Colorimetric methods for determining organic functional groups. II

Essential oils and related products

“…Andersen et al (19,20) proposed certain biogenetic implications of the antipodal sesquiterpenes in vetiver oil, and further supported this biogenetic theory with studies of the structures of vetivenenes and vetispirenes. Mac Sweeney et al (480) also reported experiments which illustrated the possible in vivo rearrangement of vetiver oil sesquiterpenes.…”

“…Cerium sulfate colorimetric methods for determining organic functional groups were minutely examined by Nazimowitz and Ma (480) as to the effects of temperature, time, reactivities, and other factors. Buttery et al (95) confirmed theoretical predictions that at 25 °C the higher molecular weight homologs up to C-9 in series of aldehydes, ketones, and esters in dilute water solutions are actually more volatile than the lower molecular weight homologs.…”
