Zusammenfassung:1. A process for the production of 3-amino-1-hydroxypropane-1,1-diphosphonic acid by reaction of beta-alanine with an oxyacid of phosphorus and a phosphorus halide, characterized in that beta-alanine is reacted with a mixture of phosphorus trichloride and anhydrous phosphoric acid at temperatures of from 80 to 130 degrees C and the reaction product is subsequently hydrolyzed.
