Abstract: Stabilised aqueous C14- to C22-alkyldiketene emulsions containing, as essential components, (a) 10 to 60 % by weight of at least one C14- to C22-alkyldiketene, (b) 1 to 10 % by weight of at least one protective colloid and (c) 0.1 to 20 % by weight of at least one ester of the formula in which R , R are C14- to C22-alkyl, in which case R and R must differ in the alkyl group by at least 4 C atoms, and/or denote identical or different C14- to C22-alkenyl groups, an ester of the formula R -O-CO-O-R (II), in which R and R are alkyl or alkenyl radicals having 2 to 22 C atoms or a urethane of the formula in which R , R and R are identical or different alkyl or alkenyl radicals having 2 to 22 C atoms, and the use of the compounds of the formula I to III as stabiliser for the preparation of alkyldiketene emulsions containing at least 10, preferably 16 to 40 % by weight of alkyldiketene in emulsified form.

Abstract: A continuous process for purifying an exhaust gas composed of CO2 + HCl + COCl2, in which by means of a separator filled with N,N-dialkylformamide ô HCl - COCL2 is reacted with N,N-dialkylformamide to give the Vilsmeier complex and CO2, and - CO2/HCl and HCl are removed separately from the separator.

Abstract: Process for the preparation of carboxylic acid chlorides of the general formula I in which R represents C1- to C30-alkyl, C2- to C30-alkenyl and C2- to C30-alkynyl, from essentially equimolar amounts of a carboxylic acid of the general formula II in which R has the abovementioned meanings, and phosgene COCl2 (III), in the presence of a catalyst adduct of phosgene and N,N-disubstituted formamide or their hydrochlorides of the general formula IV in which R and R independently of one another denote C1- to C3-alkyl or R and R together denote a C4- or C5-alkylene chain which can optionally be interrupted by an oxygen atom or a nitrogen atom having a C1- to C3-alkyl group or CHO, and n is 0, 1 or 2, the reaction being carried out with a static phase of the catalyst adduct.
