Zur maßanalytischen Bestimmung des Hydroxylamins und Hydrazins

__ LA DfiTERMINATION DU SULFATE D'HYDRAZINE PAR L'HYPOBROMITE A. CAMPE, J. PIJCK et A. CLAEYSLes conditions optimales pour la determination du sulfate d'hydrazine par l'hypobromite de soude en milieu alcalin ont Bt6 determinkes. En employant la mkthode de standardisation dite <(en milieu identiquen le nombre d'klectrons &hang& (n = 2) correspond it la rkaction stochiometrique. La prhision moyenne de la methode, contr616e par comparaison au titrage direct avec le KBrOa-indigo, est de l'ordre de 0,2%. S AMENVA-ITINODe optimale voorwaarden voor de dosage van hydrazinesulfaat met behulp van alcalische hypobromietoplossingen werden bepaald. Het aantal uitgewisselde elektronen (n = 2), bepaald door de methode in analoog milieu, stemt overeen met een stochiometrische reaktie. Precisie en reproduceerbaarheid, gecontroleerd door rechtstreekse titratie van hydrazinesulfaat met KBr03 op indigo indikator, zijn van de grootte-orde van 0,2%.Optimal conditions were determined for the determination of hydrazine sulphate with alcaline hypobromite solutions. The number of electrons exchanged (n = 2), as obtained from standardisations under so-called analogue conditions, corresponds to a stochiometric reaction. Precision and reproductibility, controled by direct titration with KBrOs-indigo, are about 0.2%.

Pure diimine can be easily obtained by the thermolysis of alkalimetal tosylhydrazides Tos(M)NzHz (Tos = p-CH3C6H4S02; M = Li, Na, K) in high vacuum. Diimine is deposited as brilliant yellow solid on a finger cooled at -196°C. On the basis of infra-red spectroscopic investigations it has been found to be trans-configurated. The diimine thermolysis starts at -180°C and leads mainly to nitrogen and hydrazine (disproportionation of diimine), but also to some extend to nitrogen and hydrogen (decomposition of diimine), ammonium azide (dimerization of diimine), as well as nitrogen and ammonia (cleavage of diimine).
