Abstract:
A new experimental procedure for studying the kinetics and thermodynamics of chemical reactions in supercritical fluids-solvents was suggested. The kinetics and mechanism of the dehydration of 2-propanol in supercritical water in a closed reactor were studied. It was found that, first, the dehydration mechanism significantly differed from that observed in the presence of a homogeneous acid catalyst and, secondly, the rate of the reaction substantially depended on the density of supercritical water. A general mechanism of the dehydration of 2-propanol in supercritical water was suggested based on experimental studies of the hydration and hydrogenation reactions of some desired reaction products. The experimental data were well described by first-order kinetic equations. The kinetics of the reaction was studied and its rate constants determined. The density of supercritical water can be used as a parameter for controlling the kinetics and selectivity of the reaction.
