摘要：
An improved process for the preparation of hydroxycitronellol by an addition reaction of water with citronellol. This reaction takes place directly on heating a homogeneous solution of citronellol in a mixture of water and an .alpha.-methyl-branched lower alkanol in the presence of a strongly acid ion exchanger.Hydroxycitronellol may be used as a fragrance material and is an important intermediate for the preparation of the highly desired scent hydroxycitronellal.
