Abstract
Abstract Ultrasonic irradiation was found to acclerate the solvolysis of 2-chloro-2-methylpropane in aqueous ethanol mixtures. The effects were more marked at lower temperatures and higher alcohol compositions, with a 20-fold rate acceleration occurring at 10°C and 60 wt%. The kinetic data were analysed with reference to the variation in solvent structure and vapour pressure. Enthalpies and heat capacities of activation in both the presence and absence of ultrasound were also determined. The result spresented in this Paper confirm the existence of a region of maximum structure in the binary mixture.
