Résumé : The epimerisation of the cis and trans isomers of 4‐tertiobutylcyclohexanol is studied quantitatively in the case of potassium in benzene as an agent. A general theory is formulated for the epimerisation of conformationally homogeneous cyclohexanols by monovalent agents. It has been shown that, in such conditions there is a linear relationship between the equilibrium titres of the trans derivative and the titre of the cyclohexanolate present. By extrapolation one may obtain experimental values of the conformational equatorial axial equilibrium of both the free alcohol and the corresponding alcoholates.
