摘要:
Novel sulfonated quinolone compounds used in the preparation of fiber reactive dyes having the formula: ##STR1## being N-alkyl substituted-4-hydroxy-6-sulfo-2-quinolone. The alkyl group bonded to the nitrogen in the quinolone has from 1 to 4 carbon atoms which may be further substituted by an hydroxy, amino, or sulfo group. The compounds of the invention may be prepared by the sulfonation of an N-alkyl substituted-4-hydroxy-2-quinolones, ##STR2## followed by selective desulfonation to yield the compounds of interest. New monoazo fiber reactive dyes having the formulas: ##STR3## and their metal complexes, may be prepared from these sulfonated compounds by the diazotization of an amine component, selected from an unsubstituted, or a substituted benzene or naphthalene compound, containing a fiber reactive group, and coupling the diazo component to the compounds of the invention. These dyes are suitable for the dyeing and printing of native and synthetic carbonamide containing fibers, and native or regenerated or synthetic hydroxy containing fibers, especially on cellulose fibrous materials, in the presence of an alkaline agent.

摘要:
A process for the preparation of isomerically pure sulfonic acids of 2-aminonaphthalenes having a fiber reactive substituent of the formula --(SO.sub.2 X) wherein X is --CH.sub.2 --CH.sub.2 --Z and Z is a substituent such as thiosulfato, phosphato or sulfato. The process comprises a first step of acylating the amino group of the substituted 2-aminonaphthalene to form a N-acyl derivative of the formula, R--CO--NH--A--SO.sub.2 X wherein A represents a naphthalene nucleus. The N-acyl derivative is then sulfonated to provide an essentially isomerically pure sulfonic acid derivative of the formula R--CO--NH--A(--SO.sub.2 X, --SO.sub.3 H). Depending upon the position of the --SO.sub.2 X group in the starting material, the sulfonation reaction product will have one of the following isomeric ring positions for the sulfonyl and sulfo groups, respectively; 5:7 or 7:5 or 6:8 or 8:6. Exemplary products are 2-acetylamino-5-(beta-sulfatoethylsulfonyl)-naphthalene-7-sulfonic acid or 2-acetylamino-7-(beta-sulfatoethylsulfonyl)-naphthalene-5-sulfonic acid or 2-acetylamino-6-(beta-sulfatoethylsulfonyl)-naphthalene-8-sulfonic acid or 2-acetylamino-8-(beta-sulfatoethylsulfonyl)-naphthalene-6-sulfonic acid. The latter aminonaphthalene sulfonic acid having 2-8-6 substitution is an important starting material for the preparation of fiber reactive dyes; the former three are not. New monoazo and disazo dyes or their metal complexes may be prepared from the 2,6,8; 2,5,7; and 2,7,5 isomers by diacylating, diazotizing and coupling them with coupling components selected from an unsubstituted or substituted benzene, naphthylene, acetoacetic acid arylide, arylamide, pyazolone or pyridone.
