Steam Distillation- Isolation of Clove Oil / Eugenol

This video is dedicated to Fred Jackson, Biology (Anatomy and Physiology) Professor at the College of Southern Nevada. *Thus Dr. Rennels' shirt*
Fred was a valued and respected colleague, he served CSN and it's students with dedication for many years. He was well loved and will be deeply missed by everyone who knew him.
Everyone who knew Fred will understand that Dr. Roger Rennels' attire in the video is very appropriate!

If your chem prof is wearing a Dead T, you're in the right class.

Very explanatory

[@mercylnonari3807]

Thanks

Very nice, I process 1lb of cloves at a time and Instead of Dichloromethane I use Ether.

[@wizzbangchemistry9706]

ether is probably better but we use dichloromethane for the convenience of which layer is organic in the workup

[@ahmetselcuk1400]

Eugene demetylation video please

[@christinebell8240]

what would happen if too much water was left in the recovered eugenol during dehydration?

[@mercylnonari3807]

Weldone

[@kanzaabdulqayyum5129]

Which solvent we can use if want to use clove oil for oral use can you mention some safe options plz

[@kerobotros2501]

After steam distillation , why we didn't evaporate the water directly at 100c ?

[@nitaicrasemann]

to avoid the decomposition of the thermolabile compounds in the essential oils i think.

[@dalegregg2700]

Water solvent not quantitative ... why not use water to rinse clove residue into distillation chamber, to maintain quantity of clove?

[@mjames7674]

Could you still get the extract even if I don't have any dichloromethane or magnesium sulfate?

[@wizzbangchemistry9706]

you need an organic solvent of some sort to extract the extract from the water.

[@mjames7674]

@@wizzbangchemistry9706 Thank you for answering my question

[@chromatogiraffery3104]

It works fine without solvents, eugenol is denser than water, so it phase separates below the water. you can directly remove it with a pipette. The yield suffers, though, you lose a lot, stuck as tiny suspended droplets, hence why organic solvent extraction is more efficient.

why dichloromethane

[@wizzbangchemistry9706]

There's better solvents but we use dichloromethane because it's easier for students to work with if it's the bottom layer in the sep funnel.
