Abstract

The present invention relates to a process for preparing, 4-bis(ethoxymethyl)cyclohexane, which comprises reacting 1,4-bis(hydroxymethyl)cyclohexane with ethyl chloride in the presence of an inorganic base, a solvent and a phase transfer catalyst to yield a reaction mixture containing 1,4-bis(ethoxymethyl)cyclohexane, where the inorganic base is selected from alkali metal hydroxides and earth alkaline metal hydroxides and where the solvent is selected from water or a mixture of water with at least one organic solvent.
