Abstract: 1339183 Metallic chloride separation GULLSPANGS ELEKTROKEMISKA AB 8 Oct 1971 [8 Oct 1970] 46888/71 Heading C1A Metallic chlorides are separated from aqueous solution in at least two stages using an immiscible amine solution, the chloride concentration being less than 150 g/l in the 1st stage and being increased between stages to separate different chlorides. As shown in Fig. 2, an alloy of Fe, Co and Ni is added to the anodic sections of cells 2, 4 and 6. The metallic chloride solutions produced are combined and Fe<SP>2+</SP> ions are converted to Fe<SP>3+</SP> in the anodic chamber 7. The solution is filtered at 9 and contacted with amine solution at 10. Ferric chloride is washed out of the extract phase at 11, the solvent being returned to 10. Fe<SP>3+</SP> is reduced to Fe<SP>2+</SP> in cathodic chamber 8 before reaching cathodic chamber 5 where Fe deposits. The raffinate from 10 passes to evaporator 12 where it is concentrated, the condensate being used for washing out the chlorides and diluting the final extract. Co is separated in 13 and 14 and is deposited in 3, the remaining Ni being deposited in 1. The process is useful for recovering metals from scrap alloys.

Patent GB-981707-A (GB)
Title: Recovery of oxidation products
IPC: C07C37/08
Filed: 1963-12-11
Abstract: Dihydroperoxides are made by oxidation of dialkyl aromatic hydrocarbons of the formula <FORM:0981707/C2/1> wherein Ar is an arylene group and R1, R2, R3 and R4 are alkyl groups, by contacting the dialkyl aromatic hydrocarbon with molecular oxygen, subjecting the oxidate which contains the monohydroperoxide and dihydroperoxide of the dialkyl aromatic hydrocarbon to extraction with an aqueous solution of an alkali metal hydroxide to remove the dihydroperoxide, treating the resultant organic phase which is substantially free from dihydroperoxide with gaseous carbon dioxide, washing the so treated organic phase with water, and recycling the washed organic phase to the oxidation stage. Preferred hydrocarbons are m- and p-diisopropylbenzenes. The oxidation is preferably effected at a pH within the range from 3 to 7 using molecular oxygen either alone or diluted with nitrogen at temperatures in the range from 50 DEG  to 150 DEG  C.  The alkali may be sodium hydroxide or potassium hydroxide preferable in an aqueous solu containing 1 to 12% by weight of alkali metal hydroxide.  The treatment of the organic phase with carbon dioxide may be carried out at temperatures ranging from 15 DEG to 80 DEG  C. at least sufficient CO2 being employed to neutralize the alkali content. The gas may be introduced through suitable distribution apparatus and preferably the organic phase and carbon dioxide are passed in countercurrent flow through a packed column. The treated organic phase is washed with water to remove salts, the washing being effected after, or simultaneously with, the CO2 treatment.  Thus the water may be fed in with the organic phase at the top of a scrubbing column wherein CO2 passes in countercurrent flow. The separation of the phases after the alkali extraction, and the separation of the aqueous salt solution from the organic phase after washing, may be effected by centrifuging. Detailed examples are given and the effect of neutralizing the organic phase with CO2 is compared with neutralization using sodium sulphate containing sulphuric acid or buffered sodium phosphate solution.

A adjustable-pitch aerofoil stator vane unit for a turbine or compressor comprises a stator vane 24, Fig. 2; a platform 60, Figs. 2 and 4, having at least one circular portion, a platform 30, Figs. 2 and 3, at the other end of the vane having a circular portion 32; a housing 68 having an opening at least partly circular in shape to recive the platform 60; a seal ring 88 between the housing 68 and the platform 60; a housing 38 having a circular recess 36 to receive the circular portion 32 of the platform 30; a journal 42 extending from the platform 30 and journalled in a bearing 44 having a spherical surface to allow relative tilting between the bearing housing 48 and the vane 24; and actuating means 110 connected to the platform 60 for adjusting the vane. A small clearance between each platform and its neighbour permits the adjustment. In the embodiment shown, the vane 24 is a turbine stator vane in a gas turbine engine, and coolant, which may be compressor discharge air, enters a pivot bearing 82 via a passage 92 and flows through an annular chamber 100 between a bearing bush 82 and the outer pivot spindle 86 of the vane and thence through a passage 103 and an annular chamber 104 to enter the hollow interior the the vane. The coolant then flows out of the vane through the hollow journal 42 to an annular chamber 54 and thence via a passage 56 and a chamber 58 to join the combustion gases. Since the coolant is at a higher pressure than the combustion gases, its presence in the chamber 58 minimizes leakage of combustion gases between the platform 30 and the recess 36. Seal ring 88 is urged into sealing contact with the platform 60 and the housing 68 by coolant pressure communicated via a passage 114, a chamber 116 and a gap 118.
