Abstract
A process for the removal of contaminating residues of a homogeneous catalyst comprising a hydrocarbon soluble compound of a transition metal from Group VIII of the Periodic Table and a metal alkyl or alkyl halide cocatalyst from a liquid hydrocarbon reaction product comprises treating the contaminated product with an aqueous solution of a silicate, borate or carbonate and separating and recovering the hydrocarbon phase. Residues of oligomerization catalysts, polymerization catalysts and hydrogenation catalysts are removable by this process, especially nickel, cobalt, iron, aluminium and halogen residues.
