Title: Process for the extraction and separation of oxytocin and of vasopressin from the posterior lobe of the pituitary
IPC: A61K38/095
Filed: 1952-06-06
Abstract: The hormones oxytocin and vasopressin are extracted from the posterior lobe of the pituitary by treating the said lobe, or a dry extract thereof, with a dilute (2 per cent or less) aqueous solution of an organic acid, e.g. acetic, propionic or tartaric acid, absorbing the hormones on activated silica, and then treating the absorbent with a dilute aqueous solution of an organic acid, preferably the same as as previously used, to obtain an eluate containing the oxytocin and a residue containing the vasopressin. For the extraction of the former, the eluate is preferably first freed from ferrous ions present by treatment with a-di-pyridyl, cupferron, sulphocyanides, oxyquinolines, &c. which form non-ionized complexes, then concentrated in carbon dioxide at 5 DEG C or lower, and the a-dipyridyl extracted with ether; then, it is preferably extracted with secondary octanol or chloroform to eliminate lipoids and pigments; finally, after being made slightly alkaline with ammonia, it is extracted with n-butanol saturated with water.  Water is eliminated from the extract by freezing at -60 DEG C, then ammonia by vacuum treatment in a current of nitrogen, and finally the butanol by distillation at 25-30 DEG C in nitrogen at 1/10-1/50mm. pressure. The concentrate is extracted with 0.1 per cent acetic acid, the extracted solution washed with chloroform, and the latter removed by bubbling in nitrogen.  The solution is finally treated with a bacteriostatic, e.g. chloretone.  For the extraction of the vasopressin, the silica is rendered alkaline, below pH 10, by ammonia, and then treated with a solution of an electrolyte, e.g. sodium chloride or sulphate containing an organic acid and preferably a surface active agent to produce a solution of the hormone.  The electrolytes are precipitated by ethyl alcohol which is removed by distillation. The solution of vasopressin may be further purified by treatment with a water-insoluble solution of an aromatic acid, e.g. salicylic, in a water-miscible solvent, e.g. acetone.  The acid precipitated absorbs the vasopressin, and it is then extracted by a mixture of water and ether, the hormone passing to the aqueous phase. The solution may be purified by extraction with n-butanol saturated with water and containing 1 per cent salicylic acid. The activated silica employed may be obtained by the process disclosed in Specification 714,378, [Group III].

Title: Production of alpha:omega glycols
Filed: 1966-04-01
Abstract: Preparation of an a ,o -glycol by subjecting a cyclic mono-olefin in a protonic liquid medium to ozonolysis and thereafter catalytically hydrogenating the resulting product preferably in a single hydrogenation stage.  In particular compounds of the formula HO.CH2.R.CH2.OH wherein R is an alkylene group containing 3 to 10 carbon atoms are prepared from the corresponding cyclic mono-olefins. The protonic liquid medium may be water, an aliphatic carboxylic acid such as a lower aliphatic mono-carboxylic acid (e.g. formic or acetic acid), a lower alkanol (e.g. methanol) or a mixture of two or more thereof. The protonic liquid medium may also be mixed with an inert solvent such as acetone or carbon tetrachloride. Ozonolysis is effected by conventional means using an ozone-containing gas, which is preferably an oxygen stream containing 1 to 20 volume per cent of ozone, at a temperature above the freezing point of the reaction mixture in the range from room temperature to - 100 DEG  C. Hydrogenation of the resulting product, which is believed to be an acyl hydroperoxide capable of being reduced to the desired a ,o -glycol or a diester thereof, is carried out in known manner in the presence of a hydrogenation catalyst at elevated temperature and under a pressure from atmospheric to 10,000 p.s.i. Conventional metallic hydrogenation catalysts, e.g. ruthenium, cobalt or nickel, optionally supported on a suitable carrier are used. 1,8-Dihydroxyoctane, 1,10-dihydroxydecane and 1,12-dihydroxydodecane are obtained from cyclooctene, cyclodecene and cyclododecene respectively.

Abstract: 1,101,563. Semi-conductor devices. GENERAL ELECTRIC CO. 8 April, 1965 [28 May, 1964], No. 14926/65. Heading HlK. The surface of a diamond is made semiconducting by exposing it to ionic bombardment produced by a brush discharge in a gas. The anode and cathode of the discharge apparatus may be of nickel or molybdenum and the cathode, on which the diamond rests, may be agitated to expose the whole surface of the diamond to the gas ions. The processed diamond is found to be coated with a film of sputtered cathode metal which is removed with aqua regia. A surface layer of the diamond is found to be quasi-amorphous and exhibits semiconductivity. Several examples are given, an atmosphere of nitrogen or argon producing an N-type surface, an atmosphere of hydrogen producing a P-type surface, and an atmosphere of helium or oxygen producing a resistive surface. An N-type surface layer may be produced in a P-type diamond doped with aluminium, indicating the possibility of producing diodes and transistors. On heating for a short time at a high temperature and pressure, or for about an hour at 300 to 400 C., in air, the diamonds lose their semi-conductive properties. Diamonds treated with a hot mixture of sulphuric acid and potassium nitrate to remove any graphite, amorphous carbon, or other non- diamond impurities from the surface increase in resistivity without losing their semi-conductive properties. It is stated that diamonds merely containing hydrogen or nitrogen as an impurity do not exhibit semi-conductivity.
