摘要： A continuous process for purifying an off-gas which contains CO.sub.2 and HCl and COCl.sub.2. The process comprises passing the off-gas through a separator filled with N,N-dialkylformamide and HCl. This causes a reaction between the COCl.sub.2 and the N,N-dialkylformamide to give the Vilsmeier complex (adduct of COCl.sub.2 and dialkylformamide) and CO.sub.2. The CO.sub.2 leaving the separator contains small amounts of HCl.

摘要： Carbonyl halides of the general formula I ##STR1## where R is an organic radical of more than 7 carbon atoms and X is chlorine or bromine, are prepared by reacting carboxylic acids of the general formula II ##STR2## where R has the abovementioned meaning, with phosphorus chlorides or bromides by treating these reaction mixtures with carboxamide/hydrochloride or hydrobromide mixtures which are not homogeneously miscible with the carbonyl halides I and then separating off the carboxamide hydrochloride or hydrobromide phase.
