Abstract

This reaction is a one-step industrial production of butadiene from ethanol at temperature of 400–450°C in the presence of a catalyst with both dehydration and dehydrogenation processes and is generally known as the Lebedev process. The best catalyst for this process has been reported to be a silica gel impregnated with tantalum oxide (SiO2-Ta2O5), silicamagnesium-tantalum, and silica-magnesium-chromium. Several mechanisms have been proposed for synthesis of butadiene and found the most important evidence for the real mechanism is that conversion of crotonaldehyde and ethanol to butadiene. This process has been used for the production of butadiene for synthetic rubber.
