Patent GB-839690-A (GB)
Title: Process for recovering hydrazine
IPC: C01B21/16
Filed: 1956-08-24
Abstract: <PICT:0839690/III/1> Anhydrous hydrazine is recovered from an anhydrous liquid mixture containing hydrazine, a hydrohalide salt of a base which is displaceable therefrom by hydrazine, for example ammonium chloride, and ammonia, by maintaining in the system an amount of ammonia sufficient or in excess of the amount required to prevent the decomposition of the hydrohalide salt, and withdrawing from the system vaporized constituents, comprising hydrazine and ammonia, which are then resolved, for example by condensing the hydrazine without condensing the ammonia.  The amount of ammonia present should preferably be at least sufficient to maintain the hydrohalide salt in solution.  An anhydrous mixture of the above type may be obtained by reacting gaseous chlorine with gaseous ammonia to form chloramine, and reacting this with anhydrous liquid ammonia to form hydrazine and ammonium chloride, as described in U.S.A. Specification 2,710,248.  Ammonia may be withdrawn from such a mixture by maintaining the temperature between the boiling-point of ammonia and 80 DEG  C. and the pressure between 7.4 and 13 kg/cm2 absolute, thereby concentrating the mixture with respect to hydrazine and ammonium chloride.  The resultant mixture is heated to a temperature not exceeding 130 DEG  C., the vapour above the mixture is continuously withdrawn and fractionated into hydrazine and ammonia, which latter may be continuously returned to the mixture. In one embodiment of the invention, a hydrazine-ammonium chloride-ammonia mixture concentrated with respect to hydrazine and ammonium chloride is passed downwardly through an extraction column 27, maintained at 80-130 DEG  C. and at a pressure between 21 and 35 kg./cm.2, in countercurrent to a stream of gaseous ammonia.  The liquid issuing at 28 is practically free of hydrazine, and the gas stream 34, consisting of ammonia and hydrazine, passes into fractionator 35, from which ammonia issues at 36, and may be returned to column 27 via compressor 38 and heater 39.  The hydrazine product stream 40 passes to still 42 where residual ammonia is removed. Between 400 and 1000 mols. of ammonia are required in the column for each mol. of hydrazine to be removed.

Filed: 1960-07-28
Abstract: 932,458. Mercury switches. TECHNIKUM PO ELEKTROTECHNIKA S. M. KIROV. July 28, 1960, No. 26250/60. Class 38 (5). A switch comprises a glass tube A containing an electrolyte 5 and a mercury drop 6, the electrolyte 5 being connected through electrodes 1,2, to a D.C. primary circuit, closure of which causes the drop 6 to move towards the negative electrode 1 and bridge electrodes 3, 4, so closing a secondary circuit. Opening of the primary circuit allows the drop 6 to be restored to its original position by gravity. In a modification, Fig. 2, the drop 6 coheres to the roughened surface of electrode 2 so that upon passage of primary current the drop elongates to bridge electrodes 3, 4, restoration being effected by the surface tension of the drop 6 with or without the aid of gravity depending on the position of the tube A. In another modification, Fig. 3 (not shown) the tube has a pair of secondary electrodes at each end, each pair facing a recess in the flat, horizontal base of the tube, so that a mercury drop bridges either pair according to the direction of primary current, and remains in the corresponding recess until the primary current is reversed. The electrolyte may comprise diluted sulphuric acid, organic salts dissolved in water, ether or alcohol, or a solution of acid, base or salt in a suitable solvent. Instead of an electrolyte, a semi-conducting mixture, a gas or a vapour may be used. A plurality of mercury drops may be used, in which case the tube has partitions to prevent the drops coalescing.
