Abstract

Abstract : Starting from silicon dioxide or silicon a scalable, reliable synthesis of 29 Si enriched tetraethoxysilane, an essential sol–gel precursor, is presented. Abstract : 29 Si enrichment would be advantageous for many NMR studies of the structural properties of sol–gel derived materials. The required starting materials ( 29 Si enriched alkoxysilanes), however, are expensive and difficult to provide. Here we present a scalable, reliable synthesis of 29 Si enriched tetraethoxysilane starting from silicon dioxide or elemental silicon with a total yield up to 75%.
