Technology Process of Phosphorus oxide

There total 6 articles about Phosphorus oxide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 35.0%

oxygen (80937-33-3) + arsenic(III) trioxide + phosphorus trichloride (7719-12-2,52843-90-0) → phosphorus(III) oxide (12440-00-5) + tetraphosphorus octaoxide (70983-17-4) + arsenic trichloride (7784-34-1)

Guidance literature:

In neat (no solvent); As2O3 added into large excess of PCl3 under N2, heated at 50-60°C with vigorous stirring for 7 h / slight amts. of O2 contained in app.; ppt. sepd., washed with PCl3, soln. distd. (667 Pa, 40°C); NMR anal.;

Reference yield:

phosphoryl nitride → phosphorus(III) oxide (12440-00-5) + ammonia (7664-41-7) + phosphan (7803-51-2) + phosphorus pentoxide

Guidance literature:

With hydrogen; In neat (no solvent); heating in an atmosphere of H2; formation of NH3, P2O5 and P4O6 vapors, PH3 and a red compound (P-oxide);;

Reference yield:
