실험 절차

101 g (0.5 mol) of diphenylphosphine oxide and 0.4 g of zinc chloride are mixed and heated to 164° C., the pressure being reduced simultaneously (14 mbar). Diphenylphosphine distills off through a descending condenser at a transition temperature of 148° C. The internal temperature is finally raised to 183° C. 41 g of diphenylphosphine are obtained. That corresponds to a yield of 88% of theory.
