Abstract: | In the 3-aminopropyltriethoxy silane–deuterated ethanol–H2O system, the rate of release of ethanol from the ethoxy groups, a reaction which occurs during the condensation process, has been followed by use of 1H NMR spectroscopy at different temperatures. Two separate reaction processes have been identified, and values of the reaction rate constants and thermodynamic parameters (Ea, ΔH‡ and ΔS‡) have been calculated. |
