The kinetics of self-association of ethanol in ethyl chloride
Ultrasonic absorption data in ethanol—ethyl chloride solutions reported by Solovyev et al. have been re-examined using a reaction scheme based on ethanol self-association monomer ⇌ dimer ⇌ trimer It is concluded that the excess absorption observed is due primarily to the monomer—dimer process which is assumed to be the faster step. The concentration of trimer formed is small below 0.2 mole fraction ethanol but increases rapidly above this point. The self-association of ethanol in this system is confirmed qualitatively by a PMR study.
