The Effect of Alcohols on the Carbonic Acid Dehydration Reaction.

摘要

The carbonic acid dehydration kinetics have been studied by the stopped-flow technique in CH2OH/H2O and t-BuOH/H2O mixtures. Precise values of the activation parameters of free energy,enthalpy,and entropy have been obtained. The chemical interactions of Mg(+2) with carbonate and bicarbonate in the presence of the Na(+) ion have been studied as a function of temperature and of ionic strength. In the case of MgCO3ion pair formation, a constant enthalpy of reaction was observed in the temperature range investigated. The calculations were based on the EMF measurements using the glass and the ion-selective electrodes.
