Versuchsvorschrift

The output from the aldolization comprising crude 2-propylheptenal was hydrogenated selectively in the liquid phase over the palladium catalyst H 14535 (0.5% of Pd on aluminium oxide), procured from Degussa, at 160° C. and 2.5 MPa in a circulation apparatus to form 2-propylheptanal. For this purpose, 200 ml/h of starting material were passed continuously over 400 ml of catalyst, corresponding to a space velocity over the catalyst of 0.5 h−1.

Aufarbeitung

  1. customprocured from Degussa, at 160° C.
