Abstract: The present invention relates to a starch which is modified with at least one cationic polymer and a method for its production, which is characterized in that dry, pourable starch is laid out and the cationic polymer is applied over it without causing the starch particles to stick. The invention further relates to the use of said polymer-modified starches.

Abstract: Process for the continuous preparation of carboxylic acid chlorides (I) of the general formula R-COCl, in which R is a C-organic radical having 1 to 30 C atoms, by reaction of a carboxylic acid R-COOH (II) with a reaction product (III) of phosgene (IV) and an N,N-disubstituted formamide (V), in which II and III are passed in counter-current from below into a zone (2) packed with III of a reactor (1), the reaction mixture is allowed to rise in predominantly laminar flow, a phase separation into an upper phase I and a lower phase III' of predominantly III and resultant formamide being obtained and I being withdrawn from the upper phase and parts of the lower phase III' according to its formation.
