Patent GB-906163-A (GB)
Title: Process for the manufacture of a mixture of olefine oxidation products containing an olefine oxide
Filed: 1960-04-25
Abstract: A mixture of olefine oxidation products containing an olefine oxide is obtained by reacting an olefine-mercury co-ordination compound at elevated temperature with water in an aqueous phase having a pH value equal to or greater than 7.  The preferred temperature range for carrying out the reaction is 100-150 DEG C.  It may be advantageous to add an organic solvent to the reaction mixture, the preferred solvents being glycol and glycerin.  There may be present in the reaction mixture a salt, for example an alkali metal carbonate; an alkali metal phosphate; lithium, sodium, potassium, beryllium, magnesium, aluminium, manganese, iron, nickel, copper, zinc or calcium sulphate; lithium, sodium, potassium, calcium, magnesium or aluminium chloride; sodium thiosulphate, potassium thiocyanate or an organic salt of an alkali metal.  Hydroxides of lithium, sodium, potassium and barium may also be added.  The mercury-olefine compounds used as starting materials may be made by mixing the olefine with a mercury compound.  Preferably they are made by adding an olefine to an aqueous solution or suspension of a mercury salt.  A mixture of olefines may be used and the mercury salt may be inorganic or organic.  Other suitable mercury compounds are, for example, methyl - mercury fluoride, alkyl mercury hydroxides, alkyl- and phenyl-mercury salts, olefine-dimercury chlorides, aliphatic alcohol-mercury salts and ether-mercury salts.  The absorption of the olefine preferably takes place at 0-90 DEG C. using a solvent, for example, water, aqueous salt solutions or aqueous solutions of organic compounds at a pH below 7.  In the manufacture of the olefine oxide the pH value of the mixture is preferably in the range 8-14 at a temperature in the range 70-300 DEG C.  The charge of the mercury salt with the olefine and the production of olefine oxide can be carried out either in two different vessels or in the same vessel. Examples are given of (a) the conversion of an ethylene compound of mercury to a mixture of acetaldehyde and ethylene oxide and (b) the conversion of a propylene compound of mercury to a mixture of propylene oxide and acrolein.

Inventor: CORFA YVES
IPC: G21F7/01
Filed: 1965-04-07
Abstract: 1,063,726. Irradiation apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 7, 1965 [April 7, 1964], No. 14716/65. Heading H5R. Apparatus for moving a radio-active source 1 from a storage position to an irradiation position by pneumatic means, comprises a tubular conduit 2, 18 (Fig. 5) made up of three sections to allow rotation of at least the irradiation end section about the axis of the central section. In the storage position the source is seated in the end of a cylindrical conduit (18, Fig. 3, not shown), fitted with a closure plug (22) and a microswitch (23) which is actuated by the presence of the source on the spring contact (21). The inputs from the compressor and outputs for the pneumatic fluid (air) are located adjacent the central section (11) of the conduit (Figs. 2, 4, not shown). To remove the source 1 from the storage position, air from the compressor is supplied to the annular space between the storage conduit section 18 and its outer jacket (19) through a line 28 and tube 40, driving the source past the highest point of the tube section 18, from where it drops under gravity to the irradiation end 2 of the conduit, where air cushions its fall on to seat (6) also provided with a microswitch (8) &c. To return the source to storage, compressed air is pumped through line 25 into the annular chamber (13) between central conduit section (11) and its outer jacket (12) from where the air travels along a tube (5) to the annular chamber (4) between the irradiation conduit section (2) and its outer jacket (3) to force the the source 1 upwards. The air is vented to the atmosphere, in both cases, through passages (35, 36) and a tube (37) arranged near the central section (11). A number of such tubular conduits may be used in an irradiation plant for cereals such as wheat or maize (Fig. 7, not shown). The conduit members (e.g. 51, 52) are located near the bottom of a hole in a concrete shield. Cereal from a silo (41) is passed into a chamber (46) arranged to produce a downward moving curtain of material for irradiation, the irradiation end sections (53) of the tubular conduits being swivelled round adjacent the chamber by means of a motor drive (55) or transmission systems (57).
