Question

"Rose oxide" is one of the components present in rose petals that gives roses their characteristic odor. Rose oxide has a boiling point of 230 °C, but might possibly decompose before it reaches this boiling temperature. Why might steam distillation of rose petals be the preferred method to remove rose oxide from rose petals? Explain your answer.

Answer 1

Analysis of rose oil from the Damask sole resulted has in the isolation of more than 100 organic compounds, whose Structure have been elucidated resina spectroscopic techniques including M5. It is no surprise that citronellol is the major component interestingly almost entirely as the S enaration Next comes gerraniol followed by nes - the only difference between these two ralcohols is the arrangement of groups around one of the cac Double bond. In gerraniol, the methyl (CH₃) and emoH group are on the same side and it is called the E isomer This means these alcohols have different shapes and while they both smell nose like, geraniol smells. more flowrry and heaol more fresh. .Reducing the E or a cac bondin geraniol or new by adding hydrogen to vorms citronellol, Next on the list is B-lonone, containing both a six membere.

toring and a kefore group, it has similar aroma to that of violets, finally there is cis and trans - rose oxide , which is discussed in below. Concentration of major fragrances OH "Citroneliol 35.9% geraniol 25.7% (151. of the other enantiomer) nesol 3 . 7. 애 B-lonore l'8y. -OH - rose oxide o.si Trans boscoride 0.4% (violet)
