Abstract
A manufacture method for new texture monoazo-dispersed dye, belongs to the even manufacture method of dying dispersed dye of list for polyster fibre and blended fabric dyeing and cellulose acetate and Dyeing Polyamide Fibre.This manufacture method synthesis step is few, simple to operate, and energy consumption is little, and cost is low, and yield high (reaching more than 85%) is bright-coloured through hyperchromatic fabric coloured light, has good wet colour fastness and light fastness, can replace disperse yellow brown S-2RFL.
Description
The invention belongs to the manufacture method of azo type disperse dyes, especially for the manufacture method of the monoazo-dispersed dye of polyster fibre and blended fabric dyeing and cellulose acetate and Dyeing Polyamide Fibre.
For a long time, as the disperse yellow brown S-2RFL of one of Monoazo type dispersed dye, (CI Dispeser Orange 30) (Dispeser yellow Brown S-2RFL), because synthesis procedure is long, step many (starting to need five steps to react by aniline), the shortcomings such as difficult grinding, make this DYE PRODUCTION cost high, cycle is long, energy consumption large (see Japanese Patent clear and 58160356).Germany patent Ger222S451 has introduced the manufacture method that a kind of naphthols is Monoazo type dispersed dye, but because its diazo component adopting is all the anils with electron-donating group, makes the application performance of this dyestuff not good, there is no practical value.
The invention provides a kind of manufacture method of new texture monoazo-dispersed dye, fundamentally overcome the shortcoming of prior art, can replace disperse yellow brown S-2RFL, for the dyeing of polyster fibre and BLENDED FABRIC thereof.
Structure according to the new texture monoazo-dispersed dye of the inventive method manufacture is:

Coupling component of the present invention adopts beta naphthal or its acetyl derivatives; diazo component adopts the anils with strong electron-withdrawing group group; it is 2.4-dinitrobenzene-6-bromaniline diazonium salt; or the chloro-4-nitro-diazonium salt of aniline of 2.6-bis-, the two coupling under certain condition and the organic dye compound of a kind of new texture that so far there are no in the document that makes.Its technical process is:
。
Its chemical equation: (taking the bromo-aniline of 2.4-dinitrobenzene-6-as example)
(1) add acylating agent:
(2) do not add acylating agent:
The present invention is achieved in that beta naphthal is dissolved in acetum, at 50 DEG C～120 DEG C, drip acylating agent (as aceticanhydride) and carry out acetylize, being faint yellow until solution pours in frozen water when transparent, at 0 DEG C～30 DEG C, within the scope of preferably 8 DEG C～15 DEG C, slowly dripping the bromo-diazonium salt of aniline of 2.4-dinitrobenzene-6-to reaction end (checks to ooze to enclose, diazonium salt is micro-excessive), continue insulated and stirred 30 minutes, then be washed to neutrality, filter to obtain paste, in paste: anion surfactant=1: 2 ratio, add anion surfactant (as ME, dispersing agent MF, sulfonated lignin) grind, finally at 150 DEG C～180 DEG C, spraying is dry, obtain a kind of new texture monoazo-dispersed dye.When use, can adopt hot melt process or high temperature and high pressure method to dye polyster fibre and BLENDED FABRIC obtains bright-coloured yellowish brown.
The present invention also can be directly directly presses above-mentioned technical process coupling with diazonium salt with beta naphthal or its acetyl derivatives.
Diazonium salt is to adopt conventional diazotisation methods preparation, carries out diazotization obtain diazonium salt by anils in sulfuric acid medium with Sodium Nitrite.
Embodiment: take beta naphthal 14.2 parts (0.1mol) and be dissolved in aceticanhydride solution, at 50 DEG C～120 DEG C, drip aceticanhydride, being faint yellow until solution pours in the frozen water of 200～350ml when transparent, within the scope of 8 DEG C～15 DEG C, slowly drip the bromo-diazonium salt of aniline of 2.4-dinitrobenzene-6-until reaction end, continue insulated and stirred 30 minutes, then be washed to neutrality, filter to obtain paste, by paste: anion surfactant=1: 2 add anion surfactant to grind, reach after 4～5 grades of diffustivitys, dye polyster fibre and BLENDED FABRIC obtains bright-coloured yellowish brown by hot melt process.（R

In the time not adding acylating agent, the dyestuff obtaining is R

The advantages such as it is few that the present invention has synthesis step, simple to operate, and energy consumption is little, and cost is low, yield high (reaching more than 85%), bright-coloured through hyperchromatic fabric coloured light, also there is good wet colour fastness and light fastness.
Claims (6)
