Investigation of the hydrogenation of acetophenone by a kinetic isotopic method

Conclusions

  1. 1.

    The stepwise mechanism of the reduction of acetophenone in the presence of Rh and Co catalysts was investigated by the kinetic isotopic method.

  2. 2.

    In the presence of a Rh catalyst, methylcyclohexylcarbinol is formed primarily through the stage of methylphenylcarbinol, and ethylbenzene through the stage of methylphenylcarbinol, as well as directly from acetophenone.

  3. 3.

    In the presence of a skeletal Co catalyst, ethylbenzene is produced primarily through the stage of methylphenylcarbinol.
