Reaction Steps

A solution of 81.0 gm (1.5 mols) of sodium methylate in methanol, prepared by reacting 34.0 gm (1.5 mols) of sodium with 500 ml of methanol, was first mixed with 27.0 gm (1.5 mols) of water, then with 1000 gm (6.6 mols) of tetramethoxy-silane. The mixture was heated for about 15 minutes under reflux. Methanol and the unreacted tetramethoxy-silane were then distilled off under a water jet vacuum. Instead of the theoretically expected 240.3 gm (1.5 mols) of sodium trimethoxy-silanolate, 231.5 gm of sodium trimethoxy-silanolate were obtained.
