Abstract
An ethyl dispersion pigment containing cyanoxethyl is made from diazocomposition of benzene ring or heterocyclic ring amine, -H-CH3 and -CH-C2H5. The process for preparing the pigment includes diazotizing diazomposition, reacting on diazotized material with coupling composition to produce dispersion pigment. The produced pigment can be single structure and also can be synthetized directly to be mixed structure or reprepared to be mixed structure when it is sold as commodity with colours from red orange to blue.
Description
Technical field
The present invention relates to that a class contains β-cyanogen ethoxyethyl group azo type disperse dyes and composition thereof, preparation method and purposes in the fine chemistry industry.
Background technology
Common dispersed dye can be used for dying trevira, tynex and cellulose acetate, but most of dispersed dye can not dye dark color.And the dispersed dye that dye trevira only are applicable to that weak acid dyes in bathing.
Once describe a type disperse dye in the European patent EP 0136619, connecting β-cyanogen ethoxyethyl group on the coupling component nitrogen-atoms in its azoic dyestuff, also connecting a cyanoethyl simultaneously.The dyestuff that has is written among " Colour Index " (Color Index), for example:
The structural formula of C.I.Disperse Orange 80 is:
The structural formula of C.I.Disperse Red 169 is:
Shortcomings such as the dispersed dye of above-mentioned two structures exist dyeing speed slow when dying trevira, and dye uptake is low, and dyeing behavior is not good.
Along with the development of dyestuffs industries and the progress of staining technique, the confirmation trevira dyes in alkali bath and has plurality of advantages.How to develop the dispersed dye that a class had both contained cyanogen ethoxyethyl group structure, this dyestuff can be dyeed in alkali bath again, obtain the dark dense effect of dyeing, become the problem that people pay close attention to.
Summary of the invention
Azo type disperse dyes of the present invention is the dyestuff that connects β-cyanogen ethoxyethyl group structure on coupling component nitrogen-atoms, and the general structure of these dispersed dye is:
In the formula: A is a diazo component, is selected from (a) 3-amino-5-nitro-2,1-benzene a pair of horses going side by side isothiazole;
(b) 2-amino-6,7 (5)-dichlorobenzene a pair of horses going side by side thiazole;
(c) 2-chloro-4-nitro-6-bromaniline;
(d) 2-chloro-4-N-methyl-p-nitroaniline;
(e) 4-N-methyl-p-nitroaniline;

The preparation method of azo type disperse dyes of the present invention divides two kinds:
When (1) diazo component A is (a) and (b), (c), earlier the Sodium Nitrite and 93% vitriol oil are made nitrosyl sulfuric acid, diazo component is added drop-wise to carries out diazotization reaction in the nitrosyl sulfuric acid then, make diazonium solution, last and coupling component carries out coupled reaction, makes dispersed dye.Coupling component: diazo component: the mol ratio of Sodium Nitrite is 1: 1: 1.05.Concrete preparation method is:
At first Sodium Nitrite slowly is added in 93% sulfuric acid under 0-20 ℃ of stirring, is warming up to 60-70 ℃, be incubated 1 hour, after the cooling, slowly add the diazo component (a) and (b) or (c) time, insulation reaction 3 hours makes diazonium solution.The coupling component that will contain the cyanogen ethoxyethyl group again is dissolved in 93% sulfuric acid and the frozen water, under 0-5 ℃ of stirring, the diazonium drop is added in the coupling component, be reacted to the diazo component disappearance and be terminal point (detecting control) with the thin plate chromatography, filter, filter also is washed to neutrality, oven dry, makes dispersed dye, yield: 80-96%.
The thin plate that the thin plate chromatography is used is the aluminum silica gel coating, and developping agent is a toluene: acetone: sherwood oil: methyl alcohol=7: 1: 1: 1 (volume ratio).
Present method can also be with identical or different diazo component and R
1, R
2The coupling component of different substituents according to identical mol ratio with the coupling component of diazo component and above-mentioned synthesis condition, makes the mixed type dispersed dye simultaneously; Or,, make the mixed type dispersed dye simultaneously by identical mol ratio with under above-mentioned synthesis condition with the diazo component of same coupling component and different structure.
(2) diazo component A is (d) or (e) time, diazo component under agitation is added in the solution of 31% hydrochloric acid and water, is warming up to 60-65 ℃, pulled an oar 1-2 hour, and reduced to then below 0 ℃, add trash ice and add sodium nitrite in aqueous solution rapidly, 0-5 ℃ of reaction 1-2 hour, obtain diazonium liquid.Simultaneously equimolar coupling component N-ethyl-N-(β-cyanogen ethoxyethyl group) meta-aminotoluene is dissolved in 31% hydrochloric acid and water wiring solution-forming, the diazonium drop is added in the coupling solution, carry out coupled reaction at 5-10 ℃, up to detecting the diazo component disappearance with thin chromatography is reaction end, filter, filter and wash with water neutral, drain, dry, make dispersed dye, yield 90-95%.
Among this preparation method, diazo component: coupling component: the mol ratio of Sodium Nitrite is 1: 1: 1.02.Present method also can be with same diazo component and R
1Identical, R
2Difference or R
1Different R
2Identical substituent coupling component is by being equal to the dispersed dye that mol ratio and above-mentioned synthesis condition make mixed structure simultaneously.
Therefore, the dispersed dye product can be a single structure, also can be the mixture of many dyestuffs.Composite dye can be the composite of homogencous dyes, also can directly synthesize mixing colouring agent commercialization processing again.
Dispersed dye of the present invention have significantly improved the dyestuff performance of trevira, and dyeing speed is fast, the 120 ℃ of dark colors that just can dye satisfiedly.Therefore, this series dispersed dye dye uptake height, repeatability is good, particularly in the dye bath of pH=4.5-11.0 acid-to-alkaline, dye trevira, can obtain dark dense effect and identical coloration result, common dispersed dye dye trevira and only are applicable to that weak acid dyes in bathing, dyeing temperature needs 130 ℃, most of dispersed dye can not dye dark color, and that dispersed dye of the present invention get color depth is dense, and coloured light is pure, can obtain the ruddiness orange to blue, the dyestuff with good fastness and dyeing behavior is provided for basic dyeing technology.Except that dying trevira, also be suitable for dying polymeric amide and cellulose acetate, also can be used for the dyeing of ultra-fine fibre and BLENDED FABRIC, have broad use range.
Dispersed dye of the present invention mix with dispersing agent NNO, MF or sodium lignosulfonate and carry out sand milling, obtain commercial dye after the drying.Preferably with mixing diffusant.
Dying the method for trevira in the alkali bath, is to add pure water, commercialization dyestuff and alkaline reagents in dye vat, the pH=11.0 of dissolving back dye bath, add polyester textile, airtight, dyeing is warming up to 125 ℃, is incubated 30 minutes, DYED FABRICS is taken out in cooling, soaps, washes, dries.
