HIGH PURITY ORGANOFUNCTIONAL ALKYLDIALKOXYSILANES THROUGH INVERSE ADDITION

摘要

A method is provided for preparing high purity organofunctional alkyldialkoxysilanes by reacting hydroalkyldialkoxysilanes with olefines wherein formation of undesired close-boiling by-products by an alkyl/alkoxy group exchange reaction is minimized through inverse addition, meaning mixing first Silane and Catalyst and then adding the olefin component thereto.
