    Abstract: A reactor for testing catalyst systems which has a plurality of catalyst tubes ( 2 ) which are arranged parallel to one another in the interior space of the reactor and whose ends are welded into tube plates and also has caps ( 3 ) at each end of the reactor which each bound a cap space ( 4 ), with a fluid reaction medium ( 5 ) being fed via one cap space ( 4 ) into the catalyst tubes ( 2 ), flowing through the catalyst tubes ( 2 ) and being discharged via the other cap space ( 4 ), and is also provided with a heat exchange medium circuit in which the heat exchange medium ( 6 ) is fed in at one end of the reactor, flows through the intermediate space between the catalyst tubes ( 2 ) and flows out at the other end of the reactor, wherein the catalyst tubes ( 2 ) are arranged in two or more catalyst tube regions ( 7 ) which are thermally separate from one another, is proposed.

    Abstract: Vinyl formate copolymers, preparation thereof, and use thereof in detergents and cleaners Copolymers containing (a) from 5 to 90 mol% of vinyl formate units, (b) from 10 to 95 mol% of units of monoethylenically unsaturated carboxylic acids, (c) from 0 to 70 mol% of units of monoethylenically unsaturated dicarboxylic acids, and (d) from 0 to 30 mol% of units of other monoethylenically unsaturated monomers in copolymerized form and having K values of at least 8 (determined by the method of H. Fikentscher in 1% strength by weight aqueous solution on the sodium salt of the copolymers at pH 7 and 25 C), processes for their preparation by copolymerizing monomer mixtures of (a) from 5 to 90 mol% of vinyl formate, (b) from 10 to 95 mol% of monoethylenically unsaturated carboxylic acids, (c) from 0 to 70 mol% of monoethylenically unsaturated dicarboxylic acids, and (d) from 0 to 30 mol% of other monoethylenically unsaturated monomers in an aqueous medium or in an organic solvent in the presence of free-radical polymerization initiators and use of the vinyl formate copolymers and of the vinyl alcohol copolymers obtainable therefrom by hydrolysis and/or oxidation as detergent and cleaner additives.
