Title: A process for the manufacture of refined light hydrocarbon oils
IPC: C10G17/09
Filed: 1931-12-16
Abstract: Light hydrocarbons, especially those obtained by cracking, are refined by treating the vapour or liquid at about 130-260 DEG  C. with phosphorus pentoxide at normal, reduced, or increased pressure. An inert substance, e.g. sand, and/or a supplementary refining agent sweetening and stabilizing the hydrocarbon, are preferably used with the pentoxide.  A purification by weak acid, such as the solution of orthophosphoric acid obtained by leaching the residues from previous pentoxide treatments, followed by drying, is preferably given first; a wash with alkali is preferably given after.  Supplementary agents specified are oxidized mineral oils or bitumens, e.g. asphalt, coal tar pitch, wood tar pitch, and hardwood pitch, aldehydes, ketones, e.g. benzophenone, salts of organic acids, e.g. copper acetate, oleate, and naphthenate, and metallic halides e.g. cupric chloride, ferric chloride, and antimony trichloride.  In examples: (1) A mixture of 24 gm. of pentoxide and 6 gm. of asphalt with 1200 gm. of light mineral oil is distilled during 5 hours with constant stirring; the distillate is washed with soda.  (2) Gasolene vapours are passed through a mixture of pentoxide, copper naphthenate and wood tar pitch at 150-225 DEG  C.  (3) Pressure distillate is treated in an autoclave with 10 per cent of pentoxide, 17 per cent of copper naphthenate, and 30 per cent of sand, for 3 hours at 200 DEG  C.

Title: Improvements in or relating to methods of producing stable copper hydroxide
IPC: C01G3/02
Filed: 1937-12-22
Abstract: 510,082. Recovering copper compounds. NEW PROCESS RAYON, Inc. Dec. 22,1937, No..35484. Convention date, Jan. 26. [Class 1 (iii)] Copper is recovered from the waste acid liquor derived from the treatment of coagulated fibre of the cuprammonium process of producing rayon yarn by alkaline treatment of the liquor without substantial heating in the presence of seed crystals of basic green copper sulphate, whereby the green basic sulphate is precipitated, from which by further treatment with alkali a stable form of copper hydroxide may be obtained. In a modification, the liquor is treated without seeding to produce the blue basic sulphate which is boiled to obtain the green basic sulphate. Before precipitation of the sulphate, iron may first be removed by precipitating preferably as ferric phosphate, and when precipitating the green basic sulphate sufficient alkali, such as caustic soda, is first added to precipitate 50-75 per cent. of the copper, and precipitation then completed by adding further alkali. Seed crystals required initially may be prepared by adding alkali to the iron-free solution in stages precipitating only a small amount of copper at each addition. As the presence of an ammonium salt increases the density and grain size of the basic sulphate, ammonia may be used for precipitation when the waste liquor contains no ammonium compounds. Specification 503,193 is referred to.
