Title: Improvements in or relating to the separation of nickel from cobalt
Inventor: MERRE MARCEL DE
IPC: C01G51/00
Filed: 1954-09-06
Abstract: Cobalt and nickel, present in solution as sulphates or chlorides (or ammoniacal complexes thereof) in a weight ratio of Ni-Co greater than 2/1 , are separated by treating with a reducing gas under super-atmospheric pressure and a temperature above 100 DEG C., and stopping the reduction while the metallic nickel which precipitates contains less than 2, preferably less than 0.5, parts by weight of Co per 100 parts by weight of Ni; separating and treating the solution with iron and/or cobalt, an alloy of iron and cobalt or an alloy of iron and/or cobalt and another metal or metals in the presence of S, Se, Te, As or Sb (as described and claimed in Specifications 650,595, 655,149 and 683,679) to produce a practically Ni-free cobalt solution and a residue which is then brought into solution in the form of sulphates or chlorides and added to the original solution.  In the example an ammoniacal sulphate complex was treated with hydrogen in an autoclave at 120 DEG C. and 70 atmospheres; the pH was adjusted to 3 and maintained below 5 with sulphuric acid whilst treating with Co and S in powder form; the final residue was subjected to a sulphatizing roast at 550 DEG C., dissolved and converted into ammoniacal complexes before recycling.ALSO:Nickel is precipitated from solutions of sulphates or chlorides of nickel and cobalt (or ammoniacal complexes thereof), wherein the weight ratio of Ni/Co is higher than 2/1, by treating with a reducing gas under pressure and an elevated temperature, reduction being stopped while the metallic nickel which precipitates contains less than 2, preferably less than 0.5 parts by weight of Co per 100 parts by weight of Ni.  The remaining solution is treated to obtain a cobalt compound in pure form (see Group III) and recycled.  In the example an ammoniacal sulphate complex was treated with hydrogen in an autoclave at 120 DEG C. and 70 atmospheres.  Specifications 650,595, 655,149 and 683,679, [all in Group III] are referred to.

Title: Improvements in the bleaching of soaps and soapstocks
Inventor: JAMES FREDERICK OLIVER
IPC: C11D13/06
Filed: 1951-11-09
Abstract: <PICT:0713029/III/1> Soaps and soapstocks are bleached by continuously feeding a hypochlorite bleaching agent into a stream of molten soap or soapstock and ensuring rapid and intimate mixing of the bleaching agent with the soap or soapstock.  The soaps &c., specified comprise those made mainly from highly coloured oils such as red palm oil and green tallow soaps, groundnut oil soapstock containing the soap mixed with neutral oil, and palm oil soapstock. The bleaching agent is preferably sodium hypochlorite and includes substances such as chlorine which will form a hypochlorite in situ when a caustic alkali is present.  A bleaching aid may also be used and may be fed either into the intimate mixture of the soap and bleaching agent or into the stream of molten soap.  The bleaching aids specified comprise per-salts such as sodium persulphate or sodium percarbonate, peroxides such as hydrogen peroxide, oxygen, ammonia, ammonium salts or urea.  The process may be carried out under pressure, usually not exceeding 5 atmospheres.  A preferred temperature is 75 DEG  to 85 DEG  C., but temperatures up to or above 100 DEG  C. may be used by operating under pressure and using steam. In the case of soapstocks, saponifying and bleaching in one operation may be effected by bleaching in the presence of an alkaline substance. The process should be carried out under alkaline conditions by adding alkali so that the pH does not fall below the desired value as the reaction proceeds.  In a suitable apparatus for the process, water, bleaching agent, bleaching aid and molten soap or soapstock are fed at the bottom of a tubular vessel 8 through pipes 1, 2 3 and 4 respectively.  The liquids are agitated by an agitator 10 having three blades preferably close to the outlets of the feeding pipes, with additional stirrers at other levels if desired, operated by a motor 11 through a shaft 12.  A heating or cooling jacket 9 may be provided.  The outlet 7 for the bleached soap is provided in the upper part of the vessel.  Detailed examples of the process are given, in some of which a subsequent treatment with sodium hydrosulphite is used.

Class 9(2) Pyrotechnic devices are manufactured by adding combustible substances. obtained by soaking materials containing cellulose or starch in oils or fats, e.g. oily hydrocarbons, to a molten mixture heated to 90‹C at least and containing 50 per cent ammonium nitrate, less than 10 per cent flamecolouring compounds and 2 per cent to 5 per cent of water, these proportions being related to the final ,mixture. The mixture is then allowed to solidify while being continuously stirred and, on solidification, is granulated, then pulverized, the resultant powder then being pressed to the desired shapes. The final shaping may be carried out at room temperature or the powder may be heated to the melting temperature of the fatty substance incorporated. Prior to granulation, the composition may be heated to remove surplus water. An organic binder may be incorporated in the composition. When strontium compounds are used as flame-colours, up to 15 per cent may be incorporated. A paste of hexamethylene tetramine, metaldehyde, paraformaldehyde or other inflammable substances combined with an anhydrous solvent and binder may be applied to the final shapes as an ignition composition. In a composition containing 2000 parts ammonium nitrate, 180 to 270 parts of molten stearin are mixed with 50 to 100 parts of wood dust. The ammonium nitrate is melted at 125‹C, 60 to 150 parts of cupric acetate and 2 per cent to 5 per cent of water being added. In all cases the proportions are by weight. The soaked wood dust is added, the mixture being stirred and cooled. The cake formed is then granulated and subsequently ground, the powder obtained being pressed at room temperature into candles. A coating of green paraffin or varnish is then applied to indicate the flame colour. In a second example, the solid cake is pressed at a temperature between 90‹ and 120‹C before grinding. In a third example half the wood dust is replaced by potato starch, or rye or wheat flour. The stearin may be replaced by paraffin or lubricating oil.
