Reaction Conditions

Reaction Steps

A 1-liter autoclave was charged with 5 g of azobisisobutyronitrile, 50 g of benzene and 112 g (1 mol) of 1-octene, and 136 g (4 mols) of hydrogen phosphide was condensed thereinto. The whole was heated to 90° C. The pressure initially rose to 70 bars, then dropped gradually to 55 bars, and remained constant after 5 hours. The reaction mixture was analyzed by NMR-spectroscopy. The octene conversion rate was 85%. Primary octylphosphine was obtained in a yield of 70%, secondary octylphosphine was obtained in a yield of 20%, and tertiary octylphosphine was obtained in a yield at 10%, based on the quantity of 1-octene which underwent conversion.
