Patent GB-599270-A (GB)
Title: Improvements in or relating to the production of stable soaps and fatty acids from fatty materials
IPC: C11C1/00
Filed: 1945-05-15
Abstract: Materials containing oleic acid and linoleic acid, either in the uncombined form or in the form of esters such as glycerides, are saponified and the alkali salts of the acids thus obtained are heated with at least two mols of alkali in excess of that required to saponify the acids to about 280-305 DEG C, the heating being carried out substantially in the absence of oxygen and at a pressure not substantially above atmospheric pressure.  Stabilised soaps are thereby obtained since the unstable soaps of linoleic acid and any other polynnsaturated acid which may be present are decomposed by the treatment.  Materials containing oleic acid and linoleic acid which may be treated include tallow, palm oil, olive oil, menhaden oil, linseed oil, cottonseed oil, corn oil and commercial oleic acid. During the treatment, soaps of linoleic acid are converted to soaps of myristic acid and on acidifying the stabilized soaps, for example with sulphuric acid, a mixture of fatty acids free from linoleic acid is obtained.  Oleic acid may be recovered in a stable, pure or substantially pure state from this mixture of fatty acids by fractional crystallization or by neutralizing with a suitable lead compound to form lead soaps and extracting with ether or other solvents which dissolve the lead oleate but not the other soaps. Myristic acid may also be recovered from the mixture of fatty acids, for example by fractional crystallization or fractional distillation. Alternatively the mixture of fatty acids may be used in the manufacture of soaps, alone or blended with other oils, fats or fatty acids.  Or, again, the mixture of fatty acids or any component thereof may be reesterified with glycerine to form a synthetic oil. In examples, the fatty materials treated are (1) fatty acid methyl esters made by alcoholysis from tallow or (2) a mixture of methyl oleate, methyl linoleate and methyl stearate obtained from cottonseed oil fatty acids by alcoholysis or ester interchange followed by fractional distillation.  These are saponified with a mixture of caustic potash and caustic soda and the saponification products heated under an inert atmosphere with an excess of the alkali mixture.  The fatty acid mixture obtained by acidifying with sulphuric acid may be neutralised with caustic soda.  The Specification as open to inspection under Sect. 91 refers to a process of stabilising mixtures of fatty acids containing oleic acid and at least one polyunsaturated fatty acid which comprises heating an alkali salt of the acids in the presence of excess alkali, to the conversion temperature of linoleic acid but not to the conversion temperature of oleic acid.  This subject-matter does not appear in the Specification as accepted.

Title: Process and Apparatus for Separation of Suspended Particles from Gases.
Inventor: BURNS HERBERT ALEXANDER
IPC: B03C3/53
Filed: 1917-08-27
Abstract: 118,334. Burns, H. A. Aug. 27, 1917. Ammonium salts.-Ammonia in coal gas is absorbed in water or acid, or nitric acid mist is deposited into dilute ammonia, in apparatus in which the gas is passed through an undirectional electric field, and charged particles are received by a. stream or film of liquid. This liquid may flow continuously or intermittently over the surface of one electrode, which may be of metal. concrete, or an acid-resisting material such as terra-cotta, the liquid giving it sufficient conductivity. A smooth collecting surface is thus maintained on the electrode. In one form of apparatus, tubular wet electrodes 1 surround charging electrodes 3 of wire, which are attached to an upper cross bar 5, weighted at their lower ends, and spaced by an insulating bar 7 resting on the weights and connected to an insulated bracket 8. At the upper end the outer electrodes 1 are enlarged, and at the lower end the wires 3 may be thickened, to diminish local discharge. Current is supplied through a rectifier 25 by a transformer 26. Inlet pipes 10 discharge liquid tangentially, preferably around ledges formed in the outer electrodes. Collecting troughs 16 in the roof of the gas supply chamber 2 are shaped so as to form rounded inlet nozzles for the gas and so that the liquid falls clear of the connexions of the axial electrodes. The liquid serves to seal the bottom of the gas chamber 2. In a modification, a false roof collects the liquid and has wide funnel-shaped openings for the passage of gas into the tubular electrodes. In another form of apparatus, parallel wires are situated in planes between flat electrodes over which the liquid streams. Additional pipes are provided so that the wires also can be washed when not charged electrically. The apparatus is heated or cooled when necessary in order to prevent solidification or evaporation of the liquid. Specification 107,389, [Class 1 (i),'Chemical processes &c.] is referred to.
