Patent GB-389145-A (GB)
Title: Improvements in or relating to the manufacture of acetaldehyde
IPC: C07C45/38
Filed: 1931-09-12
Abstract: Water is removed from vapour mixtures containing acetaldehyde by treatment with a liquid at such temperature that water and preferably also alcohol is removed while the acetaldehyde remains in vapour form.  If water only is to be removed, the temperature may be between the boiling-points of alcohol and water, but if alcohol also is to be condensed, the temperature should be between the boiling-points of acetaldehyde and alcohol, such as 30-60 DEG  C. The vapours may be scrubbed by the liquid, for instance in counter-current, and vapour of the liquid may be mixed with the vapours, or the vapours may be introduced into a still column, the liquid or liquids being introduced at the top or at the top and bottom so that the acetaldehyde passes off from the top, which is maintained at or about the boiling-point of acetaldehyde. Alternatively vapours of the liquid may be added to the vapours, the mixture being cooled to condense all except the acetaldehyde. However the separation is effected, vapour of the liquid may be added to the mixture of alcohol and oxygen from which the acetaldehyde is produced, and this addition may be in large quantity, e.g. 1-5 times the alcohol vapour.  Other diluents such as nitrogen may also be employed.  Suitable liquids are benzene, petroleum hydrocarbons (petrol, petroleum ether and the like), acetone, and esters such as ethyl, propyl, isopropyl, butyl, and isobutyl acetate.  The liquids are preferably not miscible with water.  The acetaldehyde from which the water has been removed may be absorbed in an anhydrous solvent which does not interfere with its intended use, such as glacial acetic acid.  The oxidation of the alcohol may be effected with the theoretical quantity of oxygen or more or less, at 300-500 DEG  C. in presence of suitable catalysts such as silver, copper, or their oxides.  Specification 389,135 is referred to.

Title: Continuous method and apparatus for producing magnesium metal from magnesium chloride
IPC: C25C3/04
Filed: 1967-06-02
Abstract: 1,144,866. Electrolysis of molten magnesium chloride. NATIONAL LEAD CO. June 2, 1967 [June 8, 1966], No.25667/67. Heading C7B. In a continuous process for electrolytically producing Mg from MgCl 2 , the MgCl 2  is melted in a melt cell 15, mixed with other molten chlorides in a charging cell 26 and fed to a series of electrolytic cells E 1 -E x  from which the resultant Mg and electrolyte depleted in MgCl 2  are fed to a refining cell 31 where the Mg is separated from the electrolyte and the electrolyte then fed to the charging cell 26 where it is recharged with MgCl 2  and fed back to the electrolysis cells E 1 -E x . Chlorine gas evolved from the electrolysis cells passes through conduits C 1 -C x  to a manifold 40. The electrolyte composition may consist of 5- 25% MgCl 2 , 5-55% LiCl, the balance being chloride salts of ore or more of Ca, K and Na. For example the electrolyte may be 50% LiCl, 5% NaCl, 10% KCl, 20% CaCI 2  and 15% MgCl 2 , percentages being by weight. Substantially anhydrous MgCl 2  blocks 10 are fed to the melt cell 15 as also are HClcontaining hot gases which remove surface moisture from the MgCl 2 . In the melt cell 15, oxide impurities are electrolytically decomposed at 2 volts D. C. using carbon electrodes 21, 22 to produce CO. The melt cell 15, charging cell 26 and refining cell 31 are all heated by passing A. C. therethrough and scum can be removed therefrom using a device 24. As shown in Fig. 2, an electrolytic cell E x  comprises a steel tank 42 lined with brick 43. Pairs of steel cathodes 45, 46 and interposed graphite anodes 47 are supported by precast shapes 44 which rest on the main cell structure. Semiwalls 48, 49 separate the Cl 2  and Mg produced in the cell. The Cl 2  is removed through outlet ports 53 and the Mg together with some of the electrolyte is removed over a weir (57), Figs. 3 and 5 (not shown). During extended operation, the semi-walls 48, 49 break away along their lower edges. This may be compensated for by raising the level of the weir (57). The Mg and electrolyte is fed from the electrolysis cells to the refining cell 31, Fig. 1, where the Mg 37 remains on one side of a semiwall 36 whilst the electrolyte passes beneath it. A permanent flux cover 39 is maintained on the surface of the Mg 37. The electrolyte passes from the refining cell 31 to the charging cell 26 through a conduit 30. Fig. 4 (not shown) illustrates apparatus wherein a refining and charging cell are combined in a single unit (69).
