A process for the preparation of N-derivatives of aminomethane sulfonic acid is carried out by bubbling sulfur (IV) oxide through aqueous solution of hexahydrotriazine N-derivative with essentially quantitative yield of AMSA N-derivative, this is formed by interaction of aqueous solutions of amine and formaldehyde used as raw material.
