Abstract
A method for purifying organosilicon precursor compounds is provided. It includes preparation of the adsorbent with a treating compound. The thus-treated adsorbents can be used to remove impurities such as organic impurities and moisture from a composition containing an organosilicon containing compound. In this manner, it is able to purify organosilicon precursors (or solutions containing organosilicon precursors) without inducing decomposition of the organosilicon precursor.
