Abstract: An oxidizable substance and/or a reducible substance is removed from a liquid, such as a liquid industrial waste, by treating the liquid with a composite comprising a fluorine-containing organic cation exchanger and a metal oxide or hydroxide, supported on the cation exchanger. The metal of the metal oxide or hydroxide is selected from manganese and elements of group 1B and group 8 of the periodic table. This treatment is carried out, if required, in the presence of an oxidizing agent, or by using the composite which has previously been treated with an oxidizing agent.

Abstract: 2089358 9302101 PCTABS00019 A method for crystallizing .alpha. -L-aspartyl-L-phenylalanine methyl ester (APM) by cooling. In this method, crystals of APM are subjected to crushing, and the crushed APM crystals are used as seed crystals for growing APM crystals. By the use of crushed seed crystals, the generation of fine secondary APM crystals can be suppressed, and the width to length ratio of resulting APM crystals becomes larger. As a whole, big APM crystals having improved filtering and drying properties can be obtained. Such crystals can be advantageous with regard to production, quality and handling. The precipitation of APM crystals proceeds quite efficiently with only a small quantity of crushed seed crystals. This invention also relates to crystallization of APM using in situ prepared crushed seed crystals.

Abstract: Disclosed is a granular calcium hypochlorite composition having a calcium hypochlorite content of at least 55 wt.% and composed of particles having an ellipsoidal shape in section, wherein at least 50 wt.% of the ellipsoidal particles have a short diameter of 0.3 - 5 mm, a long diameter of 0.5 - 20 mm, and a long diameter/short diameter ratio larger than 1.5 but not larger than 5. This composition is prepared by a process wherein a wet calcium hypochlorite composition comprising at least 40 wt.% of calcium hypochlorite and 25 - 45 wt.% of water is extruded through a die having an orifice diameter of 0.3 - 5 mm; the extrudate is cut to a length of 0.5 - 20 mm so that the length/orifice diameter ratio is larger than 1.5 but not larger than 5 to form columnar shaped particles; the columnar shaped particles are subjected to rolling granulation; and the resulting granules are dried until the water content is reduced to 4 - 22 wt.%.

Abstract: A granular calcium hypochlorite composition comprising a particle of calcium hypochlorite dihydrate and/or calcium hypochlorite anhydride, the surface of which has been covered with a double decomposition product of calcium hypochlorite and an alkali metal hydroxide. This composition is prepared by adhering an aqueous alkali metal hydroxide solution to the particle of calcium hypochlorite dihydride or calcium hypochlorite anhydride, and the drying the particle.

Abstract: To provide a process for recovering high quality hydrogen chloride rationally with good economical efficiency, particularly hydrogen chloride with an elevated quality level to be provided as the feedstock for the oxychlorination reaction in producing dichloroethane and a vinyl chloride monomer from a hydrogen chloride gas to be generated by the combustion of chlorine based waste. To use a process for recovering hydrogen chloride from chlorine based waste comprises adding water and a reducing agent to an acid gas obtained by the combustion of chlorine based waste to effect reaction to obtain a crude hydrogen chloride aqueous solution having an oxidation-reduction potential of not higher than 900 mV and then, distilling the crude hydrogen chloride aqueous solution to obtain a purified hydrogen chloride gas.
