Beschreibung

Citronellol is a kind of natural occurring acyclic monoterpenoid which can be found in citronella oils such as Cymbopogon nardus ((+)-citronellol) and rose oils and Pelargonium geraniums ((-)-citronellol). In addition to be extracted from natural oils, it can also be manufactured by the hydrogenation of geraniol or nerol. It is mainly used in perfumes and insects repellents as well as being used as a mite attractant. It should be noted that it is an excellent mosquito repellent at short distances. Combination with beta-cyclodextrin can make it has an average duration time of 1.5 hour against the mosquitoes. It can also be used for the manufacture of rose oxide. One of its most common applications is for adding floral and citrus notes to perfumes, soaps and cosmetics.

Chemische Eigenschaften

Citronellol has a characteristic rose-like odor. Because odor plays such an important part in selecting this material, there may be special grades of citronellol that do not meet the Essential Oil Association specification. These limits have been broadened enough to include best qualities of commercial citronellol and chemically pure citronellol. l-Citronellol has a sweet, peach-like flavor; d-citronellol has a bitter taste.

Occurrence

l-Citronellol has been found in the plants of the Rosaceae family; d- and dl-citronellol have been identified in Verbenaceae, Labiatae, Rutaceae, Geraniaceae and others; citronellol has been reported in about 70 essential oils and in the oil of Rosa bourbonia; the Bulgarian rose oil has been reported to contain more than 50% l-citronellol, whereas East African geranium contains more than 80% of the d-isomer; the natural product is always optically active. Reported found in guava fruit, orange, bilberry, blackcurrant, nutmeg, ginger, corn mint oil (Mentha arvensis L. var. piperascens), mustard, pennyroyal oil (Mentha pulegium L.), hop oil, tea, coriander seed, cardamom, beer, rum, and apple juice.

Verwenden

citronellol is a constituent of plant essential oils. Found abundantly in eucalyptus oil. It is used for masking odor or providing a fragrance component to a cosmetic product.

Definition

ChEBI: A monoterpenoid that is oct-6-ene substituted by a hydroxy group at position 1 and methyl groups at positions 3 and 7.

synthetische

By reduction of citronellal or geraniol or by fractional distillation of such essential oils as geranium and citronella (Bedoukian, 1967).

Allgemeine Beschreibung

Citronellol is a volatile monoterpenic primary alcohol mainly found in the essential oil of plants such as Pelargonium graveolens, Cymbopogon winterianus and Rosa damascena. It is also one of the glycosidically bound aroma compounds in ginger.

Sicherheitsprofil

Poison by intravenous route. Moderately toxic by ingestion, skin contact, and intramuscular routes. A severe skin irritant. A combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALCOHOLS.

l?uterung methode

Purify them bydistillation through a cannon packed (Ni) column and the main cut collected at 84o/14mm and redistilled. Also purify via the benzoate. [IR: Eschenazi J Org Chem 26 3072 1961, Naves Bull Soc Chim Fr 505 1951, Beilstein 1 IV 2188.]
