In the case where isomers often coexist in a natural essential oil as a raw material for producing isolated perfumes, citronellol and rhodinol which coexist in natural essential oils such as geranium oil, rose oil, palmarosa oil and the like are optical isomers. The boiling point difference of the isomers is small, and the effective separation of the isolated perfume is difficult to realize by using a common rectification process, so that the precision rectification has wide application in the production of the isolated perfume.
