ABSTRACT:
An improved process for preparing alkali metal siliconates wherein the improvement comprises, first substituting at least 20-90 mole percent of the chlorine groups on the silanes with hydrocarbonoxy groups, by reacting the chlorosilane with an aliphatic alcohol or alcohol and water heating the mixture to remove acid and then finally adding the alkoxylated silane to an aqueous alkali metal hydroxide solution to form the desired alkali metal siliconate.
