  • Process for the producing concentrated solution of sodium hydroxide and chlorine
    Patent number: 4395314
    Abstract: The process according to the present invention relates to the production of a concentrated solution of sodium hydroxide and chlorine which comprises electrochemical decomposition of a concentrated solution of sodium chloride with a concentration of from 4.3 to 5.3 mol/l at a temperature within the range of from 90.degree. to 108.degree. C. with the degree of decomposition of sodium chloride of 0.9 to 1.0 and the rate of flow of the solution of sodium chloride through a filtering diaphragm of from 3 to 5 ml/hr per 1 A of the electrolysis current, followed by removing the electrolysis products from the process.The process according to the present invention makes it possible to substantially simplify the known procedure of chlorine manufacture, since it ensures obtaining the final commercial product directly in the electrolysis, thus avoiding the stage of evaporation.

  • Process for preparing allyl chloride
    Patent number: 4244892
    Abstract: In accordance with the present invention, the process for preparing allyl chloride comprises chlorination of propylene with hydrogen chloride in an upward stream consisting of propylene, hydrogen chloride and a catalyst, i.e. manganese dioxide incorporated in a leaned manganese ore in an amount of 20 to 35% byu weight at a temperature within the range of from 300.degree. to 500.degree. C., concentration of the catalyst in the stream of 130-180 kg/m.sup.3, time of contact between propylene, hydrogen chloride and the catalyst in the stream of 0.2-0.7 sec and a volume ratio between propylene and hydrogen chloride in the stream of 1:3-5 respectively. Then the spent catalyst is separated from the reaction mixture resulting from chlorination, regenerated with oxygen at a temperature of from 500.degree. to 520.degree. C. and recycled to the chlorination process. The process according to the present invention makes it possible to achieve a yield of allyl chloride of up to 81.5 vol.

  • Solid electrode electrolyzer for electrolysis of aqueous solutions
    Patent number: 4136004
    Abstract: An electrolyzer for electrolysis of aqueous solutions of alkali metal chlorides, comprising a horizontal casing filled with an electrolyte and two end monopolar electrodes placed therein. The casing of the electrolyzer is a cylinder made from a corrosion-resistant nonconducting material, its bases being secured to the bases of the monopolar electrodes, thus forming a tight cylindrical chamber.
