Abstract
A novel route to tetraethoxysilane and other silicon alkoxides is described,
from amorphous silica
(SiO2.nH2O)
as the raw material. The reaction of amorphous silica with triethanolamine is
enhanced by using an alkali metal hydroxide catalyst, to form a range of
triethanolamine-substituted silatrane species. These can undergo alkoxide
exchange in acidic alcohols to form alkoxysilatranes, tetraalkoxysilanes,
hexaalkoxydisiloxanes and higher siloxanes. Reaction of
triethanolamine-substituted silatranes with acetic anhydride produces
acetoxysilatrane. Products were identified by multinuclear
(1H, 13C and
29Si) magnetic resonance spectroscopy, electrospray mass
spectrometry or high-resolution gas chromatography electron impact mass
spectrometry.
