Spectroscopic investigation on kinetics and mechanistic aspects to electron-transfer process into quinolinium dichromate oxidation of a high blood pressure drug captopril in acidic medium

摘要: Abstract This study investigated on kinetics of oxidation captopril by QDC was studied spectrophotometrically in acidic medium along with its mechanistic pathway. Such studies are greatly helpful gaining an insight into the interaction metal ions through pathway CPL redox reactions. The oxidative product found to be disulfide separated, and identified FT-IR. A suitable free radical mechanism proposed. reaction exhibited first-order respect [oxidant] fractional order CPL. Consequently, between complex species is supported kinetic orders spectrophotometric verification, positive entropy activation rate constant increased increase dielectric ionic strength medium. constants involved were computed overall parameters evaluated which lend support proposed mechanism.
