Citronellol - Shitoronero-ru (English spelling) citronellol

A chain monoterpene alcohol. It exists as a mixture of α- and β- in many plant essential oils. Citronellol has one asymmetric carbon atom, and therefore exists as dextrorotatory (d-isomer), levorotatory (l-isomer), and inactive (dl-isomer, racemic) optical isomers. Citronellol is contained in citronella oil and geranium oil, and is a colorless liquid with a sweet rose-like scent. Its flash point is 102°C. Citronellol fraction is obtained by rectification of citronella oil, and is refined to produce the product. It can also be obtained by catalytic hydrogenation of citronellal. It is used in floral blends such as rose, lily of the valley, and lily of the valley.
