyl sulfonyl sulfate aniline compound that contains sulfonic group or methyl, ethyl, methoxyl group etc. and makes, 0-15 ℃ of coupling temperature, PH=1.5-6.5.
The method that the present invention prepares diazonium salt compares diazonium for the little acid of ice mill.
A kind of reactive lemon yellow GG dye of the present invention and commercially available reactive yellow 1
#Deng comparing, have colouring even, good lifting force, dye yield height, depth is good, degree of fixation is high, compatibleness is good, washing performance is good, process tolerance is good, salt and alkali resistance is good, can dye and stamp, again can discharge.During its simultaneous test data are listed in the table below.
Following standard is adopted in the test of performance index in table:

Specific embodiments:
Embodiment one
(1) takes by weighing 26 parts of 1.3.5-pyrazolones of weight and add 200ml water, pulled an oar 1 hour.
(2) take by weighing the ethyl sulfonyl sulfate aniline compound that 31 parts of weight contain sulfonic group or methyl, methoxyl group, ethyl etc. and add an amount of frozen water 0 ℃ of making beating 2 hours.Add quantitative hydrochloric acid then, add 6.9 parts of inferior sodium, temperature 5-8 ℃, the blue look of control congo-red test paper, the little orchid of KI test paper, inferior sodium added afterreaction 1 hour, eliminated little excessive nitrous acid before the coupling.
(3) diazonium salt for preparing is joined in the 1.3.5-pyrazolone that is cooled to 5 ℃, slowly regulate PH=5-6.5 with sodium bicarbonate then, temperature 0-5 ℃.Keep PH=5-6.5, temperature 0-5 ℃ of reaction 3-4 hour to diazonium salt disappears.Make the green partially reactive lemon yellow GG of coloured light, claim C.I. reactive yellow 15 again.
Embodiment two
(1) takes by weighing 26 parts of 1.3.5-pyrazolones of weight and add 200ml water, pulled an oar 1 hour.
(2) take by weighing the ethyl sulfonyl sulfate aniline compound that 35 parts of weight contain sulfonic group or methyl, methoxyl group, ethyl etc. and add an amount of frozen water 0 ℃ of making beating 2 hours.Add quantitative hydrochloric acid then, add 6.9 parts of inferior sodium, temperature 5-8 ℃, the blue look of control congo-red test paper, the little orchid of KI test paper, inferior sodium added afterreaction 1 hour, eliminated little excessive nitrous acid before the coupling.
(3) diazonium salt for preparing is joined in the 1.3.5-pyrazolone that is cooled to 5 ℃, slowly regulate PH=3.5-6.5 with sodium bicarbonate then, temperature 5-15 ℃.Keep PH=3.5-6.5, temperature 5-15 ℃ of reaction 3-4 hour to diazonium salt disappears.Coupling makes the red partially reactive lemon yellow GG of coloured light, claims C.I. reactive yellow 15 again.
