Abstract: The present invention relates to a method for separating organohalosilanes. The method includes introducing a mixture including at least a first organohalosilane and a second organohalosilane onto a chromatographic bed including a stationary phase. The method also includes passing a liquid mobile phase through the chromatographic bed to produce an eluate including at least one fraction enriched in the first organohalosilane and at least one fraction enriched in the second organohalosilane.
