Abstract
The 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.
