Title: Continuous process for the manufacture of calcium hypochlorite
Inventor: SAKOWSKI WALTER J
IPC: C01B11/06
Filed: 1983-11-10
Granted: 1985-06-11
Abstract: CONTINUOUS PROCESS FOR THE MANUFACTURE OF CALCIUM HYPOCHLORITE              ABSTRACT OF THE DISCLOSURE            A continuous process for the production of calcium hypochlorite comprises admixing a slurry of lime containing insoluble impurities with a saturated calcium hypochlorite solution in a crystallizing zone.  An impure slurry of coarse dibasic calcium hypochlorite crystals, small crystals of dibasic calcium hypochlorite, and fine insolubles comprised of unreacted lime particles and fine insolubles in a mother liquor is formed.  The slurry is fed to the intermediate section of a separation zone.  An aqueous sodium chloride elutriant is fed to the lower section of the separation zone to contact the slurry and to separate a slurry of fine insolubles and small crystals of dibasic calcium hypochlorite in elutriant from the dibasic calcium hypochlorite crystals.  Small crystals of dibasic calcium hypochlorite are separated from the fine insolubles in the intermediate section of the separation zone.  These small crystals can be recycled to the crystallizing zone or destroyed by chlorination.  The slurry of fine insolubles is conveyed in the elutriant to the upper section of the separation zone. A slurry of purified coarse dibasic calcium hypochlorite crystals in elutriant is removed from the lower section of the separation zone, the rate of removal of the purified coarse crystals of dibasic calcium hypochlorite being controlled to maintain a rising velocity in the lower section of the separation zone of from about 0.5 to about 7,centimeters per minute.  Purified coarse dibasic calcium hypochlorite crystals are separated from a dibasic calcium hypochlorite mother liquor, and admixed with an alkali metal hypochlorite solution to produce a mixed alkali slurry.  The mixed alkali slurry is chlorinated to form a slurry of calcium hypochlorite dihydrate crystals in a saturated calcium hypochlorite solution.  The slurry of calcium hypochlorite dihydrate crystals is separated to provide a cake of calcium hypochlorite dihydrate crystals and a saturated calcium hypochlorite solution.  The cake of calcium hypochlorite dihydrate crystals is dried to produce granular calcium hypochlorite.  The saturated calcium hypochlorite solution is recycled to the crystallizing zone.

Abstract: ABSTRACT OF THE DISCLOSURE                              Pulverulent polymers based on water-soluble ethylenically unsaturated monomers are prepared by polymerizing monomers, which contain acidic groups and are dissolved in water or a water/isopropanol mixture, in a powder bed in the presence of a conven-tional polymerization initiator while maintaining the powder state, conducting away the heat of polymerization by distilling off the solvent and circulating the reac-tion mixture, by a process in which from 40 to 95% of the acidic groups of the monomers are neutralized and the polymerization is carried out in the presence of from 3 to 10 mole%, based on the monomers, of a thiocarboxylic acid, of a metal salt or chelate, of an enol-ether or of Z-mercaptoethanol as a regulator.        The homopolymers and copolymers thus obtained are used as milling assistants and dispersants for pigments and as encrustation inhibitors and antiredeposition agents for detergents.

Abstract: ABSTRACT   The present invention relates to a method and an apparatus for production of cartridged propellant charges for barrel weapons with charge weights up to 1.4 kg/litre.  According to the invention, more granular or particle-shaped propellant powder is driven down or compacted than can be housed in free-running condition within the same volume by means of a piston or plunger in a single stage into a case, the inside of which is coated with a friction-reducing compound.  The piston or plunger can then be provided with an elastically deformable loading part of e.g. rubber, and/or with a conically tipped leading end.  According to one variant of the invention, the powder is pressed down into a bag of combustible fibre material which has been inserted in advance down into the case coated internally with a friction-reducing com-pound or which has itself been impregnated with a friction-reducing compound.          The invention also enables the powder to be compacted to advantage at a temperature that is higher than the room temperature.
