Zusammenfassung

Das Verhalten des Hydrazins und seiner Derivate gegenüber verschiedenen Oxydationsmitteln wurde untersucht. Die Bedingungen zur raschen Mikrobestimmung des Hydrazins, seiner mono- und disubstituierten organischen Derivate mit 0,02-n Bromatlösung sowie der monosubstituierten Hydrazinderivate mit 0,02-n Jodlösung in alkalischem Milieu werden angegeben.

Summary

A study was made of the behavior of hydrazine and its derivatives toward various oxidants. The conditions are stated for the rapid microdetermination of hydrazine and of its mono- and disubstituted organic derivatives with 0.02N bromate solution and also of the monosubstituted hydrazine derivatives with 0.02N iodine solution in alkaline surroundings.

Résumé

On étudie le comportement de l'hydrazine et de ses dérivés vis-à-vis de plusieurs agents oxydants. On communique les conditions d'un microdosage rapide de l'hydrazine et de ses dérivés organiques mono et disubstitués par une solution de bromate 0,02N, ainsi que de ses dérivés monosubstitués par une solution d'iode 0,02N en milieu alcalin.

Riassunto

E' stato studiato il comportamento delle idrazine con reattivi ossidanti come: bromato e iodato di potassio, cloruro di bromo, acido iodico e iodio in soluzione alcalina.

Sono state definite le condizioni per la microdeterminazione volumetrica rapida della funzione idrazinica nelle idrazine aromatiche sia mono- che bi-sostituite con soluzione di bromato di potassio 0,02-n e di quelle monosostituite con soluzione di iodio in ambiente alcalino.
