実験手順

0.5 g of an 0.5% strength palladium/aluminum oxide catalyst is added to 154 g (1 mole) of 3,6-dimethyl-oct-1-yn-3-ol and hydrogenation is carried out at 20°-50° C. and 0.5 bar hydrogen pressure. When hydrogen absorption has ceased (after 6-8 hours), the catalyst is filtered off and the filtrate is fractionated. 145 g of main fraction, boiling at 42°-43° C./0.01 mbar, are obtained; nD25 =1.4345. This corresponds to a yield of 91%. Scent: fresh, floral, lavender-like.
