        Ketone produced during the dehydrogenation of secondary alcohols has a strong inhibitory action on the further reaction.  It has a markedly higher adsorption coefficient than the alcohol.  The factors influencing the ratio of the adsorption coefficients of the ketone and alcohol are examined:  for example, the temperature, the solvent, and the catalyst.  2-Propanol and 2-butanol are dehydrogenated under various conditions.  The temperature increased the rate of reaction and changes the ratio in favor of the alcohol.  No obvious influence of the solvent on the ratio has been observed.  Different samples of Ni and Cu are used as catalysts.  Cu is less active than Ni, but it changes the ratio slightly in favor of the alcohol.
