4-tert-Butylcyclohexanol synthesis

7synthesis methods
From 4-terf-butylphenol by hydrogenation(Arctander, 1969).
-

Yield:98-52-2 99.9%

Reaction Conditions:

with hydrogen in tetrahydrofuran at 180; under 195020 Torr;

Steps:

1 Example 1
Example 1 A 50 wt.-% strength solution of p-tert-butylphenol was prepared in THF. Then 2500 g/h of this solution were passed with hydrogen at a temperature of 180° C. and an overall pressure of 2.6·107 Pa through a flow reactor, which was packed with 3.2 l of the Ru catalyst described above. Following removal of the solvent, by distillation, the hydrogenation product had the following composition: 99.9% of cis,trans-4-tert-butylcyclohexanol <0.01% of p-tert-butylphenol.
