Abstract: 896,113. Preparing hydrazine electrolytically. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 2, 1960 [May 7, 1959; Oct. 12, 1959], Nos. 15744/59 and 34578/59. Drawings to Specification. Class 41. Hydrazine is made by electrolysing liquid ammonia or a solution thereof in water or ethyl alcohol, in which a zone of vapour is maintained surrounding one electrode and in contact with the liquid whereby a glow discharge as distinct from a spark discharge, is generated and the ion formed pass into the liquid-forming hydrazine. In a modification, the electrode may be heated in the liquid to form a gaseous envelope surrounding it. A small amount of NH4 NO3 may be added to render the liquid conducting. A reduced pressure of about 100 to 250 mm. is required, and preferably in the case of liquid ammonia, a temperature a little above the freezing point (- 80‹ C.) is applied. A voltage of 400 to 900 v. is applied to the electrodes, and the electrode or series of electrodes, e.g. anodes, above the liquid surface is momentarily lowered to touch it and then raised 0.5 cm. to generate the vapour envelope at reduced pressure. Pure dry hydrazine is separated by distilling off the ammonia. Solutions of ammonia produce aqueous hydrazine solutions which may be used as such or the hydrazine separated as sulphate by adding H2SO4.

Separators. - Apparatus for purifying air, drying and straining steam, separating acids and soot from waste gases, and like processes comprises undulating passages formed by separating walls which are orescent-shaped in cross section. Fig. 6 shows three sets of solid crescent-shaped blades forming undulating passages in the chamber 7 through which the gases pass. Figs. 2 - - 5 show various modifications of the shape of vanes made of cast or sheet metal and arranged so that the dotted bounding lines enclose a crescent-shaped area. The recesses between the. teeth of these formations form collecting pockets for the removed material. In a further modification, more especially for drying and straining steam and vapours, separating elements of the form shown in Fig. 4 are arranged so that the entrances for the gas to the separation passages are in the form of broadened laval nozzles extending in diffusor-like manner towards the separation passage. Pieces cast on to the ends of the separating members form the nozzles, and also form supports for the next separating member of the series. In other modifications for treating atmospheric air, including that supplied to internal-combustion engines, liquid is siphoned from a tank by depending wicks or expressed therefrom by a screw-actuated pressure plate so as to drip down between the ribs of the separating members and come into direct contact with the air. In another modification the liquid is ejected through the front edges of the vanes against the incoming stream of gas. In a further modification the vanes are arranged on the periphery of tubes through which the water circulates. A heating or cooling as well as moistening and cleaning affect can be effected under these circumstances.

Title: Extractive distillation with salt solutions
IPC: C07C29/84
Filed: 1948-06-15
Abstract: <PICT:0647927/III/1> Water-soluble alcohols having close-boiling aqueous azeotropes are separated from each other by passing the mixture, which may contain other oxygenated organic compounds and also hydrocarbons, into the side of a fractionating column, and introducing an aqueous solution of a salt into the column above the feed level to make the salt solution content of the internal reflux at least 50 mol. per cent and sufficient to alter the relative volatilities of the components of the feed-mixture so that the alcohol of lowest molecular weight dissolved in the aqueous salt solution and free from the other organic components of the feed mixture, is withdrawn from the base of the column while the vapours of the other components are withdrawn overhead.  Suitable salts are sodium acetate, disodium hydrogen phosphate, sodium carbonate, and magnesium chloride; but many others are referred to.  The process is applicable to the separation of alcohols obtained by mixedolefine hydration, by Fischer synthesis, and by hydrocarbon oxidation; cuts of 5 to 10 DEG  C. boiling range, obtained by conventional distillation, being used as feed mixtures.  In an example, a mixture containing ethyl alcohol, isopropyl alcohol, methyl ethyl ketone and water, was fed through line 1 at 650 gallons per hour into column 2 which was equivalent to 70 plates; and an aqueous solution at 190 DEG F. containing 9.7 mol. per cent sodium acetate was supplied at 3680 gallons per hour through line 3.  The fractionation conditions were adjusted so that the bottoms from column 2 was a dilute solution of ethyl alcohol in aqueous sodium acetate, while the distillate contained all the isopropyl alcohol and M.E.K. in the feed together with water and a small proportion of ethyl alcohol.  The bottoms from column 2 were passed through line 12 into column 13 from which the aqueous ethanol azeotrope was withdrawn overhead.  The aqueous sodium acetate leaving the base of column 13 was freed from dilution water (from the feed mixture) by heater 18, dephlegmator 24 and steam-exit line 23; and then returned to column 2 through heat-exchanger 25 and line 3.
