Title: Improvements in or relating to the production of antimony tri-flouride
IPC: C01G30/00
Filed: 1931-07-13
Abstract: Antimony trifluoride is prepared by treating another antimony trihalide such as the chloride with liquid, gaseous or aqueous hydrofluoric acid in the presence of a solvent for the trichloride such as water or hydrochlorine acid, ethyl alcohol, carbon tetrachloride, nitrobenzol, chloroform, or dichlorbenzene. In examples, a mixture of nitrobenzene and antimony chloride is treated at 125-150 DEG  C. with gaseous hydrofluoric acid, the insoluble fluoride formed being separated and washed with carbon tetrachloride; a mixture of carbon tetrachloride and antimony chloride is treated with gaseous hydrofluoric acid at 60-75 DEG  C., the insoluble fluoride being separated and washed as before; and a mixture of antimony chloride with a small amount of water is treated with gaseous hydrofluoric acid at 100 DEG  C. and the insoluble fluoride separated.  Reaction may be effected continuously and if desired under pressure, and excess hydrofluoric acid may be used.  When alcohols are used as solvents, their halogen derivatives may be obtained as bye-products.  The Specification as open to inspection under Sect. 91 comprises also the following subject-matter:--The preparation of the trifluoride in the absence of a solvent, including examples wherein anhydrous antimony trichloride is treated with liquid hydrogen fluoride at 0-8 DEG  C., excess acid is removed by evaporation at 40-50 DEG  C., and residual chloride removed by carbon tetrachloride; and melted antimony chloride crystals are treated at 75-85 DEG  C. with gaseous hydrogen fluoride.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to derivatives of-a-,-a-unsaturated perfluorocarbon acids
IPC: C07C69/653
Filed: 1951-05-10
Abstract: The invention comprises compounds <FORM:0737227/IV (b)/1> where X is -OR, -NH2, -NR2 or -SR, Rf and R1f being perfluoroalkyl radicles or F and R being an alkyl radicle or compounds RfCF = CR1fCN produced by reacting ROH with RfCF2CR1f = CF2 under alkaline conditions to yield RfCF2CR1fHCF2OR which on acid hydrolysis at below about room temperatures yields RfCF2CR1fHCOOR which with ammonia yields the corresponding amide which is dehydrated and dehydrofluorinated to RfCF = CR1fCN.  Specified perfluorocarbon groups are CF3 and C2F5. The ester RfCF2CR1fHCOOR may be dehydrofluorinated to RfCF = CR1fCOOR and the amide RfCF2C1RfHCONH2 by direct dehydrofluorination yields the corresponding unsaturated perfluoroamide with substantial quantities of RfCF = CR1fCN.  The olefine RfCF2CR1f = CF2 may be reacted with an amine HNR2 to yield an amine RfCF2CR1fHCF2NR2 which on hydrolysis yields the corresponding amide which can be dehydrofluorinated to the unsaturated amide RfCF = CR1fCONH2.  The above olefines may be reacted with mercaptans RSH to yield thioethers RfCF2CR1fHCF2SR which may be hydrolysed to the thio-esters and dehydrofluorinated to the corresponding unsaturated esters.  In illustrations CF3CF = CF2 is bubbled at 30 DEG  C. through methanol containing potassium hydroxide to yield CF3CFHCF2OCH3 which is hydrolysed with sulphuric acid at below 10 DEG  C. to yield CF3CFHCO2CH3, the ester is converted to the amide by treatment in ether at 0 DEG  C. with anhydrous ammonia and the amide is dehydrated with an excess of either P2O5 or PCl5 at 50-300 DEG  C. to yield CF3CFHCN which is dehydrofluorinated by passage over chromia or potassium fluoride or chloride at 500-800 DEG  C., preferably 600 DEG C., to yield CF2 = CFCN.  The ester CF3CFHCOOCH3 passed over potassium chloride at 600-800 DEG  C. yields an unsaturated ester which on bromination forms CF2BrCFBrCOOCH3.  In a similar way starting from CF3CF2CF = CF2 the following compounds may be obtained: CF3CF2-CFHCH2OCH3, CF3CF2CFHCOOCH, CF2-CF2CFHCONH2, CF3CH2CFHCN and CF3 = CFCN, the latter being hydrolysed to the corresponding carboxylic acid.  The unsaturated products may be used in the production of polymers or copolymers. Specification 737,164 is referred to.

Abstract: 148,794. Detroit Pressed Steel Co., (Assignees of Putnam, A. L.). Aug, 26, 1915, [Convention date]. Wheels. - In the formation of sheet-metal wheels in which the gauge of the metal is different at different parts of the wheel, blanks are cut from sheet metal of a gauge equal to the maximum thickness of the wheel, the central portion is cupped to initiate the hub formation, and the surrounding portions are thinned as required and pressed to the desired form. In the formation of wheels in which the metal at the hub is of greatest, that of the spokes of least, and that of the rim of intermediate thickness, a circular blank A of the maximum thickness is first cupped as at B and revolubly mounted on a guide E. The blank is subjected to the action of two pairs of conical rollers C, C<1>, D, D<1> which bear on opposite faces and on diametrically opposite sides of the blank to reduce the metal to the required thickness in the spoke and rim areas. The blanks are then formed into wheels preferably by providing complementary members electrically welded or otherwise secured to each other in the central plane of the wheel. Each member has a hub section B, hollow spoke sections F with the metal intermediate the spokes cut away and a rim section G.

Title: Improvements in and relating to the production of cellulose derivatives
IPC: C08B11/04
Filed: 1939-07-18
Abstract: 531,698. Cellulose ethers. REICHEL, F. H. July 18, 1939, No. 20906. [Class 2 (ii)] Cellulose ethers which are soluble in aqueous media are obtained by subjecting cellulose or alkali cellulose to the action of an etherifying agent in the presence of an aqueous alkali solution and a quantity of an inert watersoluble salt in anhydrous state, and allowing the salt, by its hydration, to bind water, thereby increasing the effective concentration of the alkali solution. The water-soluble salt may be sodium sulphate, sulphide, carbonate, tetraborate, acetate, or citrate, or potassium carbonate, citrate, lactate, or borate, or lithium acetate, borate, or citrate, or calcium, barium, or strontium chloride. The salt may be used in an amount of 50-200 per cent. of the dry cellulose. The cellulose starting material may be cotton, flax, hemp, jute, straw, wood, sulphite cellulose, cotton linters, regenerated cellulose, oxy-cellulose, or hydro-cellulose. If cellulose ether xanthates are desired, the starting material may be cellulose xanthate. The cellulose may be first converted into alkali cellulose and pressed. The alkali used may be caustic soda or potash or a quaternary ammonium hydroxide. The etherifying agent may be methyl or ethyl chloride, bromide, or sulphate, sodium ethyl sulphate, ethylene chlorhydrin, propylene chlorhydrin, epichlorhydrin, ethylene oxide, a glycide, chlor-acetic acid, chlorpropionic acid, or other halogen fatty acid or a salt or ester thereof. The salt may be added to the cellulose after mercerizing with alkali, or during shredding or ageing. The salt may also be added to the liquors employed for purifying and washing the product. In an example, cotton linters are soaked in caustic soda solution, pressed, shredded, and aged. Anhydrous sodium sulphate is added to the alkali cellulose and the mixture is stirred for 3 days. Ethylene oxide is then added to the reaction vessel and the etherification is allowed to take place at a low temperature. The product is acidified and then washed with water. It is soluble in 6-10 per cent. caustic soda solution.
