Abstract

Method of producing a taquiesterol or an ester thereof and of a dihydro-taquiesterol by tachy-sterol reduction, characterized in that a catalyst is added to a neutral or slightly alkaline solution of a pre-calciferol or an ester thereof; which is capable of transforming the cis isomers into trans isomers and where, if desirable, then the tachyesterol or the ester thereof is reduced to obtain a dihydro-taquiesterol with the aid of an alkali metal and an aliphatic alcohol.
