Title: The manufacture of unsaturated diketones related to the corpus luteum hormone
IPC: C07J5/00
Filed: 1934-09-03
Abstract: Pregnendiones are produced by oxidation of pregnenolones.  The oxidation may be carried out on the pregnenolone itself, or the double bond may be first protected by saturation with halogen, for example, bromine, and the halogen removed after oxidation to regenerate the pregnendione.  Examples in which direct oxidation is employed are: (1) Pregnenolone as obtained for instance according to the process described in Specification 443,964 is treated in glacial acetic acid with chromium trioxide at 15 DEG  C. for 2 days.  Instead of chromium trioxide, Beckmann chromic acid mixture can be used.  (2) Pregnenolone is oxidized by fusion at about 300 DEG  C. with \ba1/5\be of its weight of powdered copper oxide, or by shaking with lead dioxide in dilute hydrochloric acid.  (3) Pregnenolone is treated with alkaline alcoholic hydrogen peroxide.  Examples in which the double bond is protected by halogen are: (4) Brominated pregnenolone is shaken with aqueous acid permanganate, and the pregnendione isolated by the action of zinc dust in glacial acetic acid.  (5) Brominated pregnenolone is oxidized in the cold with chromium trioxide, and debrominated by treatment with zinc dust.

Title: Improvements in processes for separating oxygen and nitrogen and in apparatus therefor
IPC: B04B5/08
Filed: 1920-09-03
Abstract: 152,643. Zack, M. Oct. 15, 1919, [Convention date]. Density apparatus.-Oxygen and nitrogen are separated from a mixture in a centrifugal machine, and while subjected to centrifugal action they are cooled and subjected to the action of a rotating non-uniform magnetic field. The mixture enters the machine by the pipe 6 and passes through the centrifugal blower 2 driven by the electric motor 1. A hollow ring 4, filled with liquid air, carries electro-magnets 4<1> and rotates with the blower. A similar ring 10 with electromagnets 10<1> is attached to the hollow shaft 9 of a centripetal pump 8 driven by an electro-motor 11. Under the combined influence of centrifugal force and the magnetic field, oxygen is thrown outwards and carried along the ring 4, while nitrogen passes into the pump 8 through the hollow shaft 9 to the outlet 13. The oxygen passes across the magnetic field along the ring 4 and then along the ring 10. Some of the oxygen liquefies and is drawn off :'rom the outlet 12<1> and the remaining gas from the outlet 12. In order to permit the oxygen to leave the ring 4 and pass to the ring 10, the current in the electro-magnets is periodically interrupted, and at the same time the valves 14, 15 are partially or wholly closed. Instead of using revolving magnets, fixed magnets may be used supplied with polyphase current to give a rotating field.

Title: Process for the production of high-grade products from raw material containing pit coal or brown coal
IPC: C10L9/00
Filed: 1951-11-02
Abstract: A process for the removal of the ash content and for the dewatering of raw material containing pit coal or brown coal, such as sludges, dusts, intermediate material and impure coals, comprises mixing the raw material in fine or ultra-fine particle form with oil-containing substances, such as oil, tar or bituminous substances, such admixture being effected in the presence of a quantity of liquid, preferably water, sufficient to form a dispersion of the waste particles and of the oil-wetted coal particles and the conditions of mixing being such that little or no aggregation of the coal particles takes place, such dispersion then being mechanically, preferably centrifugally, separated, with simultaneous dewatering of the coal concentrate, into coal concentrate and waste liquid containing the bulk of the waste components of the raw material.  Diffusion may be effected in a beater mill or centrifugal mill, and, during admixture, the mass may be subjected to pressure, centrifugal action or suction by passage through high speed baffle plate mills having a delivery slot, or high-speed or high-pressure pumps having attached nozzles or venturi tubes.  Separation is preferably effected in a sifting centrifuge. The process may be carried out at elevated temperature and the pH value of the solution may be adjusted: froth flotation reagents may also be added.  The water content of the raw material may be adjusted by the addition, or extraction, of water or by adding dry coal, sifter dust or breeze.  The process may be repeated on the concentrates or on the waste, or may be combined with other known processes e.g. flotation, cyclonic separation, and particularly with processes for the preparation of ultra-pure coal such as flotation methods, heavy liquid processes and electrostatic processes, the tailings or concentrates from which may be subjected to the present process. Alternatively, by using a very small quantity of oil, the process may be used as the first stage in the preparation of ultra-pure coal, the concentrates and tailings being then separately retreated by the same process.  In a further alternative, coal is separated by a heavy liquid process and the components of finest grain size separated from the sinks and floats, these components being subjected separately or in common to the present process: the waste particles obtained form a suitable loading medium for the heavy liquid and the latter may be regenerated by the use of the present process.  Specification 183,430, [Class 82(ii)], is referred to.

Abstract: 1,219,830. 5-(2-Methoxyethyl)-furfuryl chrysanthemate. YOSHITOMI PHARMACEUTICAL INDUSTRIES Ltd. 31 May, 1968 [7 June, 1967], No. 26140/68. Heading C2C. [Also in Division A5] Novel 5 - (2 - methoxyethyl) - furfuryl chrysanthemate is prepared by reacting chrysanthemic acid or one of its functional derivatives with 5-(2-methoxyethyl) furfuryl alcohol or the corresponding halide. For example the ester is prepared by reacting chrysanthemoyl chloride with 5-(2-methoxyethyl) furfuryl alcohol in a solvent such as petroleum, benzene or dimethyl sulphoxide in the presence of an acid acceptor such as pyridine, diethyl aniline, triethylamine or potassium carbonate for ¢-24 hours; the mixture may then be heated to complete the reaction. Similarly the ester may be formed from the anhydride, or the free acid in the presence of a catalyst such as boron trifluoride, p-toluene sulphonyl chloride or ptoluene sulphonic acid. An ester exchange reaction between methyl or ethyl chrysanthemate and the above alcohol in the presence of potassium carbonate, sodium ethoxide or aluminium isopropoxide, under reduced pressure also yields the novel ester. Sodium chrysanthemate and 5-(2-methoxy ethyl)-furfuryl chloride in the presence of an acid acceptor may also be used to produce the ester.
