Description

A kind of preparation method and product of modification dispersed dye diffusant
Technical field
The invention belongs to field of chemical technology, specifically relate to a kind of preparation method and product of modification dispersed dye diffusant.
Background technology
In the commercialization course of processing of dispersed dye, dispersed dye are ground into tiny particle, are conducive to it in the absorption of polyester fibre surface, are finally diffused in the inside of fiber and go, and complete whole dyeing course.And adding of dispersion agent is to be used to improve the dispersing property of such dyestuff in water, prevent in dyeing course, the phenomenons such as the crystal growth that tiny dye granule occurs in dye bath, gathering, aggegation, thus have influence on the quality of dyeing keratin-fiber.
Naphthalene is that dispersed dye diffusant belongs to naphthalene sulfonic formaldehyde condensation compound, at dispersed dye with being to belong to use to obtain the most general type disperse dye diffusant in diffusant family, naphthalene is that dispersed dye diffusant is produced and generally all be take naphthalene or methylnaphthalene and through sulfonation, hydrolysis, condensation, neutralization, desalination etc., be prepared from as raw material, in order to reduce raw materials cost, very great dispersed dye diffusant production unit all replaces naphthalene or methylnaphthalene to produce with coal tar wash oil or oil washing oil at present.
The chloro-5-phenylmethylamine-4-of CLT acid formal name used at school 2-sulfonic acid, it is a kind of important organic red pigment intermediate, on pigment industry, mainly for the production of c.I. Pigment red 52 and c.I. Pigment red 53, this pigment is widely used in paint, coating, colored ink, rubber and coloring plastic etc.CLT acid is that Year's consumption is crossed one of organic intermediate of ten thousand tons in the world.In pigment dyestuff intermediate CLT acid production process, after the hydrogenation reduction stage completes, can produce nearly 1/4 the various isomer mixtures of CLT acid, this component of mixture is more complicated, if be isolated not in time, will affect the product purity of the chloro-3-phenylmethylamine-4-of certified products 6-sulfonic acid and the coloured light of the pigment dyestuff that is later synthesized.Yet how about the various isomer mixtures of nearly 1/4 the CLT producing after separating acid are used, and make it to become the raw material in industrial production, are puzzlement researchist's difficult problems always.
The document of the report section of having CLT acid producing waste water reuse is less both at home and abroad.Publication number is that to disclose a kind of CLT acid producing waste water be that the synthetic high efficiency water reducing agent of raw material and production technique thereof comprise CLT acid producing waste water, phenol compound and solvent mixture heating for dissolving, adjust pH to the Chinese patent literature of CN102731011A; Add after aldehyde compound and auxiliary agent insulation reaction; Reaction finishes rear cooling.Above-mentioned technique is usingd the waste water of the phenyl ring class isomer mixture that CLT acid produces in producing as the raw materials for production of sulfamate high-effective water-reducing agent, on the one hand regeneration industrial waste, on the other hand, the raw materials cost of sulfamate high-effective water-reducing agent reduces approximately 30%, greatly improves the competitive power of product.
Yet the amount of the CLT acid producing waste water of annual domestic generation is very huge, only above-mentioned a kind of way of recycling is difficult to thoroughly solve the technical problem that CLT acid producing waste water reclaims.So, for reducing environmental stress, reducing enterprise's input cost, the waste water recycling mode of exploitation diversification, has great strategic importance.
Summary of the invention
The invention provides a kind of preparation method of modification dispersed dye diffusant, it is in dispersed dye diffusant production process at naphthalene that the method adopts, add the various isomer mixtures of CLT acid, make it participate in the condensation reaction of aldehyde compound, thereby produce the modification dispersed dye diffusant that price is cheaper, both reduced the production cost of modification dispersed dye diffusants, reduced again the various isomer mixtures possibility of the by product-CLT acid pollution on the environment producing in pigment dyestuff intermediate CLT acid production process, suitability for industrialized production is obtained comprehensively, the development of sustainability.
