| titleOfInvention | Process for production of trialkylphosphine |
| abstract | A production process of a trialkylphosphine of the general formula (3) according to the present invention includes: a first step of forming a trialkylphosphine of the general formula (3) by reaction of an organic metal compound of the general formula (1) and an organic phosphorous compound of the general formula (2) in an ether solvent having a difference in boiling point with the trialkylphosphine formed such that the difference in boiling point is in a range of 0°C to 20°C; a second step of forming a silver complex of the general formula (4) by absorption of a gas phase containing the trialkylphosphine of the general formula (3) formed in the first step into an aqueous solution of AgI and KI, and then, obtaining the silver complex of the general formula (4) by filtration; a third step of generating a gas product by heating the silver complex of the general formula (4) obtained in the second step, in a metallic reaction vessel, at a temperature range of 170°C to 350°C in a reduced pressure atmosphere of 1.333×10 -7 MPa to 6.133×10 -2 MPa; and a fourth step of cooling the gas product of the third step at a very low temperature range of -196°C to -50°C to thereby trap the trialkylphosphine of the general formula (3) out of the gas product. |
