Title: Improvements in or relating to chlorinated polymers
IPC: C08F8/20
Filed: 1947-05-16
Abstract: Solid or semi-solid polymers, copolymers or telomers of ethylene are chlorinated by the action of liquid chlorine preferably in the presence of actinic light.  The polymers, copolymers or telomers may be those referred to in Specifications 471,590, 497,643, 578,584, 578,992, 581,899, 583,181, 584,795 and 585,396.  Low and elevated temperatures may be used with appropriate pressures.  At a given temperature liquid chlorine dissolves a chlorinated polymer of specific chlorine content, the chlorine content in the dissolved chlorinated polymer being lower with increase in temperature, so that a particular chlorinated polymer can be obtained by operating at the required temperature and withdrawing the solution of the chlorinated polymer in the liquid chlorine.  The process may be continuous, particularly when carried out in a long tube with several discharge openings spaced along its length.  A solvent for both chlorine and the chlorinated polymer may be present, those specified being carbon tetrachloride, dichlorodifluoroethane and tetrachloroethylene. The products may be used in making films, filaments, coatings, gaskets, washers, adhesives and for water-proofing.  Fillers, pigments, dyes and plasticizers may be added.  Specifications 481,515 and 576,119 also are referred to.

Title: Improvements in the Manufacture of Anhydrous Magnesium Chloride alone or conjointly with other Metal Chlorides.
Inventor: ASHCROFT EDGAR ARTHUR
IPC: C01F11/28
Filed: 1916-09-19
Abstract: 108,920. Ashcroft, E. A. Sept. 19, 1916. Magnesium, manganese, chromium. iron, and tungsten chlorides.-The reaction of chlorine upon magnesia suspended in a fused medium as described in Specification 108,755 is facilitated by having present a small quantity of a catalyst capable of carrying chlorine. Suitable catalysts are iron, ferro-manganese, ferro-tungsten, ferrochromium, iron oxide, iron sulphide or pyrites, manganese sulphide, and chromium salts. At the end of the reaction, the catalytic metal may be removed by precipitation; for instance, ferrous chloride may be removed by precipitation with a little magnesia, or by reduction with metallic lead, in which case a lead-iron alloy is formed, which also contains any silver, gold, or copper that may be present in the pyrites or added sulphides, and is treated for these metals ; or the catalyst mav be removed as a volatile chloride (ferric chloride &c.). Any carbon remaining in the melt may be removed by a current of air or oxygen, and the temperature of the melt may be raised at any stage of the process by adding carbon and removing it in this manner. Alkali chlorides may be added to the melt to increase the fluidity or lower the melting-point, before electrolysis, the greatest effect being obtained when sodium, potassium, and magnesium chlorides are present in molecular proportions, this melt being very suitable for the electrolytic extraction of magnesium. Carnallite may also be added to the melt. When a sulphide such as lead or zinc sulphide is used with the magnesia, such substances as lead or zinc concentrates, which usually contain enough iron or manganese to act as catalyst, may be used instead of blende or galena, and no separate addition of catalyst is then necessary. Lead or zinc fumes or residues may be added to the melts, and the metals may be converted into chlorides. Instead of magnesia, magnesium oxychloride or sulphate may be used, any water of hydration causing the evolution of hydrochloric acid. Specifications 7444/10 and 24170/11 also are referred to.
