Abstract

Un procedimento per la produzione, su scala industriale, di acidi aminodifosfonici secondo la formula (FORMULA) in cui N è compreso tra 2 e 8, a partire da acidi aminocarbossilici, trialogenuri di fosforo e acido fosforoso, con o senza solvente, usando un eccesso di acido fosforoso (rapporti molari dei reagenti compresi tra 1:3:2 e 1:20:6). Il procedimento può essere applicato agevolmente su larga scala e da rese migliori del prodotto, che può essere ottenuto sotto forma di sale direttamente dall'ambiente di reazione senza isolare l'acido corrispondente.
