A Promoting Effect of Phosphorus-Addition to Cu/SiO2 on Selective Synthesis of Formaldehyde by Dehydrogenation of Methanol

Article abstract of DOI:10.1246/cl.1988.273

Copper supported on SiO2, which was prepared from Cu(OCOCH3)3 and to which P was added, was a selective catalyst (80-85 percent at about 50 percent conversion) for the formation of HCHO by the dehydrogenation of CH3OH at 500 deg C.Among various additives such as P, B, K, Li, Mo, and Zn, the addition of P to the Cu/SiO2 significantly enhanced the rate for the formation of HCHO with an increase in the selectivity.
