| titleOfInvention | The method of producing carbazole dyes |
| abstract | The method of producing carbazole dyesnwith the formulas 1,2 or 3, where R is a rectangle57)na linear or branched alkyl group with 1-5 atomsncarbon, optionally substituted with halogens, Arndenotes a naphthyl group substituted with hydroxyl groups,namine, sulfonic and / or sulfonate,nand M is a substituted naphthylene bridgenhydroxyl, amino, sulfo groupsnand / or sulfomanic compounds, from carbazole and derivativesnnaphthalene, characterized in that carbazole is of carbocene originnsurrenders in an aqueous solutionnalkylation reactions with compounds of Formula 4 wherein R hasnthe same as in formulas 12 and 3 and X isnhalogen, catalyzed by quaternary basesnammonium compounds generated in situ in solutionnwater with quaternary ammonium salts byntreatment with alkali metal hydroxides, thennthe resulting N-substituted carbazole derivative of formulan5, wherein R has the same meaning as in the formulasn1, 2 1 3, treated with nitric acid innacetic acid, releases the resulting nitrocarbazoles onformulas 6 or 7, in which R has the same meaningnas in formulas I, 2 and 3 and subjects them in a known mannernreduction to amines of formulas 8 or 9, wherein R has suchnthe same meaning as in the formulas 1.21 3, then these aminesnis diazotized and coupled with naphthalene derivatives of formula 10nwith R1 to Rs, where at least one ofnR1, R2, and R8 are hydroxy ornamine and the rest are hydrogen atoms, whilenR3 and R4 are sulfo or sulfonate groupsnor hydrogen atoms. |
