  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.

  Based on commercially available aminopropyltrialkoxysilanes, new monosodium salts of organoalkoxysilanes (sodiumoxoaminopropyldialkoxysilanes) with two types of chemically independent functional -ONa and -OAlk groups at the silicon atom were synthesized and characterized. The sodiumoxoaminopropyldialkoxysilanes obtained can be regarded as AB(2)-type monomers - promising reagents for providing controlled polycondensation and production of functional organosilicon polymers with controlled molecular architectures. Subsequently, polyaminopropylsiloxanes with hyperbranched molecular architectures were obtained by heterofunctional polycondensation of the corresponding AB(2)-type monosodiumoxoorganodialkoxysilanes. The structures synthesized were characterized using Si-29 NMR, H-1 NMR, GPC and elemental analyses. The hyperbranched polymer matrices obtained containing aminopropyl organic radicals showed the ability to stabilize silver nanoparticles. (C) 2017 Elsevier B.V. All rights reserved.
