DISODIUM SALTS OF 4-SULFOXYETHYLSULFONYL-2-X-2'-Y-4'-AMINO-N- METHYLSULFO-N-2''-(4''-CHLORO-6''-AMINO-DI-(BETA-HYDROXYETHYL)- 1'',3'',5''-TRIAZINYL)-AZOBENZENE FOR STAINING AND PRINTING MATERIAL OF NATURAL AND/OR SYNTHETICAL FIBERS Russian patent published in 1996 - IPC

Abstract RU 2064949 C1

FIELD: organic chemistry, dyes. SUBSTANCE: product: disodium salts of 4-sulfoxyethylsulfonyl-2-X-2'-Y-4'-amino-N- methylsulfo-N-2''-(4''-chloro-6''-amino-di-(beta-hydroxyethyl)- 1'',3'',5''-triazinyl)-azobenzene where: X - H, 2-x-2′-y-4, X - H, 2′′ is synthesized by coupling preliminary diazotized 4-beta-sulfoxyethylaniline with 4-sulfoxydimethylaniline followed by interaction with cyanur chloride and reaction product amination. Synthesized dyes were used for staining and printing material prepared of cotton, dacron, cotton-dacron, caprone and wool fibers. EFFECT: high resistance of dye to physico-chemical factors. 4 tbl
