Zusammenfassung:The invention relates to N-amino-1-hydroxy-alkylidene-1,1-bisphosphonic acid derivatives and to a process for their preparation as well as their salts Alkylpyrophosphonates, alkylpyrophosphates and multimers are produced first, finally producing 4-amino-1-hydroxyalkyllidene-1,1-bisphosphonic acids and the salts thereof The acids derivatives produced this way, in genuine state, are used in softening and purifying water and in the preparation of some non-toxic medicine
