Reaction Conditions:

with trichlorophosphate at -5; for 4 h;Temperature;

Steps:

1 Trihexylphosphine Preparation:
After the reaction solution was cooled to -5 ° C, 42 g of phosphorus trichloride was added dropwise slowly (about 2 hours), and the mixture was stirred for 2 hours. The reaction solution was then depressurized Distillation, in particular, vacuum distillation prior to 0.09 MPa, distilling off toluene and tetrahydrofuran, and then collecting the fraction at 140-142 ° C under high vacuum at 20 Pa to give 267.3 g of trihexylphosphine with a purity of 99.3% The rate was 92.6%
