Title: Process for the purification of solutions containing soluble aluminates
IPC: C01F7/02
Filed: 1964-12-11
Abstract: Alkali metal, aluminate solutions, preferably Na aluminate solutions fron the Bayer process, are purified by passage over an anion exchange resin.  The resin may have active quaternary amine groupings, e.g. trimethylammonium, and may be based on polystyrene or styrene-divinylbenzene copolymers.  It may be 50% porous and have a surface area of 40-70 m.2/g. The aluminate solution at 20-40 DEG  C. is passed upwards or downwards through the resin so that the resin is kept in suspension, and may be recycled for further treatment.  The resin is then washed with water, regenerated with NaCl solution, and washed again.  A series of vessels may be arranged such that each of these steps is operating in series (Fig. 3, not shown).  Regeneration with a solution containing NaNO3 and NaOH may be performed every 10-20 cycles. Any alumina hydrate deposited on the resin may be removed by treating with NaOH solution or by draining the resin into a saturated CaCl2 solution and separating alumina from resin by their different densities.

Abstract: 1,171,636. Films. UNION CARBIDE CORP. 16 Nov., 1966, No. 51437/66. Addition to 979,630. Heading B5B. [Also in Division C3] A substantially transparent biaxially oriented composite thermoplastic film is composed of a mixture of at least two mutually incompatable synthetic organic resins, each being normally in an amorphous rubbery state at a temperature above its heat distortion temperature at 66 p.s.i. and said resins being orientable at a common temperature, said composite film having a shrinkage value of at least 5% along each of the major axes at a temperature of 50‹ C. above the heat distortion temperature at 66 p.s.i. of the polymer species present in an amount at least as great as any other polymer species present. Said film may contain an inert filler and/or pigment and suitably has a thickness no greater than 20 mils. Preferably, the polymer species present in an amount at least as great as any other polymer species present is high-density polyethylene, and the film may comprise an intimate admixture of polystyrene and high density polyethylene. Preferably, one of the resins is present in an amount of from 5 to 95% by weight based on the total weight of the resins, the composite film having a maximum shrinkage value of at least 20%, and especially at least 50%, in the direction of each major axis. In such a composite film, one of a total of two mutually incompatible resins may be present in an amount of from 5 to 50 weight per cent based on the total weight of the two resins. One of the mutually incompatible resins may be polystyrene, polymethyl methacrylate, polyethylene terephthalate or a polymer of vinyl chloride, especially a copolymer of vinyl chloride and vinyl acetate. A film formed from the mixture may be molecularly oriented by biaxially stretching in the direction of each of the two major axes in an amount of at least 50%, especially at least 200%. The process may further include a step in which a selected area of the film is made substantially opaque by preferentially heating the area to a temperature sufficient to permit oriented molecules within the area to relax, thereby causing localized shrinkage and the development of opacity, or by the application of a plasticizer for at least one resin component of the film. In the example, a mixture is made containing 50 parts linear polyethylene of density 0À965 and melt index 0À2, 30 parts unmodified polystyrene, 10 parts titanium dioxide, and 10 parts calcium carbonate, and is hot-compounded in a mixer and moulded into sheets which are stretched to a draw ratio of 4:1 at 265‹ F. yielding a film of 4 mils. thickness having a tensile strength of 11,000 p.s.i. and a tensile modulus of 250,000 p.s.i.
