Abstract
The invention belongs to the dye processing technology field, in particular to a new synthesis technology for a vat blue RSN dye. The invention utilizes a new solvent for condensation reaction, realizes one step reaction without the prior processes of refinement and oxidation, and obtains high purity vat blue RSN raw dye with high yield; the yield of the prior technology only reaches 70 percent, while the yield of the new technology with one step condensation reaction can reach over 90 percent, which not only greatly reduces production cost and improves product quality, but also tremendously reduces pollution and emission of three wastes.
Description
Technical field
The invention belongs to the dyestuff processing technique field, particularly a kind of Vat Blue RSN dyestuff new synthetic process.
Background technology
At present in the dyestuff processing industry, its traditional processing technology is: condensation reaction: the 1-aminoanthraquinone, dimethyl sulfoxide (DMSO) is in the condensation still, through dissolving, heat up, the hydro-oxidation potassium solution, condensation reaction is carried out in insulation and atmospheric oxidation, dilution then, oxidation, filter-press water-washing obtains the former dyestuff of crude product Vat Blue RSN, refining reaction: the former dyestuff of crude product Vat Blue RSN is through making beating, add alkali, add vat powder, refining reaction is carried out in insulation, press filtration then, washing obtains refining former dyestuff, oxidation, acid is boiled: refining former dyestuff is through making beating, oxidation, acidification reaction, press filtration then, washing, blowing obtains the former dyestuff filter cake of Vat Blue RSN.The problem that traditional technology exists: 1, dimethyl sulfoxide (DMSO) is as the condensation solvent, and the reaction mass condensation is incomplete, and the former dye strength of generation is low, yield is low, production cost is high; 2, the condensation reaction still is little, and batch charging coefficient is low, and efficient is low, single batch amount is few; 3, the assorted dyestuff of refining step generation is many, and three-waste pollution is big; 4, reaction time long, facility investment is many, the running cost height; 5, the solvent dimethyl sulfoxide (DMSO) rate of recovery is low.
Summary of the invention

The present invention realizes with following technical scheme: a kind of synthetic process of vat blue RSN, with the 1-aminoanthraquinone is raw material, at a kind of synthetic solvent (1,3-dimethyl-2-imidazolone 1,3-Dimethyl-2-imidazolidinone, DMI) in, alkaline condition exists down, with quaternary ammonium salt series is that phase-transfer catalyst carries out condensation, dilution, filtration and obtains the former dyestuff filter cake of Vat Blue RSN, it is characterized in that: described condensation reaction is the application in synthetic solvent DMI, is that raw material carries out condensation reaction in solvent DMI with the 1-aminoanthraquinone;
(1) described proportioning raw materials weight part: DMI usage quantity (in 1-aminoanthraquinone weight), be generally 0.5-5 part, the best is 1-3 part;
(2) alkaline condensing agent used in the present invention, potassium hydroxide or sodium hydroxide, wherein potassium hydroxide is more suitable, can be the solid or the aqueous solution, consumption (in 1-aminoanthraquinone weight): be 0.2-5 part, the best is 0.5-2 part;
(3) catalyzer used in the present invention is quaternary ammonium salt series phase-transfer catalyst, and consumption is (in a 1-aminoanthraquinone weight): the best is 0.1%-0.5%;
(4) 1-aminoanthraquinone used in the present invention is a powdery, and content is more than 〉=90%, also available wet cake.
Described synthetic process of vat blue RSN, setting-up point are 70-160 ℃.
Described synthetic process of vat blue RSN, former dyestuff drying after additive compound, sand milling, stdn makes commercial dye.
Advantage of the present invention is: the present invention utilizes novel dissolvent to carry out condensation reaction, the energy single step reaction is refining without traditional technology, the process of oxidation, obtain the former dyestuff of highly purified Vat Blue RSN with high yield, the yield of traditional technology can only reach 70%, this technology one step condensation reaction yield can reach more than 90%, not only greatly reduce former dyestuff production cost, improved quality product, and greatly reduced the pollution and the discharging of the three wastes.
