Hydrogenation of cyclopropane
Webreaction the hydrogenation and hydrogen- olysis of cyclopropane were selected. Sev- eral investigators have studied this reaction on a number of metals, most extensively on … WebWe find that the activation of both C 3 H 8 and c-C 3 H 6 is facile on IrO 2 (110) at low temperature, and that the dissociated alkanes oxidize during TPRS to produce CO, CO 2 and H 2 O above ∼400 K. Propane conversion to propylene is negligible during TPRS for the conditions studied.
