Kinetic study of a complex triangular reaction system in alkaline aqueous-ethanol medium using on-line transmission FTIR spectroscopy and BTEM analysis

► Kinetics of complex triangular organic reaction in aqueous-ethanol media is studied. ► On-line reaction monitoring carried out using transmission FTIR spectroscopy. ► BTEM analysis provides pure spectra of reactive species and their concentrations. ► Effects of solvent and temperature on the reaction kinetics are investigated. ► Dominant synthetic pathway in the triangular system changes with ethanol:water ratio.
