General description
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.
Application
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.
