Beschreibung

Allgemeine Beschreibung

Silicon tetraacetate is an alternative to silicon hydride and alkoxide for low-temperature SiO₂ production. Silicon tetraacetate reacts with ethanol in absence of water to form silica gel and ethyl acetate. Silicon tetraacetate is reported as a sol-gel precursor.

Anwendung

Silicon tetraacetate may be used in the preparation of silicon dioxide thin films by a direct photochemical vapor deposition method. It may be used as starting material in the synthesis of silicon complexes with monofunctional bidentate Schiff bases.
