Abstract 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, ...
