Abstract

The preparation of lubricating oils by the AlCl~2~ polymerisation of the olefines present in the primary product obtained by atmospheric pressure synthesis from carbon monoxide and hydrogen (ratio 1 :2) over a cobalt catalyst has been carried out in 2โ€gallon batches. The effect of varying temperature, catalyst and boiling range of starting material on the reaction and its products is described. The oils obtained possess properties which approximate to the requirements of the Air Ministry Specification D.T.D. 109 for aircraft lubricants in all respects except the increase in viscosity on oxidation. It was found possible to overcome this disability subjecting the oils to a carefully controlled hydrogenation in the presence of molybdenum disulphide.
