  Transetherification of Organosilicon Amines with Cellosolve and Trimethylsilanol

  摘要：

  Kinetics of transetherification of (3-aminopropyl)trimethoxysilane, [3-N-(2-aminoethyl)aminopropyl]trimethoxysilane and (3-aminopropyl)triethoxysilana with Cellosolve and trimethylsilanol were studied. The example of [3-N-(2-aminoethyl)aminopropyl]trimethoxysilane was used to show that the activation energies of the direct and reverse reactions are equal to each other both in the first and in the second stages, which points to independence of the equilibrium constant on temperature (DeltaHapproximate to0). With methoxysilanes, the rate constant of the reverse reaction in the second stage of the transetherification with Cellosolve is higher than that of the direct reaction.
