Abstract: Disclosed is a method for separating acids from chemical reaction mixtures by means of an auxiliary base. Said auxiliary base b) forms a salt with the acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during separation, and c) the salt of the auxiliary base and the valuable product or the solution of the valuable product form two immiscible fluid phases in a suitable solvent.

Abstract: A process for preparing mono- or poly-C1-C20-alkyl- and/or -halogen-substituted arylcarbonyl chlorides (I), by, in a first stage, reacting a mono- or poly-C1-C20-alkyl- and/or -halogen-substituted aromatic (II) with CCl4 in the presence of a Friedel-Crafts catalyst to give the corresponding mono- or poly-C1-C20-alkyl- and/or -halogen-substituted trichloromethylated aromatic (III), and, in a second stage, treating the trichloromethylated aromatic (III) with water or a protic acid in the presence of a catalyst to obtain the arylcarbonyl chloride (I). In a particularly preferred embodiment, the trichloromethylated aromatic (III) is not isolated as an intermediate and is used in the second stage dissolved in the solvent of the first stage.
