Abstract

Pyrophosphoryl chloride, P2O3Cl4, is prepared by reacting POCl3 and P2O5 in a sealed vessel at 150-250, preferably 200 DEG C., and distilling off the P2O3Cl4 at a reduced pressure of 12 mm. Hg. from the resulting mixture of condensed phosphoryl chlorides, after the POCl3 has first been distilled off. The molar ratio of POCl3:P2O5 is 3:1 to 5:1 and trimetaphosphoryl chloride, P3O6Cl3, is also present in the product. The P2O3Cl4 may be redistilled and may be crystallized by cooling to -30 DEG C.
