Abstract: The invention relates to a method for producing the tautomeric form (I) of 2,4,6-trianilino-p-(carbo-2'-ethylhexyl-1'-oxy)-1,3,5-triazine by the crystallisation of a tautomer mixture in the presence of one or more solvents selected from the group consisting of aliphatic alcohols having 2 8 C-atoms made of aliphatic alcohols, aliphatic carboxylic acid alkyl esters having a total of between 3 - 10 C-atoms, aromatic carboxylic acid alkyl esters having a total of between 8 - 12 C-atoms, aliphatic carboxylic acid esters having a total of between 3 9 C atoms, carboxylic acid nitriles having a total of between 2 - 8 C-atoms, dialkylketones having a total of between 3 - 6 C-atoms and aliphatic sulphones having a total of between 3 - 6 C-atoms. The solvent or solvent mixture can additionally contain up to 30 wt. % of a hydrocarbon. (I) acts as a light protecting agent in cosmetic preparations.

Abstract: The invention relates to a method for producing arylcarboxylic acid chlorides (I) substituted at least once by aryl (C1-C20) and/or halogen consisting, at a first stage thereof, in reacting an aromatic compound (II) substituted at least once by alkyl (C1-C20) and/or halogen with CCl4 in the presence of a Friedel-craft catalyst in such a way that corresponding trichlormethylated aromatic compounds (III) at least once substituted by aryl (C1-C20) and/or halogen are obtainable. At a second stage, the trichlormethylated aromatic compound (III) is treated with water or a proton acid in the presence of a catalyst, whereby making it possible to obtain an arylcarboxylic acid chloride (I). In the preferred embodiment, said trichlormethylated aromatic compound (III) is not isolated in the form of an intermediate product and, at the second stage used dissolved in the solvent of the first stage.
