Reaction Steps
181 g (1 mole) of (3-amino-3-carboxy-propyl)-methane-phosphinic acid are reacted at room temperature with 17 g (1.0 mole) of ammonia (previously dissolved at 0° C. in methanol). The mixture warms up spontaneously to 35° C. and is then refluxed at 65° C. for 30 minutes, cooled, filtered and the crystals are dried to give 193 g of (3-amino-3-carboxy-propyl)-methane-phosphinic acid ammonium salt, which is non-hygroscopic, readily soluble in water, melting at 207°-209° C., containing 90% of (3-amino-3-carboxy-propyl)-methane-phosphinic acid. Yield: 97.5%
