Abstract
Monoacidyldiaminodiarylsulphones are obtained by treating with acidylating agents diaminodiarylsulphones derived from phenylene- or naphthylene-diamines. According to examples, the following derivatives are obtained using acetic acid, acetic anhydride, benzoyl chloride or phthalic anhydride as acidylating agent in the presence of a solvent such as alcohol, ethyl acetate, or diluted acetic acid:-monoacetyl- or monobenzoyl-2 : 5 -diaminobenzene-1-p-toluenesulphone, the monophthalamic acid of 2 : 5 - diaminobenzene-1-p-toluenesulphone, monoacetyl - 2 : 5 - diaminobenzene-1-p-chlorobenzenesulphone, the monophthalamic acid of 2 : 5 - diaminobenzene 1 -p-chlorbenzenesulphone, monoacetyl - 2 : 4 - diaminobenzene-1-p-toluenesulphone, and monoacetyl - 1 : 4 - naphthylenediamine-2-p-toluenesulphone; the anils corresponding with the two -phthalamic acids are also described. 2 : 4 - Diaminobenzene-1-p-toluenesulphone is made by condensing 2 : 4 - dinitrochlorbenzene with p-toluenesulphinic acid and reducing. Azodyes are obtained by diazotizing the above monoacidyl derivatives and coupling in acid solution with b -naphthylamine or a derivative or substitution product thereof. Monoazo dyes are specified from monoacetyl-2 : 5 - diaminobenzene-1-p-toluenesulphone and 2-aminonaphthalene-6-sulphonic acid or 2 : 8 : 6-acid or phenyl - 2 : 8 : 6 - acid; monoethylcarboxy - 2 : 5 - diaminobenzene-1-p-toluenesulphone and 2 : 8 : 6-acid; monobenzoyl - 2 : 5 - diaminobenzene - 1-p-toluenesulphone and 2 : 8 : 6 - acid; the monophthalamic acid of 2 : 5 - diaminobenzene-1-p-toluenesulphone and 2 : 8 : 6 - acid or phenyl - 2 : 8 : 6 - acid; monoacetyl - 2 : 5 - diaminobenzene - 1-p-chlorobenzene-sulphone and 2 : 8 : 6 - acid; the monophthalamic acid of 2 : 5 - diaminobenzene-1-p-chlorobenzene-sulphone and 2 : 8 : 6 - acid; monoacetyl - 2 : 4 - diaminobenzene-1-p-toluenesulphone and 2-aminonaphthalene-6-sulphonic acid or 2 : 8 : 6-acid; monoacetyl - 1 : 4 - naphthylenediamine - 2 - p-toluenesulphone-6 (7)-sulphonic acid and ethyl-b -naphthylamine. A disazo dyestuff is prepared from the urea of 2 : 5 - diaminobenzene-1-p-toluenesulphone and 2 : 8 : 6-acid. The dyestuffs dye wool from an acid bath in orange-red to reddish-violet shades fast to washing and light.
