Procedure

Using the procedure described in Example 1, 29.0 parts (0.5 mole) of finely divided magnesium hydroxide and 500 milliliters of dimethyl methylphosphonate are heated at reflux for 4 hours. The solid product is collected, washed with acetone and dried at 100° C. under vacuum to constant weight. There are obtained 62.6 parts of monomethyl methylphosphonic acid magnesium salt melting >230° C. and having micro analysis % Mg, 9.36; % P, 23.70; Calculated for C4H12O6P2Mg.H2O: % Mg, 9.23; % P, 23.85.
