Question

#2, why do we not perform a simple distillation on lemon grass oil at atmospheric pressure to separate the components? What's the advantage of steam distillation? Can you imagine another distillation method that might serve the same purpose? (See Padías, page 152) #3. Look up the structures of Carvone. Cuminaldehyde and Eugenol. Each of these natural products has similar structures to each other and Citral. Make a small table with the molecule names at the top of the columns and the two functional group tests as the rows. Indicate which qualitative test would give (+) without spectroscopic methods, to unequivocally differentiate these four molecules results. Is it possible, using wet methods? #4. Research the H-NMR of a mixture of neral and geranial (citral) from the Sigma Aldrich com web site Can you explain why there are differences, especially in the chemical shifts of the vinyl hydrogens?

Explanation / Answer

Answer:

Here, in this case, we look for a lower pressure so that we don't have to use as much of heat because of the

use of high heat can result in the decomposition of the citric acid.

when we want to separate two non-volatile substances

citral is good for steam distillation

the advantage here will be that in steam distillation the lower pressure reduces the boiling point, that is why less heat is required to perform distillation,

Another option is Vacuum distillation, also reduces pressure.

Thanks :)
