Abstract
24,487. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. Oct. 25. Monoazo dyes are obtained by combining the diazo compounds of aminodiarylethers or homologues or substitution products thereof with pyrazolone sulphonic acids, or by combining the diazo compounds of sulphonic acids of these ethers with pyrazolones, pyrazolone sulphonic acids, or naphthylpyrazolone sulphonic acids. The following components are specified :-o- and p-aminophenyletber, o-aminophenyl-o-, -m-, and -p-tolylether, p-aminophenyl-m- and -p-tolylether, o-amino-pchlordiphenylether sulphonic acid, 2-aminophenylo-tolylether-4-sulphonic acid, and 4-aminodiphenylether-2-sulphonic acid ; 1-p-sulphophenyl-3-methyl- 5-pyrazolone, 1-o-tolyl-3-methyl-5-pyrazolone, 1-#- naphtbyl-4 : 8-disulphonic acid -3-methyl-5-pyrazolone, 3-methyl-5-pyrazolone. Specification 11,866/08 is referred to. The products dye wool yellow to orange shades in acid baths. o-Amino-p-chlordiphenylether sulphonic acid is obtained by reducing and then sulphonating the condensation product obtained from 1 : 4-dichlor- 2-nitrobenzene and phenol. 2-Aminophenyl-o-tolylether-4-sulphonic acid is obtained by reducing the condensation product obtained from 2-nitrochlorbenzene-4-sulphonic acid and o-cresol.
