| | DL-Isoborneol Usage And Synthesis |
| Description | Isoborneol has a piney, camphoraceous odor. May be prepared by
the hydrolysis of isobomyl acetate, or by catalytic reduction of
camphor (both d- and ι-isomers); the optically inactive compound
can be prepared by treating camphene with a 1:1 mixture of sulfuric acid and glacial acetic acid and then hydrolyzing the
isobomyl acetat. | | Chemical Properties | Isoborneol has a piney, camphoraceous odor. | | Chemical Properties | white to almost white crystalline powder | | Occurrence | Reported found in the oil of Abies sibirica and a few other essences and in the essential oil from roots of
Chamaeciparis formosensis. Also reported found in apple, papaya, blackberry, cinnamomum, ginger, thymus, cheeses, cognac,
Ocimum basilicum, rosemary, temoe lawak (Curcuma xanthorriza Roxb.) turmeric, sage, clary sage, ashanti pepper, German chamomile oil, eucalyptus oil and mastic gum leaf oil | | Uses | Used as a synthetic flavor, as a moth repellent, cold sore topical medication, muscle liniment, and steam-inhaled cough suppressant. It is also used in Used in perfumes. | | Uses | Isoborneol is a monoterpene and a component of several plant essential oils, showed dual viricidal activity against herpes simplex virus 1 (HSV-1). | | Definition | A geometrical isomer of borneol. | | Preparation | By the hydrolysis of isobornyl acetate, or by catalytic reduction of camphor (both d- and l-isomers); the optically inactive
compound can by prepared by treating camphene with a 1:1 mixture of sulfuric acid and glacial acetic acid and then hydrolyzing the
isobornyl acetate | | Aroma threshold values | Detection: 2.5 to 16 ppb | | General Description | Isoborneol is a monoterpene and a known antioxidant, which is a component of several plant essential oils. | | Flammability and Explosibility | Flammable | | Purification Methods | Crystallise isoborneol from EtOH or pet ether (b 60-80o). It sublimes in a vacuum. The 4-nitrobenzoyl derivative has m 153o. [Yager & Morgan J Am Chem Soc 57 2081 1935, Beilstein 6 II 80, 6 III 299, 6 IV 281.] |
