ResumoThe hydrolysis of acetyl chloride in mixed solvent of acetone-water was investigated by means of an electrical conductance method. The temperature was varied over the range of −35°C to +10°C, and the solvent composition was varied over the range of 10 to 25% of water by volume. The reaction was found to be first order with respect to water and first order with respect to acetyl chloride over the range investigated. A strong dielectric constant influence was found, manifesting itself in an influence on the isodielectric entropy of activation. This effect was consistent with electrostatic theory and followed the dipole-dipole type of dielectric constant dependence. The dipole moment of the activated complex was estimated to be 16 debyes.
