Patent GB-860327-A (GB)
Title: Preparation of graft co-polymers
IPC: C08F283/12
Filed: 1959-02-26
Abstract: Graft polymers are made by (a) exposing an organo-siloxane polymer of the unit formula <FORM:0860327/IV (a)/1> wherein n is 1, 2 or 3 and each R is a monovalent hydrocarbon, halohydrocarbon, hydrocarbonoxy or hydroxy radical or a hydrogen atom, at least some of the R's being organic radicals, to ionizing radiation at a temperature at least as low as the second order transition temperature of the polymer and in the substantial absence of oxygen diffusion into the polymer, and thereafter (b) contacting the irradiated polymer with a grafting material, and (c) raising the temperature of the reactants above the second order transition temperature.  The siloxanes used may be polymers, copolymers or mixtures, may be resins (cured or uncured), liquids or eleastomers, and may contain conventional fillers and other additives provided that they are inert to the ionizing radiation. The grafting material can be the same as the trunk material but preferably is a different material, e.g. vinyl chloride, butadiene, acrylonitrile, acrylamide, styrene, vinylidene dichloride, vinylcarbazole, isoprene, ethylene, polypropylene, natural rubber, tetrafluoroethylene and chlorotrifluoroethylene, and can be used in the solid, liquid or vapour form.  The radiation may be b -, g  or X-rays, neutrons, accelerated electrons or heavy particles.  The grafting may be effected in the presence of chain transfer agents, e.g. mercaptans, CCl4 and HCBr3, which, if desired, may form part of the siloxane, e.g. as in haloalkyl radicals.  The whole siloxane or just the surface thereof can be subjected to grafting.  The process results in grafting as well as vulcanizing or cross-linking of the siloxanes.  In typical Examples, (1) a mixture of a dimethylsiloxane gum, fume silica and a hydroxy-terminated dimethylsiloxane, was compounded on a mill and formed into sheets which were immersed in liquid nitrogen and exposed to g -rays; the irradiated sheets were removed and immediately dropped into liquid methylmethacrylate, acrylonitrile, vinyl acetate, a 50% solution of acrylonitrile in dimethylformamide, and styrene, all at room temperature; the sheets while still immersed were heated on a steam bath; (2) a liquid dimethylsiloxane, contained in a test tube, was immersed in liquid nitrogen and exposed to g -rays; methyl methacrylate was then added to the still frozen siloxane (after removal of the liquid nitrogen) whereupon rapid and vigorous reaction took place; (6) an uncured methylphenylsiloxane copolymeric resin was cooled in dry ice and exposed to g -rays and then immersed in acrylonitrile at room temperature.  Uses.-For making new materials; surface treatment of shaped forms; modifying polymers and their properties; and vulcanizing elastomeric stocks.

Title: A new antibiotic karnatakin and a process for the production and isolation thereof
Inventor: PINTO PATRICK VINCENT CARMEL
Filed: 1957-02-28
Abstract: An antibiotic karnatakin is prepared by cultivating a karnatakin-producing strain of Streptomyces karnatakensis nov. spec. in a nutrient medium containing organic nitrogen, carbohydrates and minerals under aerobic and preferably submerged aerobic conditions. Oilcakes, fish meal, meat extract and wheat bran are suitable nitrogen sources.  Starch and molasses are suitable carbohydrate sources.  A typical aqueous medium contains coconut cake 1 to 5%, starch 1 to 4% and sodium chloride 0,25 to 1,0%.  The initial pH of the medium is 5,5 to 7,2, the temperature of cultivation 30 DEG C. and the duration of cultivation 15 to <PICT:0852472/IV(b)/1> <PICT:0852472/IV(b)/2> 20 days for surface culture, less for submerged cultivation.  The antibiotic is at first present in the cells and then in the broth. Adjustment of pH to 2,5 causes lysis of the cells and the antibiotic is then recovered from the filtrate by (a) adsorption on activated carbon at pH 2 to 10, followed by elution with acidic or alkaline organic solvents such as ethyl alcohol and acetone and removal of the solvent in vacuo at below 30 DEG C.; or (b) extraction by a waterimmiscible organic solvent such as chloroform or ethyl ether.  The antibiotic is a brownish yellow viscous liquid darkening on exposure to heat or on drying.  It is active against gram positive and gram negative bacteria including Mycobacteriaceae.  It is insoluble in water, benzene and ether but moderately soluble in chloroform, ethyl acetate and acetone, freely soluble in methanol and ethanol.  It has a Rf value of 0,5 when chromatographed on paper using a chloroform/ethyl acetate mixture (4:1) saturated with water.  Contains 55,3% carbon, 5,8% hydrogen and 7,5% nitrogen; its ultraviolet absorption spectrum in ethanol shows a maximum at 237 mm  (Fig. 2) and its infra-red absorption spectrum shows maxima at 1726, 1665, 1610 and 1279 cm-1.

Patent GB-491927-A (GB)
Title: Process for the production of aliphatic carboxylic acids
Filed: 1937-03-09
Abstract: Aliphatic acids are produced by the oxidation by means of oxidizing gases of hydrocarbons which have been produced by hydrogenation of oxides of carbon for instance by the Fischer process.  The oxidation may be effected in the presence of catalysts such as heavy metal salts of unsaturated acids of the type CnH2n-xO2 in which n is greater than 15 and x is greater than 5.  In an example the initial hydrocarbon has a boiling-point above 250 DEG  C. and the oxidation is effected at 115 DEG  C. by means of air in the presence of a catalyst.  The product contains stearic, palmitic, myristic, lauric, and capric acids.  The Specification as open to inspection under Sect. 91 is not limited in respect of the boiling-point of the hydrocarbon to be oxidized but states that the melting-point of the hydrocarbon is preferably not above 50 DEG  C.  A table is given comparing the oxidation products of these hydrocarbons with the oxidation products of compounds produced by the hydrogenation of carbon. As oxidation catalysts there are mentioned compounds of metals such as manganese, nickel, vanadium, cobalt and calcium with oxygen such as per-compounds for instance potassium and sodium peroxides, potassium permanganate and salts of the metals mentioned with stearic, clupanedonic, oleic, and alkyl-sulphuric acids, and compounds of these metals with acetyl-acetone, acetoacetic ester and oximes.  To reduce the quantity of oxy-carboxylic acid, the product of oxidation may be treated with dissolved or solid substances having an alkaline reaction in quantity far below that required for saponification.  Six detailed examples are given, in two of which manganese clupanedonate, in one cobalt stearate and manganese peroxide, and in one potassium permanganate are used as catalysts. Specification 255,818, [Class 2 (iii)], is referred to.  This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 467,328.

Title: PROCESS FOR REGENERATING VOLATILE BASES AND WEAK ACIDS FRoM THE SALTS FORMED THEREWITH
Inventor: RENAULT PHILLIPPE
IPC: C01B32/50
Filed: 1968-02-13
Abstract: 1,211,436. Regeneration of bases and acids from their salts. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 13 Feb., 1968 [13 Feb., 1967; 30 March, 1967], No. 6994/68. Heading C2C. [Also in Division C1] Volatile bases and weak acids are regenerated from their salts in a process consisting of (I) contacting the salt with an organic base of low volatility in the liquid phase under conditions of temperature and pressure such that the volatile base is liberated as a gas substantially free from the acid and organic base, and (II) varying the temperature and/or the pressure so as to liberate the weak acid as a gas, and regenerate the organic base in the liquid phase. Numerous organic bases are specified and the organic base is used in the presence of a solvent in at least the first stage, a large number of organic solvents being mentioned. Examples include the regeneration by the process of ammonia, formic acid and acetic acid, carbon dioxide and hydrocyanic acid. The liberation of the weak acid and base is enhanced by sweeping the products away preferably using nitrogen to sweep the base in stage (I) and steam to sweep the acid in stage (II) The invention is illustrated by the application of the process to the continuous purification of smoke containing sulphur dioxide by reacting the sulphur dioxide with ammonia and regenerating the ammonia and sulphur dioxide by the method of the invention using a solution of triethanolamine in triethyleneglycol monoethyl ether as the organic base solution. The sulphur dioxide is extracted and the ammonia and organic base solution recycled.
