A method of making hydroxymethylphosphonate comprising heating paraformaldehyde in a solvent to a desired reaction temperature, wherein the solvent is present in at least an amount necessary to solvate or suspend the paraformaldehyde; adding at least one alkyl phosphite to the heated paraformaldehyde, to provide hydroxymethylphosphonate, the alkyl phosphite being added to the heated paraformaldehyde at a rate which will avoid or inhibit the production of a significant exotherm and resulting high/significant level of acid by-product(s), there being present in the reaction medium at least one hindered amine catalyst in which the nitrogen in the amine is directly bound to a secondary and/or tertiary carbon of an organic group; and, optionally, following the completion of the addition, heating the reaction mixture to an elevated temperature.
