An improved process for preparing 2,4,6-tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes is realized when the appropriate substituted-phenylphosphorodichloridite is reacted with water in the presence of a trialkyl amine wherein the alkyl groups contain 4 to 8 carbon atoms in acetone as the sole solvent, to provide the desired 2,4,6-tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes in increased yields and of a higher purity.
