Conclusions

  1. 1.

    The hydrogenation of p-carboxybenzaldehyde proceeds according to zero order with respect to the substrate and according to first order with respect to H2.

     
  2. 2.

    On Pd-catalysts, hydrogenation is accompanied by subsequent hydrogenolysis of the C-OH bond of the carbinol formed.

     
  3. 3.

    On a Rh-catalyst hydrogenolysis proceeds extremely slowly, while on a Ru-catalyst p-carboxy-benzyl alcohol is selectively formed.
