<p>1,174,927. Hydrodimerisation apparatus. IMPERIAL CHEMICAL INDUSTRIES OF AUSTRALIA and NEW ZEALAND Ltd. 9 Dec., 1966 [15 Dec., 1965], No. 14503/69. Divided out of 1,174,925. Heading B1X. A liquid alkali metal or alkaline earth metal amalgam is reacted with a liquid aqueous organic phase comprising water and a monomer selected fromα, # mono-olefinically unsaturated nitriles and esters to produce the corresponding hydrodimer in apparatus comprising reaction vessel 4, distributor plate 3 (which may be vertically adjustable) supporting a fluidised bed of amalgam, the bed containing between 65% and 20% v/v of amalgam, phase disengagement space 8 above the bed, means comprising pipe 2 for feeding amalgam into the bed above plate 3, means 5 for feeding liquid aqueous organic phase into the vessel below plate 3, and means for removing spent amalgam and the liquid aqueous organic phase containing the hydrodimer from space 8, for example weir 9 over which spent mercury falls, and/or liquid cyclone 12, from which the aqueous organic phase is removed at 14 and the mercury returns through line 13 to the amalgamator.</p> |
