抄録

Higher order clustering reactions of Cl− with H2O and ROH for ROH=CH3OH, C2H5OH, and n-C3H7OH were measured in the gas phase with the pulsed electron-beam mass spectrometer. The general trend is found that the obtained −ΔHn−1,n° and −ΔSn−1,n° increase in the order H2O<CH3OH<C2H5OH<n-C3H7OH. This order is just the opposite to the free energies of solvation of Cl−. This is due to the increasingly more unfavorable entropy changes for the solvation of Cl− in the order H2O<CH3OH<C2H5OH<n-C3H7OH. This is clearly manifested on the increasing entropy changes −ΔSn−1,n° for the measured gas-phase clustering reactions for higher alcohols.
