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.

Abstract: Hydroxypivalic acid is obtained from aqueous solutions by removal of the water by azeotropic distillation and subsequent crystallization from a solvent mixture which is composed of a polar and a non-polar component. The distillation is carried out under reduced pressure and at a maximum bottom temperature of 90.degree. C., until a residual water content of at least 0.1% of the total weight of the resulting solution is achieved.

Abstract: A process for separating off poorly soluble by-products from reaction mixtures which are produced in the oxidation of p-cresol with oxygen or an oxygen-containing gas in methanol as solvent in the presence of alkali metal hydroxide and in the presence of metal compounds as catalyst, is characterized in that, after the oxidation, excess alkali is neutralized to the extent that a salt precipitate forms and this salt precipitate is separated off together with the poorly soluble by-products.
