Title: Process for the selective hydrogenation of olefinic compounds containing a vinyl group
IPC: C07C5/03
Filed: 1959-12-21
Abstract: The selective hydrogenation of olefinic compounds containing a vinyl group in the presence of an olefinic compound not containing a vinyl group is effected with hydrogen in the presence of a ruthenium catalyst.  Suitable conditions are 0 DEG -200 DEG C. and subatmospheric-2,000 p.s.i.g. pressure, and generally the reaction is effected in the presence of 1-99% (based on the olefines) of water. The catalyst may be a sponge or supported on carbon, alumina, kieselguhr or diatomaceous earth. Sufficient hydrogen is added to hydrogenate the vinyl compound. The olefinic compounds may contain hydrocarbon or non-hydrocarbon groups which do not react under the conditions employed, e.g. alkyl, aralkyl, aryl, heterocyclic, hydroxyalkyl or ester.  The process may be used to effect separation of close boiling isomeric olefinic compounds.  The following selective hydrogenations are specified, in each pair of named compounds the first named is hydrogenated while the bracketed compound is unchanged:-1-octene (2-octene); 1-octene (cyclohexene); 4-methyl-1-pentene (cyclohexene); 4-methyl-1-pentene (2-octene); 1 - octene (2-methyl-1-pentene); 3 - methyl - 1 - pentene (2-methyl-1-pentene); 1-octene (2-methyl-2-pentene); 4-methyl-1-pentene (2-methyl-2-pentene); allyl benzene (a -methyl styrene); vinyl cyclohexane (1,2-dicyclohexylethylene); 3-vinylpyridine (1-(3-pyridyl)-propene); 1-buten-4-ol (2-methyl-1-buten-4-ol); acrylic acid (crotonic acid).

Abstract: 1400424 Preparing polymer/plasticizer compositions W R GRACE & CO 18 Sept 1972 [17 Sept 1971 (2)] 43576/71 and 43582/71 Heading C3P A polymer composition is prepared by mixing (i) an aqueous polymer emulsion with (ii) a dispersion of a desiccant in a plasticizer for the polymer, the relative amounts of (i) and (ii) being such that the plasticizer forms the continuous phase in the composition. The desiccant is defined as being any solid or liquid material which acts as a desiccant and chemically and/or physically adsorbs the water present, thus converting it into a non-evaporable form at ambient temperature and pressure. Examples are silica gel, a calcium sulphate plaster, BaO, CaO, CaCl 2 , an ortho ester such as trimethyl orthoformate, or a molecular sieve. Examples of polymers whose emulsions may be treated are elastomers and thermoplastics such as PVC, polystyrene, polyacrylates and polyolefins. Suitable plasticizers are chlorinated di- or ter-phenyls, hydrocarbon oils, coal tar and petroleum derivatives such as bitumen, esters, chlorinated paraffins and paraffin waxes, vegetable oils and polyisobutylene. The composition may be formulated so that it sets, and can thus be used like a putty, or for moulding. It can also be used as a coating composition for substrates such as fabrics, meshes, metal foils, plastics, fibres, plaster board and sheets made from fibrous asbestos, glass, mica and metals, and to form self-supporting films or sheets.

Abstract: 1,011,532. Hydraulic transmission of power; bearings; variable-speed gears. MASSEYFERGUSON Inc. Dec. 14, 1961 [Dec. 29, 1960], No. 44716/61. Headings F2A, F2C and F2D. [Also in Division F1] An hydrostatic rotary power transmitter comprises a pump component P and motor component M bearing and thrusting against stationary valve surfaces 75, an auxiliary hydraulic thrust bearing 76 on each of the pump and motor valve surfaces, hydrostatic pressures being created in said bearing by rotation of the pump and motor, and an hydraulic connection between the bearings through which fluid can flow from one bearing to the other. The pump and motor are of the swashplate type having bodies 25, 45 receiving pistons 31, 50 which have ball elements 32, 51 engaging thrust rings 33, 53 on non-rotatable swashplates 34, 55, the angle of the swash-plate of the pump being adjustable. The cylinders 30 in the body 25 communicates through ports 36, 48 and arcuate suction and discharge passages 60, 61 in the valve plate with cylinders 46 in the body 45. The bodies are urged towards the valve plate by springs 38, 66 and both surfaces 75 of the valve plate have thrust bearings 76 consisting of arcuate segments, each segment being formed with a pair of shallow channels 79 which are disposed between sealing surfaces 75 and separated by a land 77 in the same plane as the surfaces 75. During rotation of the pump or motor bodies relative to the valve plate, fluid in a sump 12 for the transmission passes through inlets 81 between the segments and is pumped by the viscous drag between the surfaces of the channels and the adjacent pump or motor body to relatively deeper channels 80 wherein the hydrostatic pressure of the fluid acts as an auxiliary bearing between the valve plate and adjacent body; the provision of the land 77 between the two channels in each segment enables the hydrostatic bearing pressure to be obtained irrespective of the direction of rotation of the transmission. The deeper channels 80 in the bearings on one side of the valve plate are hydraulically connected to those on the other side by passages 83 whereby in the event of one body rotating at a lower speed than the other, the pressure in the channels is equalized. Leakage of fluid is made up by connecting the suction passage 60 by a pipe 69 and valve in a block 70 to the fluid in the sump. The discharge passage 61 is connected by a pipe 72 to a by-pass in the valve block 70. The inlet shaft 14 of the pump is connected to a flywheel 16 and by gearing 23, 22 and a shaft 21 to an epicyclic gear unit 19 connected to the motor shaft 18 and an output shaft 20, the gear unit combining the power from an engine connected to the shaft 21 with the output from the hydrostatic transmission.

Abstract: 1,211,072. Torsional vibration dampers. POWDER COUPLINGS Ltd. 9 Oct., 1967 [7 Oct., 1966], No. 44984/66. Heading F2S. A torsional vibration damper for a rotary shaft consists of a circular section housing 4 and which is capable of free rotation with respect to a member 8 which is mounted within the housing for rotation relative thereto about the housing axis. The housing also contains particulate solid material such as metal shot 9 which constitutes friction coupling means between the member 8 and housing 4 so that when the member 8 is driven by a shaft 2 the housing 4 rotates with it. The frictional coupling torque varies with rotational speed in consequence of the dependence of closeness of packing of the shot on centrifugal force. If, at a particular speed of rotation, the housing and member 8 are rotating together there is no tendency for the shot particles to rub against each other, but a change in rotational speed of the driven member will disturb this equilibrium and cause energy to be dissipated by friction between the shot particles. Thus torsional oscillations of the driving shaft will be frictionally damped. An outer cover 11, Fig. 2 (not shown), may be secured to the hub 1 of the member 8 and surround and enclose the housing 4.
