Abstract
The present invention relates to active light yellow SGE dye which belongs to the dye field. The present invention is formed by that 2.4-diaminophenylsulfonate is in the condensation reaction with cyanuric chloride at 0 to 5 DEG C, and a condensation substance is diazotized with hydrochloric acid and sodium nitrite, is coupled with N-ethyl-3-formamido-4-methyl-6-hydroxy-2-pyridone, and then reacts with p-(beta-sulfuric ester ethyl sulfone)aniline for secondary contraction. The standard quantity of the 0.1 kmol material is from 150 to 200KG, the maximum absorption wavelength is discovered to be 440 nm from chromatogram analysis, a K/S value is 16.4 is 9 to 10 times of that of light yellow K-6G under the same condition, and simultaneously, the dissolvability is 2 times higher than that of the light yellow K-6G. Thereby, the present invention can show better printing and dyeing superiority than that of the active light yellow K-6G.
Description
Technical field
The present invention relates to dye field, refer in particular to a kind of active light yellow dye, the synthetic method of this dyestuff is provided simultaneously.
Technical background
The production process of tradition reactive brilliant yellow K-6G is: 2,4-diamino benzene sulfonic acid sodium and cyanuric chloride condensation, condenses and hydrochloric acid, nitrite natrium carry out after the diazonium and 1-(2,5 two chloro-4-sulphenyls) 3-methyl-5 pyrazolone carries out coupling, contract with m-sulfanilic acid two after the coupling, extract filter cake oven dry, pulverizing and stdn of salt forms, and its 0.1Kmol material standard must be measured and be 100-120KG.This product solubility 100g/l, the pad dyeing cloth of 10g/l, 6 grades of quality index light fastness, soaping fastness 4-5 level, 4 grades of dry fastnesses, 4 grades of fastness to perspirations find that by stratographic analysis its maximum absorption wavelength is 410nm, the K/S value is 1.76 etc.
Summary of the invention
The invention provides a kind of new active bright yellow SGE dye, be at present dyeing to high strength, the high-dissolvability of reactive dyestuffs, can dye dark color and cleaner production and the kind researched and developed, major advantage is that solubleness is issued to 200g/l with condition, the pad dyeing cloth of 10g/l, find that by stratographic analysis its maximum absorption wavelength is 440nm, the K/S value is reached for 16.4, and far above light yellow K-6G, other fastness are identical.
The structural formula of this reactive brilliant yellow is:
The synthetic method of active bright yellow SGE is: 2,4-diamino benzene sulfonic acid sodium and cyanuric chloride are 0-5 ℃ of condensation reaction, condenses and hydrochloric acid, Sodium Nitrite carry out carrying out coupling with N-ethyl-3-formamido group-4-methyl-6-hydroxyl-2-pyridone after the diazonium, after the coupling with to (beta-sulfuric ester ethyl sulfonyl) aniline two reaction of contracting.
The mole proportioning of each material is: 2, and 4-diamino benzene sulfonic acid sodium: cyanuric chloride: hydrochloric acid: Sodium Nitrite: N-ethyl-3-formamido group-4-methyl-6-hydroxyl-2-pyridone: to (beta-sulfuric ester ethyl sulfonyl) aniline=1-1.1: 1-1.1: 2.5-3: 1-1.1: 1-1.1: 1-1.1.
Two after contracting product directly spraying drying get finished product, also can two contract the reaction back add two contract the sodium-chlor of the long-pending 10-30% of object or Repone K dry powder salt extract the filter cake oven dry, pulverize stdn and form light yellow SGE.
Adopt N-ethyl-3-formamido group-4-methyl-6-hydroxyl-2-pyridone to replace 1-(2 in the synthesis technique, 5 two chloro-, 4 sulphenyls) 3-methyl-5 pyrazolone component carries out coupling, contract with replacing m-sulfanilic acid to carry out two to (beta-sulfuric ester ethyl sulfonyl) aniline, other processing parameters and condition are identical, its 0.1Kmol material standard must be measured and be 150-200KG, under other situations identical in quality, find that by stratographic analysis its maximum absorption wavelength is 440nm, the K/S value is 16.4, be 9-10 times with light yellow K-6G under the condition, high 2 times of solubleness etc. simultaneously shows the light yellow K-6G of the specific activity superiority of better printing and dyeing.
