Therefore, high-efficiency precision fillers are used to achieve the separation and purification of the components to be separated. In the production raw materials of isolated spices, natural essential oils, isomers often coexist. For example, citronellol and rose alcohol that exist simultaneously in natural essential oils such as geranium oil, rose oil, and palm grass oil are optical isomers.
