ABSTRACT:
Tetraethoxysilane is purified by passing impure material through a gas chromatographic separating column at a temperature below the boiling point of the pure tetraethoxysilane. Separation of pure material from impurities occurs on the column, and the pure material is thereafter cooled and collected in a receiver. The purified tetraethoxysilane has 99.999999% purity based on metals content.
