Abstract
Cetyl trimethyl ammonium bromide (CTAB) assisted Oxidation of hypoxanthine (HXAN), and xanthine (XAN) alkaloids by Mn(VII) occurred smoothly in presence of aqueous Bronsted acid (HClO4, H2SO4) media. The rate of oxidation of HXAN, XAN by Mn(VII) was enhanced due to an increase in [HClO4] / [H2SO4] in the presence of CTAB at a constant temperature. Reaction kinetics obeyed I-order in [Mn(VII)], [HXAN], or [XAN] at constant temperature and acid concentration in micellar (CTAB) conditions. In this present work, the acidity functions developed by Zucker-Hammett, Bunnett, and Bunnett-Olsen were used for analyzing rate enhancement, and the probable reaction mechanism that involves water moiety in the slow step has been proposed according to the criteria of Bunnett-Olsen.
期刊介绍:
RASĀYAN Journal of Chemistry [RJC] signifies a confluence of diverse streams of chemistry to stir up the cerebral powers of its contributors and readers. By introducing the journal by this name, we humbly intent to provide an open platform to all researchers, academicians and readers to showcase their ideas and research findings among the people of their own fraternity and to share their vast repository of knowledge and information. The journal seeks to embody the spirit of enquiry and innovation to augment the richness of existing chemistry literature and theories. We also aim towards making this journal an unparalleled reservoir of information and in process aspire to inculcate and expand the research aptitude.
