Abstract
The present invention relates to a process for preparing 4-cyclohexyl-2-methyl-2-butanol. The process comprises the following steps: a) reaction of styrene with isopropanol at elevated temperature to obtain 4-phenyl-2-methyl-2-butanol, and b) heterogeneously catalyzed hydrogenation of 4-phenyl-2-methyl-2-butanol over a catalyst suitable for ring hydrogenation of aromatics.

A process for preparing 4-cyclohexyl-2-methyl-2-butanol, comprising:
- a) reaction of styrene with isopropanol at elevated temperature to obtain 2-methyl-4-phenyl-2-butanol, and
- b) heterogeneously catalyzed hydrogenation of 2-methyl-4-phenyl-2-butanol over a catalyst suitable for ring hydrogenation of aromatics.
A composition comprising 2-methyl-4-phenyl-2-butanol and 2-methyl-4-phenyl-2-pentanol.
A process for preparing a composition comprising 2-methyl-4-phenyl-2-butanol and 2-methyl-4-phenyl-2-pentanol, which comprises reacting styrene with isopropanol at elevated temperature under conditions under which isopropanol is present under supercritical conditions, the molar ratio of styrene to isopropanol being in the range from 1:10 to 1:130.
