Abstract
Tetraalkyl silicates are produced by the reaction of silicon metal with an alkanol in the presence of an alkali metal salt of an alkoxyalkoxy alcohol or a polyalkylene glycol in either an alkoxyalkoxy alcohol or a polyalkylene glycol or mixtures thereof and recovery of the product. Tetramethyl silicate and tetraethyl silicate are the preferred products. The preferred alkoxyalkoxy alcohol is 2-(2-butoxyethoxy)ethanol. The preferred glycol is diethylene glycol. An indifferent solvent and/or a hydroxide-scavenger may be employed in the reaction mixture.
