Abstract

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, where the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the range from 1:below 5 to 1:0.5.

Claims (7)

1. A process for preparing 2-methyl-4-phenyl-2-butanol, comprising a) the reaction of styrene with isopropanol at elevated temperature, where the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the range from 1:below 5 to 1:0.5.

2. The process as claimed in claim 1 , wherein the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the range from 1:4.9 to 1:0.5.

3. The process as claimed in claim 1 , wherein the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the range from 1:4.5 to 1:0.5.

4. The process as claimed in claim 1 , wherein the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the range from 1:4 to 1:0.75.

5. The process as claimed in claim 1 , wherein the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the range from 1:3.5 to 1:1.15.

6. The process as claimed in claim 1 , wherein the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the range from 1:2 to 1:1.

7. The process as claimed in claim 1 , wherein the molar ratio of the styrene used in step a) to the isopropanol used in step a) is in the of 1:1.
