Discussion Water, methanol, ethanol, dioxane and benzene were used as reaction media and water was found to be the most suitable for the Adams catalyst and satisfactory for the Raney catalyst.

Higher pressures gave increased adsorption rates for the Adams catalyst but were Gthout much effect for the ...
