Abstract
The present invention relates to active red SBE monomer which belongs to the field of dye. Cyanuric chloride and a dispersing agent are pulped into a powder shape under the existence of crushed ice, a dry product, p (beta-sulfuric ester ethyl sulfone)aniline, of which the proportion is from 1 to 1.5 is added in for one-time condensation, a pH value is controlled to be from 2 to 4, a temperature is from 6 to 12 DEG C, a dry product, H acid is added in for secondary condensation after reaction is finished, the temperature is controlled to be from 25 to 35 DEG C, the pH value is controlled to be from 3 to 5, the temperature is dropped to 20 to 30 DEG C after the reaction is finished, and the reaction substance is in the diazonium salt coupling with a dry product, 1, 5-disulfonate-2-naphthylamine; after the coupling is finished, the coupling substance is directly sprayed dryly. The process of the present invention reduces production cost, improves production efficiency, and reaches the production requirements of cleanness; simultaneously, the quality of the product fully approaches to that of red M-3BE., and the force proportion and the dissolvability are better than those of the red M-3BE.
Description
Technical field
The present invention relates to dye field, be meant a kind of reactive red monomer and synthetic this reactive red monomer methods, the composite active red dye that to provide with this reactive red monomer simultaneously be major ingredient.
Technical background
The H acid solution and the cyanuric chloride one of existing red M-3BE employing 10～20% contract, with solution 1,5-disulfonic acid-2-naphthylamines carries out the diazonium salt coupling then, and the sodium-chlor of adding 10～20% is saltoutd, filtering separation, filter cake is pulled an oar into solution, again and content be that 20～30% position ester solutions carry out the secondary condensation, saltout drying and get, this unit cost height that mixes the technology acquisition by synthetic, press filtration, oven dry, pulverizing, assembly, Dry Sack is dark inadequately, and the whole production process complexity, and sewage is many.
Summary of the invention
The invention provides a kind of with position ester synthetic reactive red monomer between the para-ester replacement, by adopting the dry product synthesis technique, reach cleaner production, the product of acquisition has lovely luster, gets color depth, solubleness height, advantages such as substantivity is low, compatibleness good, favorable reproducibility, excellent levelling property, enhancing rate height, degree of fixation height, easily washing property is good, colour fastness is good.The monomeric structural formula of this reactive red SBE is:
Synthetic this reactive red SBE monomer methods is: cyanuric chloride and dispersion agent are pulled an oar in the presence of trash ice to Powdered, the dry product that adds proportioning and be 1-1.05 is to (beta-sulfuric ester ethyl sulfonyl) aniline primary condensation, control pH value 2～4,6～12 ℃ of temperature add the condensation of dry product H acid secondary, 25～35 ℃ of controlled temperature again after reaction is finished, control pH value 3～5, reaction finishes to be cooled to 20～30 ℃ and dry product 1, and 5-disulfonic acid-2-naphthylamines carries out the diazonium salt coupling, and coupling finishes directly spray and does.
Position ester between replacing with para-ester in this synthetic method, other raw materials are constant, and reduce its proportioning, adopt dry product to feed intake simultaneously, and the hydrochloric acid that consume when having reduced used liquid caustic soda of material dissolution and reaction reduce unit cost and reach 40～50% more; Dry product feeds intake, and has also reduced the consumption of water, has improved the solid content of material, has improved spray-dired efficient, has reduced the consumption of heat energy and electric energy.This technology has reduced production cost, has improved production efficiency, reaches to clean production requirement, and quality product near red M-3BE, also is better than red M-3BE comprehensively on power part and solubleness simultaneously.
Composite active red dye, it is a major ingredient with above-mentioned reactive red SBE monomer, weight consists of: reactive red SBE monomer 80～95%, dust-proofing agent 1～5%, solubility promoter 1～15%.
The SBE reactive red is brought up to about 180% through this explained hereafter intensity, and solubleness reaches 180 grams per liters, and light fastness reaches 5 grades, 4 grades of soaping fastnesses, crock fastness 4-5 level, ironing fastness 4-5 level; Simple and the cleaning of synthesis technique, sewage reduces more than 99.5%, feeds intake by dry product; the directly dried yield that increases product of spray of not saltouing, unit must be measured by 100 kilograms and bring up to 170 kilograms, compare with traditional technology; reach the joint consumption and fallen this, improved the purpose of dyestuff quality and environment protection.
