Repels insects due to strong smell |
|
(+)-Citronellol is found in citronella oils, including that from Cymbopogon nardus. (−)-Citronellol is also widespread but particularly abundant in the oils of rose and Pelargonium geraniums |
|
It is mainly obtained by hydrogenation of geraniol or nerol over copper chromite catalyst. Alternatively it can be produced by fractional distillation of the oil |
