Abstract: The process according to the invention comprises reacting the residues at temperatures of above 2000 DEG C and pressures of 1 to 100 bar with a gas mixture promoting combustion in a combustion chamber equipped with cooling devices. The gaseous reaction products which, upon leaving the combustion chamber, have temperatures of 200 to 800 DEG C are first cooled in a first cooling zone a) to temperatures in the range from 80 DEG C to 10 DEG C. The gaseous top products are treated in a process step b) in a suitable device with concentrated hydrochloric acid in the form of droplets having an average diameter of less than 500 mu .

Abstract: Solutions of N-vinylpyrrolidone polymers can be prepared with particular advantage by polymerization of N-vinylpyrrolidone in an aqueous medium by adding the polymerization catalyst in portions or continuously to the monomer solution in the form of a finely divided suspension in an aqueous solution of N-vinylpyrrolidone polymer.

Abstract: 1396755 Purifying waste water BADISCHE ANILIN- & SODA-FABRIK AG 6 Oct 1972 [7 Oct 1971] 46193/72 Heading C1C In a process for purifying waste water, containing suspended matter and resulting from the manufacture of a styrene bead polymer in the presence of a vinyl pyrrolidone polymer or vinyl alcohol polymer used as suspension stabilizers, the suspended matter is flocculated by heating the waste water in the presence of from 0À02 to 5% by weight of sodium, potassium or ammonium persulphate. The waste water may be heated to 110-180‹ C. in the presence of the persulphate. Activated charcoal, silica or bentonite may be added to the waste water before, during or after heating. The flocculate may be removed by a suction belt strainer or by means of a decanter.
