Versuchsvorschrift
A mixture of 4,6,6-trimethyl-1,3-cyclohexadiene-1-carbaldehyde (141 g, 0.94 mole), ethanol (1 l) and palladium on charcoal (10%, 0.5 g) was hydrogenated by shaking under a H2-atmosphere for 3.5 h. The H2-consumption was 23.5 l. After filtration and concentration of the thus-obtained solution, the residue was distilled at 50°/0.7 hPa, to obtain 125.3 g (87.6%) of the desired product.
