A benzalkonium chloride (BKC) catalyzed oxidation of pentaammine cobalt(III) complexes of both bound and unbound α-hydroxy acids by tributylammonium chlorochromate (TriBACC) has been studied. Perchloric acid is adapted as a medium and the oxidative kinetics was contrived spectrophotometrically at room temperature. Rate of TriBACC oxidation is carried out at pseudo-first order conditions and rate constant was calculated. Absence of salt effect is observed on increasing NaClO4 concentration. Abatement in UV-visible absorbance at 503 nm for Co(III) complex confirms to nearly 100 % of initial absorbance. The complex2+ shows inner sphere mechanism and induced electron transfer reaction yields 100 % Co(II). The product formed in this oxidation was analyzed and polymerization test was carried out. Comparative study of rate of TriBACC oxidation in presence of benzalkonium chloride is listed out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
