Abstract

281,713. Soc. of Chemical Industry in Basle. Dec. 4, 1926, [Convention date]. Samples furnished. Azo dyes yielding on animal fibres yellow even shades fast to light are obtained by coupling a 2 : 4-diaminobenzene-1-sulphonic acid, acidylated in the 4 position, or a nuclear substitution derivative thereof, with a pyrazolone. The acidyl group mav be derived from formic, acetic, an arylcarboxylic, an arylsulphonic, carbonic, oxalic, or phthalic acid, or from a carbonic acid ester, and in the case of a dibasic group may be combined with one or two molecules of the diamine. In examples, the following dyestuffs are specified :-2-amino-4-acetylamino-1-benzene-sulphonic acid or 5-methyl (or chloro)-2-amino-4-acetylamino-1-benzene-sulphonic acid # (4<1>-sulpho, or 4<1>-sulpho-2<1>-methyl, or 4<1>-sulpho-2<1>-methyl- 6<1> - halogen) - phenyl-3-carboxy-5-pyrazolone ; 2- amino - 4-acetylamino-1-benzene-sulphonic acid # 1 - (5<1> - sulpho-2<1>-chloro)-phenyl-3-methyl-5- pyrazolone or the pyrazolone obtainable from the hydrazine derived from 1-amino-2-p-toluenesulphone-5-benzene-sulphonic acid and acetoacetic ester. Other specified pyrazolones are those obtained bv condensing hydrazine itself or the hydrazines from aniline, 2-chlor-aniline, otoluidine. m- and p-xylidines, or their sulphonic acids with acetoacetic or oxalacetic ester. Specification 9968/10 is referred to. Acidyl derivatives of 2:4-phenylenediamine-1- sulphonic acid are prepared by acidylating in the 4 - position 2 : 4-phenylenediamine-1-sulphonic acid with, for example, acetic or phthalic anhydride, chloroformic ester, acetyl or benzoyl chloride, phosgene, terephthalic acid choride or p-toluene-sulphone-chloride. 5-Methyl-4-acetylamino-2-amino-1-benzenesulphonic acid is thus obtained from 1-methyl-2 : 4-diaminobenzene by sulphonating and acetylating, 5-chloro-4-acetylamino-2-amino-1-benzenesulphonic acid by sulphonating 2 : 4-diamino-1-chlorobenzene and acetylating and 3<1>-amino-4<1>-sulphophenyl-ptoluenesulphonamide from 2: 4-phenylenediamine-1-sulphonic acid and p-toluenesulphonchloride.
