Abstract
Alkenylalkoxysilanes such as allyltrimethoxysilane can be made by reacting the corresponding monoalkenyldichlorosilane, i.e., allyldichlorosilane, with a monohydroxy alcohols, i.e., methyl alcohol. No catalyst is required and the reactions can be carried out at room temperature.
Claims5
A method of making an organofunctional silane comprising reacting a monoalkenyldichlorosilane with a monohydroxy alcohol having 1-6 carbon atoms to form an alkenylalkoxysilane, and separating the alkenylalkoxysilane from the reaction mixture.
A method of making allyltrimethoxysilane comprising reacting allyldichlorosilane with methyl alcohol without a catalyst at room temperature and separating allyltrimethoxysilane from the reaction mixture.
