| titleOfInvention | Production of new azo dyestuffs on cellulosic materials and of intermediates therefor |
| abstract | 513,323. Dye intermediates ; dyeing and printing. SAUNDERS, K. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 1, 1938, No. 10080. [Classes 2 (iii) and 15 (ii)] Ethers of 4-amino-2:5-di-(#-hydroxyethoxy)- benzeneazophenols, of the general formula where R is alkyl, benzyl or phenyl and, together with the phenylene radicle A, may carry one or more methyl or chloro substituents, are manufactured by coupling with 2-5-di-(#- hydroxyethyl)-amiline a diazotized alkyl, benzyl or phenyl aminophenyl ether which may carry one or more methyl or chloro substituents, e.g., diazotized o-or p-aminodiphenyl ether, p - tolyl - o - aminophenol ether, 2 - amino - 4'- chloro-1:1-diphenyl ether, o- or p-aminophenyl benzyl ether, 2- or 3-amino-4-methoxytoluene, o- or p-anisidine or p-phenetidine. Diazonium compounds are manufactured by diazotizing the aminoazo compounds described above and, if desired, reacting the products with a metal salts, especially a zinc halide, e.g., zinc chloride, in order to form a double 'salt therewith. Azo dyes, forming upon the material ; printing.-Cellulosic textile materials, e.g., cotton, are dyed or printed in red shades by'coupling thereon the diazonium compounds described above with acylacetic acid arylamides, e.g., bis-acetoacetic - o - tolidide, terephthaloyl - bis - acetic-5-chloro-2:4-dimethoxyanilide or benzoylacetic-6-chloro-2:4-dimethoxyanilide. Specifications 210,217, [Class 2 (iii)], and 422,417 are referred to. |
