TRAPPING OF CH3O FORMED FROM CO + H2

Methoxy formed on Al2O3 from (CO)-C-13 and H-2 coadsorption on Ni/Al2O 3 was trapped by C2H5OH adsorption and temperature-programmed reaction (TPR). The presence of excess C2H5OH significantly increases the rate of (CH3OH)-C-13 and ((CH3)2O)-C-13 formation. The (CH3OH)-C-13 forms by the reaction Of C2H5OH with (CH3O)-C-13 on Al2O3. In the absence of C2H5OH, TPR following (CO)-C-13 and H-2 coadsorption did not produce significant amounts of (CH3OH)-C-13 or ((CH3)-C-13)2O.
