Abstract: Process for the purification of carbonyl chlorides which have been prepared by reacting carboxylic acids with phosgene or thionyl chloride in the presence of a catalyst adduct, in which the carbonyl chlorides are treated with a hydrohalide of carboxamides of the formula (I)in which R is hydrogen or C1- to C3-alkyl; R and R independently of one another are C1- to C4-alkyl, or R and R together are a C4- or C5-alkylene chain, and the carbonyl chloride purified in this way is isolated by separation off from the carboxamide hydrohalide phase.

Abstract: The invention relates to a method for producing chlorocarboxylic acid chlorides of formula (I), wherein R and R , independently from one another, mean a hydrogen atom, an organic radical containing carbon, a halogen, a nitro or cyano group and Y means an alkylene chain having 1 to 10 carbon atoms in the chain which is unsubstituted or is substituted by organic radicals that contain carbon, by halogen, nitro and/or cyano groups, whereby the alkylene chain can be interrupted by an ether-, thioether-, tertiary amino- or keto group, whereby the organic radicals of Y and/or R and/or R can be connected to one another and thereby form a non-aromatic system, whereby said radicals contain carbon, by converting a lactone of formula (II), wherein R , R and Y have the aforementioned meanings, using a hydrogen chloride and phosgene in the presence of a catalyst. Hydrogen chloride is added before and/or while phosgene is added. The hydrogen chloride is only introduced at a temperature of at least 60 DEG C. A pyridine compound is used as the catalyst.

Abstract: The invention relates to a method for producing o-choromethyl benzenecarbonyl chlorides of formula (I), wherein R -R can be the same or different and stand for hydrogen, C1-C4-alkyl, halogen or trifluoromnethyl, by converting benzocondensed lactones of formula (II), wherein R -R have the aforementioned meaning, with gaseous or liquid phosgene and the dimers or trimers thereof. The inventive method is characterized in that the conversion is carried out in the presence of catalytical amounts of a Lewis acid and catalytical amounts of a phosgenation catalyst
