    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: Prodn. of carboxylic acid halides of formula RCOX (I), where R= an organic gp. contg. more than 7 C atoms and X=Cl or Br, is effected by (a) reacting RCOOH with a P halide, (b) treating the reaction mixt. with a carboxamide hydrochloride or hydrobromide (II)which is immiscible with (I), and (c) sepg. the (I)-contg. phase. Pref. step (a) is effected by reacting a 9-29C fatty acid with PCl3. Step (b) is effected by adding an amide (esp. DMF) to the reaction mixt. and then introducing HCl.
