    摘要： Amidosulfonic acids are manufactured by reacting Schiff bases first with sulfur trioxide and then with water. The compounds obtainable by the process of the invention are sweeteners (especially in the case of cyclohexylamidosulfonic acid and its calcium, sodium and potassium salts), and valuable starting materials for the manufacture of sweeteners, dyes and pesticides.
