Catalysts Based on the Immobilized Complexes of Copper with Quaternary Ammonium Bases for Chlorination of Alkanes with Carbon Tetrachloride

摘要

The complexes of copper chloride with quaternary ammonium bases supported on silica are highly active in the reaction of carbon tetrachloride with decane was found in the presence of an electron donor (ethanol). The effectiveness of the catalysts depends on the method of their deposition onto the sup-port.The catalysts obtained as a result of covalent binding with the surface through the formation of siloxane bonds (immobilization) exhibit high stability and higher activity than the analogues prepared by the impreg-nation of the support with the catalytic complex.The introduction of ethanol into the reaction system sub-stantially increases the activity and stability of all of the catalysts.
