Abstract

1. A method for preparing N-carboxyalkyl-1-aminoalkane-1,1-diphosphonic acids and carboxyalkylamino-phenylmethane-diphosphonic acids of the general formula : see diagramm : EP0012194,P6,F1 in which R**1 = H, CH3 , C2 H5 , C6 H5 , c-C6 H11 , HOOC Cm H2m (m = 2-5), CICH2 , C6 H5 -CH2 , R**2 = H, CH3 , C2 H5 , C6 H5 , CH2 COOH, C2 H4 COOH R**3 = H, CH3 , C2 H5 , -CH2 C6 H5 , -C2 H4 SCH3 , -CH2 COOH, -C2 H4 COOH, or see diagramm : EP0012194,P6,F2 or R**1 + R**2 = -Cm H2m CO-(m = 2-5), and n = 1-4 characterised in that acylaminocarboxylic acids or their anhydrides of the general formula see diagramm : EP0012194,P6,F3 in which R**1 , R**2 , R**3 and n have the same signification as above, are made to react with pyrophosphoric acid or phosphoric acid and phosphorus trichloride in the molar ratio of 5:1 to 1:2 at temperatures between 50 degrees and 100 degrees C.
