Chemical Properties |
Citronellal has an intense, lemon-, citronella-, rose-type odor. |
|
Uses |
rac-Citronellal is a monoterpenoid and the major isolate in citronella oil. Citronella oil is an essential oil bearing insecticidal properties. rac-Citronellal is also often used as a fragrance ingred ient. |
|
Definition |
ChEBI: A monoterpenoid, the main component of citronella oil which gives it its distinctive lemon aroma. |
|
Aroma threshold values |
Detection: 31 to 100 ppb |
|
Taste threshold values |
Taste characteristics at 10 ppm: floral, green, rosy and citrus-lemon. |
|
Chemical Synthesis |
Can be prepared by chemical synthesis or by fractional distillation of natural oils, such as citronella. Industrially prepared by hydrogenation of β-citronellol or by catalytic hydrogenation of citral; also in the laboratory by dehydration of hydroxydihydrocitronellal. |
