The synthesis of polyorganosiloxanes from mineral silicates was formulated originally to investigate the structure of the silicates,|1-3~ as the poor crystallinity of some mineral samples precluded structural determination by X-ray methods. A useful method for determining the silicate anions present in mineral silicates is by trimethylsilylation, and the subsequent study of the polyorganosiloxane derivatives by chromatographic techniques.

The trimethylsilylation reaction can...
