A cycloalkyl phosphorus compound is obtained by the catalytic hydrogenation of a substituted or unsubstituted aryl phosphonic acid using a heterogeneous catalyst which is a Group VIII metal on carbon. The hydrogenation is preferably effected in water. The catalyst can be ruthenium or carbon. When phenylphosphonic acid is used as the starting material, a yield of about 95% of essentially pure cyclohexylphosphonic acid can be obtained.
