Disproportionation of triethoxysilane over KF/Al2O3 and heat-treated hydrotalcite Original Research Article

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 preponderatly 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.
