| 摘要 |
The invention relates to a method for producing 1-(2,2,6-trimethylcyclohexyl)-3-alkanols having a trans isomer content of at least 15 % in relation to the total quantity of the 1-(2,2,6-trimethylcyclohexyl)-3-alkanol, by means of catalytic hydrogenation. The method involves reacting a) 1-(2,6,6-trimethyl or 2-cyclohexen-1-yl)-1-alken-3-ones in the presence of catalysts or catalyst mixtures containing ruthenium, or b) 1-(2,6,6-trimethyl-1 or 2-cyclohexen-1-yl)-1-alken-3-ols in the presence of catalysts containing at least one element from groups Ib, VIb and VIII of the periodic table. |
