Abstract

Under fixed-bed flow conditions, silane, diethoxysilane, and tetraethoxysilane are formed by the disproportionation of triethoxysilane over a KF/Al₂O₃ or a heat-treated hydrotalcite catalyst. The reactions at 393 K give preponderantly either silane with 17-21% yields or diethoxysilane with 5-10% yields. The preponderance depends on the contact time and the amount of KF loaded on Al₂O₃.
