Abstract:
The goal of this research is to demonstrate the possibility of using a modern in situ spectroscopic method (UV-vis spectroscopy) to investigate the reaction kinetics between 4-nitrobenzaldehyde, malononitrile and dimedone in a mixture of ethanol and water as solvents in the presence of caffeine as a biodegradable Catalyst. A mechanistic insight into the synthesis of a derivative of 4H-tetrahydrobenzo[b]pyrans included spectral kinetics approaches is revealed. specific limiting conditions. To study the influence of various parameters (temperature, solvent, concentration) on the degradation efficiency and to discuss whether describing the reaction by the means of the pseudo-first order kinetic model is convenient. The calculation of kinetic parameters would be an integral part of the report. The first step of the proposed mechanism is recognized as a rate-determining step (k1) and this is confirmed based upon the steady state approximation
