| titleOfInvention | The method of obtaining reactive monoazo violet of s-triazine derivative |
| abstract | Method of obtaining monoazo violet reactionns-triazine derivative of the general formulanshown in the figure, consisting in enteringnfor a suspension of diazotized 2-aminophenol-4- acidn1-amino-8-naphthol-3,6-disulfonic acid sulfonic acidnand urea and after homogenizing the mixture to alkalizengradually adding ammonia waternto a pH above 9.0 and maintaining the temperaturenbelow 10 ° C and stirring until coupling is complete, afternwhat about adding to the resulting monoazo dye,ncrystalline copper sulfate and heatingnreaction mixture at 30-40 ° C, anthen on condensation of the formed copper complexnwith cyanuric chloride and on the secondaryncondensation of the obtained di-dihydrogen s-triazine withnwith ammonia, according to patent no. 162 611, characterized bynwith the reaction mixture obtained in secondaryncondensation containing a solution of reactive violet,ntreated with 30-40% hydroxide solutionnsodium salt in an amount of 4 moles per mole of the starting acidn1-amino-8-naphthol-3,6-disulfonic acid reactionnis carried out with continuous stirring at a temperature of 40 -n50 ° C to obtain a dye solution with a pH of 7.5 - 8.5,nthen the final product is directly stabilized,ndrying and standardization, and stabilizationnand / or drying and / or standardization can be carried outnsimultaneously. |
