Versuchsvorschrift

154 g (1 mole) of 3,6-dimethyl-oct-1-yn-3ol are dissolved in 100 ml of methanol, 1 g of an 0.1% strength palladium/calcium carbonate catalyst, which has been poisoned with zinc ions, is added, and hydrogen is passed in at 20° C. under atmospheric pressure. The hydrogenation is complete in 6 hours, when about 24 liters of hydrogen have been absorbed.
