    Abstract: A compound of the formula: where R is hydrogen, C1-C4-alkyl, phenyl, chlorophenyl, methylphenyl, methoxyphenyl or nitrophenyl; R1 is allyl, C1-C8-alkyl, C1-C8-alkyl substituted by C1-C8-alkoxy, phenoxy, phenyl or C1-C8-alkanoyloxy, cyclopentyl, cyclohexyl, methylcyclohexyl, norbornyl, phenyl or phenyl substituted by chlorine, methyl or alkoxy; R2 is C1-C10-alkanoyl, C1-C10-alkanoyl substituted by alkoxy or phenoxy, cyclohexanoyl, benzoyl, benzoyl substituted by chlorine, methyl or methoxy, C1-C8-alkoxycarbonyl, aminocarbonyl, phenylaminocarbonyl, CH3NHCO, C2H5NHCO, C3H7NHCO, C4H9NHCO, (CH3)2NCO, CH3SO2, C6H5SO2 or p-CH3-C6H4-SO2; or R1 and R2, together with the nitrogen atom, form a ring system, and K is a radical of a coupling component. The isothiazolylylazo compound of the invention is useful for the dyeing of the polyesters, nylon, and cellulose esters.

    Abstract: The process is of sulphonating aryl compounds obtainable by pyrolysis of a naphthenic residual oil and fractional distillation of the pyrolysis products of the fraction produced at from 100 to 120 DEG C under atmospheric pressure, sulphonating this aromatic fraction using oleum at temperatures of from 120 to 160 DEG C in an amount of from 0.7 to 1.2 parts by weight of oleum, based on oleum having an SO3 content of 24 % by weight, per part by weight of the aromatic fraction, and subsequently condensing the arylsulphonic acids with formaldehyde in a known manner. The condensation products are used as dispersants, in particular in the preparation of dye formulations.
