A mixture of 64 g of methane phosphonic acid dimethyl ester (0.516 mol), 352 g of tris-p-cresyl phosphite (1.00 mol) and 2 ml of methyl iodide is slowly heated to 245° C. and tempered at this temperature for 30 minutes. Vacuum distillation yields 376 g of methane phosphonic acid di-p-cresyl ester (Bp1 mm 144° C.), 98.6% pure.
