Patent GB-590804-A (GB)
Title: Improvements relating to the manufacture of electrical insulating boards or slabs
IPC: H01B3/06
Filed: 1945-02-09
Abstract: An electrical insulating board or slab is made by forming a wet mixture of waterproofed asbestos fibres and a smaller weight of thermosetting resin into a coherent body and hot pressing this body so that the fibres are bound by the set resin.  The chrysolite, crocidolite or amosite varieties of asbestos may be used and the preferred waterproofing agent is asphalt.  As described, the fibre is waterproofed by passing it through a solution of asphalt in a mineral solvent, removing excess solution by squeeze rolls, and drying with recovery of solvent; it is then opened or fluffed by means of a mill, mixed with powdered phenol-formaldehyde resin and the mixture formed into a slurry with 10 times its weight of water which may contain a wetting agent.  The slurry is pressed to remove water and form a coherent body which is dried at a low temperature and then hot-pressed, for which purpose high frequency electrical heating methods may be used.  The boards so produced may be further heated in an oven to complete curing of the resin and remove any entrapped vapours. The boards may be 1/8 to 1 inch thick; if desired the coherent bodies may be dusted with the powdered resin, superimposed and then hot-pressed, to form a board as much as 4 inches thick.

Title: Hydrogenolysis process
Inventor: GOLDEN RICHARD LESLIE
IPC: C07C1/22
Filed: 1966-01-27
Abstract: Aralkanes are produced by hydrogenolysis of alpha-aralkyl alcohols in the liquid phase in the presence of a platinum group metal catalyst at a temperature above 50 DEG  C. but not above 120 DEG  C. The catalyst may be in elemental or combined form, e.g. as a halide, sulphide, sulphate, phosphate or double salt, and may be supported, e.g. on silica gel, magnesium carbonate, alumina, kieselguhr, carbon, barium sulphate or asbestos.  The alcohol may be derived from a process in which an olefinically unsaturated compound has been epoxidized by an alpha-aralkyl hydroperoxide which has itself been converted to the alcohol, and the aralkane product may be recycled to be converted back to the hydroperoxide. Examples describe the production of cumene, ethyl benzene, p-ethyltoluene, a -phenyl b -methylpropane, p-diisopropyl benzene and tetralin.ALSO:Propylene is epoxidized to propylene oxide by reaction, in the liquid phase and in the presence of Mo and Na naphthenates, with the hydroperoxides of cumene, ethylbenzene, p-ethyl toluene, a -phenyl-b -methyl-propane, tetralin and p-di-isopropyl-benzene. The alcohols corresponding to the hydroperoxides are recovered from the reaction mixture.ALSO:Platinum group metal catalysts which have been deactivated through use in a process whereby alpha-aralkyl alcohols are hydrogenated to the corresponding aralkanes are regenerated by a solvent wash, suitable solvents being the aralkyl alcohol or the aralkane involved in the reaction, or water, an ether, an ester, an acid, a ketone, or a different cyclic or acyclic hydrocarbon, e.g. benzene or toluene.  The catalyst may be in elemental or combined form, e.g. as a halide, sulphate, sulphide, phosphate or double salt, and may be supported, e.g. on silica gel, magnesium p  carbonate, alumina, kieselguhr, carbon, barium sulphate or asbestos.  In Examples, a Pd/C catalyst is regenerated by washing at 150 DEG C with cumene, ethylbenzene, p-ethyltoluene, p - diisopropylbenzene, alpha - phenyl-beta-methyl-propane or tetralin.
