    Abstract: 2-Chloro-6-nitrophenyl alkyl sulphides of the formula ##STR1## in which the substituents are as defined in the description, can be prepared by reacting 2,3-dichloro-nitrobenzenes of the formula ##STR2## with mercaptans of the formulaHS-R.sup.1 (III)in the presence of 1-1.2 equivalents of a base per mole of mercaptan and in the presence of a phase transfer catalyst, at a temperature of 0.degree.-100.degree. C., in an aqueous or aqueous-organic medium. The majority of the 2-chloro- 6-nitrophenyl alkyl sulphides obtainable in this way are novel.

    Abstract: Alkylated aromatic amines can be isolated from crude catalyst-containing mixtures of these with olefins by a procedure in which in general equivalent amounts of an inorganic base and water are added to the alkylation mixture, the catalyst is hydrolysed, the water present in the reaction mixture after the hydrolysis is removed by distillation and the solid catalyst residue is separated off. The catalyst-free alkylation mixture which remains is then fed to customary further working up.
