The decomposition yields of 1,2-bis(diphenylphosphine)ethane (dppe) in cyclohexane and in methanol solutions saturated with Ar or N2O have been determinated from the absorption decrease at 253 nm.The decomposition yields of dppe*HCl dissolved in Ar or N2O saturated methanol have been determined, too.Taking into account the obtained results as well as the variations of the absorption bands and the NMR signals, a radiolysis mechanism has been suggested.Applying the steady state approximation, the reaction rate constants have been calculated : k(e-s+dppe*2HCl)=5.8E8 l mol-1 s-1; k(H+dppe)=2.89E10 l mol-1 s-1; K(CH2OH+dppe)= 1.16*107 l mol-1 s-1.Also the decomposition yield of dppe i the solid phase has been determined and ESR studies have been carried out.
