Title: Process for the manufacture of dispersoids
IPC: C09K23/00
Filed: 1920-12-24
Abstract: Dispersoids of lakes or other materials are obtained by pounding or rubbing the ground substance in a dispersion medium which is a non-conductor or a bad conductor of electricity, the moving surfaces having a velocity of not less than 1000 metres per minute. Dispersion may be assisted by adding solvent chemical agents, or those which form labile compounds with the substance to be dispersed or materials causing formation of unstable complexes between the dispersoid and dispersion medium.  Two constructions of grinding-mills in which the process is carried out are described. Specifications 17729/13, 17731/13, 17732/13, [all in Class 1 (i), Chemical processes &c.], 155,212, [Class 91, Oils &c.], 156138, 156,142, and 156,149, [all in Class 1 (i), Chemical processes &c.], and 156,156, [Class 46, Filtering &c.], are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) describes a further construction of mill, and also a filter for use in dry-grinding in vacuo.  This subject-matter does not appear in the Specification as accepted.ALSO:Dispersoids of graphite or other materials are obtained by pounding or rubbing the ground substance in a dispersion medium which is a con-conductor or a bad conductor of electricity, the moving surfaces having a velocity of not less than 1000 metres per min.  Dispersion may be assisted by adding solvent chemical agents, or those which form labile compounds with the substance to be dispersed or materials causing formation of unstable complexes between the dispersoid and dispersion medium.  According to an example, colloidal graphite is made by dispersing graphite with hot water, cooling, allowing to settle, decanting and drying. Potash olein soaps, tannin and phenol sulphonic acids may be used as dispersion accelerators.  A considerable acceleration of the process is obtained by working under vacuum.

Patent GB-817694-A (GB)
Title: Process for the regeneration of an aqueous caustic alkali solution containing mercaptides
IPC: C01D1/36
Filed: 1956-11-27
Abstract: An aqueous alkali metal hydroxide solution is freed from mercaptides by dispersing an excess of oxygen-containing gas under increased pressure in the solution in a reactor so as to oxidize the mercaptides to disulphides, passing the dispersion under substantially the same conditions of pressure and temperature to a separator, separating undissolved gas from the solution, passing the solution to a stripping column, and stripping with a gas inert to the solution and the disulphides.  The oxygen-containing gas may be air, oxygen, or a mixture of air and oxygen.  Dispersion may be effected by a turbo-mixer or propeller mixer.  Oxidation may be carried out at a pressure of 6 atmos. abs. and a temperature of 20-80 DEG  C. Stripping may be effective at a pressure of 1.5 atmos. abs. and a temperature of 80 DEG  C.  If the oxidation is carried out at a temperature of 20-40 DEG  C., e.g. 30 DEG  C., an unstable dispersion of disulphides is formed, and partial separation of the disulphides may be effected by means of a settling chamber, or centrifuge situated between the separator and stripping column.  The oxygen-containing gas from the separator may be used as the stripping gas.  The solution from the stripping column may be passed in heat exchange with the solution passing to the reactor or to the stripping column.
