Title: Improvements in or relating to the production of vinyl chloride
Inventor: CAPP CLIFFORD WILLIAM
IPC: B01J27/06
Filed: 1965-01-19
Abstract: Vinyl chloride is prepared by reacting ethylene, hydrogen chloride and/or chlorine and molecular oxygen in the vapour phase at 350-600 DEG  C. in the presence of a supported catalyst containing Cu which, under the reaction conditions, is in the form of the oxide, chloride or oxychloride, an alkali and/or alkaline earth metal which, under the reaction conditions is present as a chloride, or oxychloride, if such exists, and one or more of iron, yttrium, a rare earth metal, circonium, uranium, thorium or titanium, which are present as the oxide, chloride or oxychloride. The catalyst may be supported on a carrier, e.g. alumina, silica or pumice (see Division B1E). The ethylene feed may be admixed with ethane which can also form vinyl chloride under the reaction conditions.  An example describes the use of a Cu/K/Ce catalyst; some vinylidene dichloride, 1,2 - dichloroethane and trichloroethylene occur in the vinyl chloride product.  Reference has been directed by the Comptroller to the Specification 969,937.ALSO:Catalysts for the oxychlorination of ethylene comprise an oxide, chloride or oxychloride of copper, a chloride of an alkali and/or alkaline earth metal, an oxide, chloride or oxychloride of one or more of the rare earth metals, iron, yltrium, zirconium, uranium, - thorium or titanium and a suitable support material, e.g., alumina, silica or pumice.  The catalyst preferably contains 0.5-10% Cu, 0.2-10% alkali or alkaline earth metal and 0.2-10% rare earth, Fe, Y, Zr, U, Th or Ti, based on the weight of the catalyst and support.  The catalyst may be prepared by impregnating the carrier with solutions of the metal salts.  The metal salts may be those which decompose or react under the oxychlorination conditions to give the oxides chlorides or oxychlorides, e.g. nitrates, hydroxides, formates, oxalates, acetates, aluminates of alkali or alkaline earth metals or certain organic-metallic compounds, e.g. butyl titanate.  The preferred support is activated alumina which has been pre-heated to 900 - 1400 DEG C.  An Example describes a catalyst consisting of cupric chloride/potassium chloride/cerium chloride/alumina.  Reference has been directed by the Comptroller to Specification 969,937.

Title: Improvements relating to the removal of free chlorine from chlorine-containing materials and to the production of chlorine-removing material therefor
IPC: C01B7/01
Filed: 1932-01-26
Abstract: Free chlorine is removed from materials containing it by subjecting the materials, preferably in the presence of water, to the action of carbon which has been activated with water vapour at a temperature of 800-1000 DEG  C.  The chlorine is converted into hydrochloric acid. The carbon should preferably be moulded to a suitable grain size before activation or may be reduced from irregularly-shaped charcoal into uniformly rounded pieces by mutual attrition in a grinding drum or the like.  Water containing free chlorine may be rendered chlorine free by passage through a filter comprising a layer of the said carbon.  Chlorine dissolved in organic liquids or gaseous chlorine contained in a mixture of gases can be removed by sending such liquids or mixtures of gases through filters comprising the carbon together with liquid water. These gases may also be passed up a series of scrubbers filled with the carbon down which water percolates.  Solid substances may be similarly purified when in suspension in water.ALSO:Free chlorine is removed from liquids containing it by subjecting the liquids, preferably in the presence of water, to the action of carbon which has been activated with water vapour at a temperature of 800-1000 DEG  C.
