How it is made

Derivation: Citrus peel oils, especially from oranges. Made synthetically from geraniol. Method of purification: rectification.

It can be prepared synthetically starting from myrcene or from dehydrolinalool, it can be obtained by fractional distillation and subsequent recitification from the oils of Cajenne rosewood (Licasia guaianensis, Ocotea caudata), Brazil rosewood (Ocotea parviflora), Mexican linaloe, shiu (Cinnamomum camphora Sieb. var. linalooifera) and coriander seeds (Coriandrum sativum L.).

The pyrolysis of 2-pinanol at 500 °C gives linalool. (-)-Linalool is formed from (+)-cis- and (-)-trans-2-pinanol, and (+)-linalool from (-)-cis- and (+)-trans-2-pinanol. The process is used industrially.
