Title: Production of hydrogen peroxide
Inventor: HOOPER GEORGE WALLACE
IPC: C01B15/12
Filed: 1963-07-23
Abstract: Cyclohexane is oxidized to cyclohexanol and hexanone, benzene to phenol and aromatic, cycloaliphatic or olefinic hydrocarbons to a phenol, an alcohol or a glycol respectively by the action of hydrogen peroxide prepared by reacting hydrogen and oxygen in an aqueous medium containing a solid catalyst and a hydrogen peroxide stabilizer.  Cyclohexane is oxidized in situ by this reaction. The catalysts are as described in Specifications 1,041,045 and 1,056,125.ALSO:H2O2 is prepared by contacting H2 and O2\t in a liquid medium in the presence of a solid catalyst, water and an H2O2 stabilizer.  The stabilizer may be polymeric containing two or more acid phosphate groupings, e.g. salts of acid phosphate esters of polyhydric alcohols, salts of polyphosphoric acids or condensed phosphoric acids having a polymerization number of up to about 14 in amount 20-200 p.p.m. Other stabilizers may be aluminates, silicates, titanates, stannates, antimonates, thymol, acetanilide, phenacetin, benzoic acid, glycerol phenyl ether, thio-urea, uric acid, glycol mono - acetate, salicylates, citrates, hydroxyquinolines, carboxypyridines, carboxyquinolines, hexanethylenetetramine, nitriloacetic acids, a -amino-carboxylic acids, gum arabic, gum tragacanth, alumina, gelatine, agar phosphatides, and cation-exchange resins. The stabilizer may be in solution or suspension. In a batch process glass reaction vessels may be rinsed with a solution of the stabilizer before use.  For a continuous process stabilizer is added to the reaction mixture. The liquid reaction medium may be an inorganic acid solution and a second acid radical, e.g. sulphate, nitrate, fluoride, chloride, bromide, cyanide, cyanate, thiocyanate and phosphate may be present.  One or more oxygen-containing organic compounds, preferably water-miscible, e.g. an alcohol, aldehyde, ketone, ether, ester, amide, oxygen-containing amine or carboxylic acid may be present preferably in amount such as to form a single liquid phase.  The solid catalysts are at least one element from Groups 1 or 8 as described in Specification 1,041,045 or a palladium salt of an isopoly or heteropoly acid as in Specification 1,056,125. The process may be carried out at atmospheric pressure or at up to 50 atmospheres each of H2 and O2. An unreactive diluent gas may be present and air may therefore be the source of oxygen. 20 DEG  C. is a convenient temperature, but a higher concentration of H2O2 is obtained at 0 DEG  to - 20 DEG  C. or below.

Title: Methods of separating materials of different specific gravity
IPC: B03B5/30
Filed: 1946-10-01
Abstract: In a heavy media sink and float separation process in which the solid phase of the medium is a finely divided magnetizable solid, the material to be treated is introduced into the upper layers of the separatory fluid in a vessel in which an adjustable upward current is produced to remove floating particles, an intermediate fraction is withdrawn from below the overflow but sufficiently high to ensure freedom from high gravity particles and a heavy fraction obtained from the bottom of the vessel, as described in the parent Specification, but in which the small sizes -0.1 to -0.15 inch fraction need not be concentrated and may be partly removed with slimes by classification; both heavy and intermediate fractions are drained and washed to give intermediate and heavy concentrates, the drainings, washings and fines fraction, preferably after the removal of non-magnetizable solids, being subjected to a magnetic separation to remove magnetizable solids which, after demagnetizing, are reused in the separatory fluid.  The raw feed may be crushed, hydraulically classified and treated in a separatory cone to produce light fines, intermediate and heavy fractions.  The light fines with washings and drainings from the screening of the intermediate and heavy fractions are collected and treated in a magnetic thickener-separator, the clean magnetic particles, after demagnetization, being returned to the system, the non-magnetic particles and water being discarded.
