Abstract

Transetherification of organylalkoxysilanes with monoethanolamine was carried out. Disproportionation in mixtures containing organylalkoxysilanes with an amino group in the substituent was studied by means of NMR spectroscopy. It was shown that the disproportionation rate decreases with increase size of substituents on the silicon atom. The equilibrium composition of disproportionation products corresponds to the normal statistical distribution, except for mixtures containing tris(1-methylpropylideneaminooxy)(vinyl)-silane.
