Abstract: An apparatus for the in situ NMR studies of intermediates on the homogeneous catalysis and synthesis of organophosphines is described. Using this technique, the hydroformylation of 1-hexene with rhodiumphosphine complex Rh(acac) (CO) (PPh3)under the industrial reaction conditions (H2/CO=1:1,1.5 MPa; 75~80℃) was studied.At same time, under the following reaction conditions:temperature 70~75℃, pressure 2.0MPa, solvent C6D6 and initiator AIBN, the reactions of PH3 with olefins containing N atoms were also studied.
