Nandibewoor, Auteur Année de publication : 2009 Article en page(s) : pp. 7550–7560 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Guanidine hydrochlorid Diperiodatoargentate(III) Catalyzed oxidation Résumé : The oxidation of guanidine hydrochloride (GH) by diperiodatoargentate(III) (DPA) has been investigated both in the absence and presence of [Os(VIII)] catalyst in alkaline medium at a constant ionic strength of 0.10 mol dm−3 spectrophotometrically. The oxidation products were identified by spectral studies. The stiochiometry was same in both the cases, i.e., [GH]/[DPA] = 1:1. In both the catalyzed and uncatalyzed cases, the order of the reaction with respect to [DPA] was unity while the order with respect to [GH] was En ligne : http://pubs.acs.org/doi/abs/10.1021/ie900691z [article] Mechanistic investigation of uncatalyzed and osmium(VIII) catalyzed oxidation of guanidine by Ag(III) periodate complex in aqueous alkaline medium : a comparative kinetic approach [texte imprimé] / Jyothi C.
