abstract |
1505652 Oligomerizing ethylene IMPERIAL CHEMICAL INDUSTRIES Ltd 23 May 1975 [6 June 1974] 25094/74 Heading C5E Ethylene is oligomerized by contact with a Group VIII metal compound supported on an inorganic particulate material having a hydroxylic surface (defined) substantially free from adsorbed moisture, the compound having two hydrocarbyl or substituted hydrocarbyl groups bonded to the metal, one of said groups being capable of reacting with the hydroxylic surface of the support provided that both of said hydrocarbyl groups are not #- bonded to the metal and the total number of centres involved in the #-bonding does not exceed 6. Suitable inorganic supports are y alumina, silica, aluminium phosphate and zirconium phosphate. Preferred catalysts are compounds of nickel containing one #-bonded group (#-allyl or #-crotyl) and one #-bonded group (methyl or benzyl), and optionally a group acting as a Lewis base (e.g. PR 3 ). |
