Procedure

A solution of 81 gm (1.5 mol) of sodium methylate in methanol, prepared by reacting 34.0 gm (1.5 mol) of sodium with 500 ml methanol, was mixed with 27.0 gm (1.5 mol) of water and subsequently with 1000 gm (6.6 mols) of tetramethoxy-silane. The mixture was heated for about 15 minutes under reflux. Then methanol and excess tetramethoxy-silane were distilled off under water jet-vacuum. 231.5 gm of sodium trimethoxy-silanolate were obtained. Theoretically 240.3 gm (1.5 mol) of this compound should have been formed.
