Abstract

Procedure for the preparation of N-acyl-1-amino-alkane-1,1-diphosphonic acids of the formula **(See formula)** where R, R'and R''= H or lower alcohol, R1 - R4 signify H or alkali metal, characterized in that 1-aminoalkane-1,1-diphosphonic acids are transformed with alkali metal lye into the metal salts alkali, and then the alkali metal salts are further reacted. with an acylating agent.
