摘要：

Silico-aluminates were synthesized from aluminum and silicon alkoxides by the sol-gel method and characterized by FTIR spectroscopy. The water and alumina concentration effects in specific BET areas and activity in isopropanol dehydration were studied. High specific BET areas were found and a correlation between the tetrahedral coordination and selectivity as well as deactivation is proposed.
