Abstract

Hydroxymethylphosphonic acid is prepared by reacting phosphorus trichloride with paraformaldehyde and water, the paraformaldehyde being present in an amount from about a stoichiometric quantity to about a 0.5 mole excess, preferably in the presence of HCl. Alternatively, orthophosphorous acid may be used instead of water and PCl3. The reaction may be carried out under atmospheric pressure in a temperature range between 50 DEG and 150 DEG C. A preferred temperature range is between 90 DEG and 120 DEG C.
