The determination of aldehydes and ketones is of importance in the analysis of those essential oils characterised especially by aldehydic or ketoruc principles, e g.,the citral contained in lemon and lemongrass oils, citronellal in citronella Oil and some eucalyptus oils, benzaldehyde in bitter almond oil, salicylaldehyde in meadow-sweet oil, anisaldehyde in aniseed and fennel oils, cuminaldehyde m cumin oil, cinnamaldehyde in cinnamon oil, carvone in caraway oil, pulegone in pennyroyal oil and methyl nonyl ketone in rue oil The determination of the aldehydes and ketones presents, however, difficulties and the above methods are moderately exact in only a few cases, especially when the content of aldehydes or ketones is considerable The bisulphite method is applicable particularly to the determination of cinnamaldehyde and benzaldehyde in cinnamon oil and bitter almond oil, and, up to a certain pomt, to that of citral in lemongrass Oil. The sulphite method gives good results in the same cases and for the determination of carvone and pulegone... 

The carbonyl number method gives moderately exact results for the determinations of benzaldehyde in bitter almond oil, of cuminaldehyde in cumin oil and of methyl nonyl ketone in rue oil. The method devised by Hanus gives, according to this author, good results for the amount of cinnamaldehyde in cinnamon oil.

Identification The infrared absorption spectrum of the sample exhibits relative maxima at the same wavelengths as those of a typical spectrum as shown in the section on Infrared Spectra, using the same test conditions as specified therein. Assay Not less than 90.0% of ketones, calculated as methyl nonyl ketone (C11H22O).

Undecanone (methyl nonyl ketone), a natural nontoxic insect repellant compound, was recently isolated from the trichomes of wild tomatoes, and is currently being introduced as a replacement for insect repellants containing N,N-diethyl-meta-toluamide or DEET, which are permitted for use only on children older than 2 months. In an effort to improve the delivery of the somewhat volatile liquid 2-undecanone, we have successfully formed the crystalline inclusion compound (IC) between 2-undecanone and a-CD, using a coprecipitation method [69,70],...
