as said in the title, I'm looking for a home made method to extract oil from plants like bay laurel, mint, etc... I do not live in the u.s., so it is not sure I can buy all the stuff you can suggest... thanks to all

This is probably one of the simplest designs

You don't need to use any lab equip, just some stoppered glassware and a heat source

>>698029
should i put heat system also under the second bottle?

>> No.698035

>>698033
It shouldn't be needed
Just run a test batch and see how it goes.
You will need to seperate the water and oil from the final flask though.
Also a diy condenser can be made by getting two lengths of copper pipe which slide into one another and connecting inside each other using fittings

Sorry if this is vage I'll do one in paint

Soxlet extractor.
You also need a separation funnel to separate the oil from the solvent and organic plant matter.

Safrole oil is illegal to extract.

You mean Sassafras oil, dont you?
I hate fucktards like you who has to go into what is illegal, ruins the fun for all of us.

You cant buy safrole, but sassafras oil is used for flavour, fragrances and in insecticide. You can buy the essential oil quite easily if you want to.

Also, do you even know how much root bark you need? Not to mention a BIG still, or a small one and multiple days of work to produce any decent amount.

>> No.698078

>>698076
Yes... that is exactly what it is created to do. Extract compunds from solids, especially if it has a limited solubility in the solvent. Youtube it, and you see how it works.

The solvent gets heated, drips down into the solids, gets drained off, repeat.... until you see that the solids are totally extracted of anything. On plants they generally turn more or less white.

Then you need to separate the oil from the solvent. Separation funnel is the best to do this with.
Then, you need to dry it of water, using salt, og better yet magnesium sulfate. Filter it off.

Unsure if you need to do this, but sodium bicarbonate wash would probably not hurt in case there are any acids, you then need to separate again.
Last step, evaporate the solvent.

Sorry, meant separate the solvent from the water/organic matter, using the separation funnel.
The oil should be in the solvent.

And you do that, how, exactly?

>> No.698294

>>698284
It dehydrates the solvent.
Salt is insoluble in most solvents, and will dissolve in the water remaining in the mix, making the density grater allowing you to separate them.

>> No.698296

>>698294
you then filter to get out any remaining grains of salt before separating them.

I've placed a copy of
"Guidebook to Constructing Inexpensive Science Teaching Equipment Volume II: Chemistry" on my public dropbox at:
https://dl.dropboxusercontent.com/u/3621645/Guidebook%20to%20Constructing%20Inexpensive%20Sc%20-%20Unknown.pdf

I believe this document to be public domain, and apologize profusely if it is not.

This book is designed for teachers and students working in third world conditions, and the apparatus should be constructable by anyone. Pic Related is the dead-simple distillation apparatus. A couple of pages after it is a plan for a simple water-cooled condenser.

Most plant essential oils are extracted by steam distillation. Hot Steam is passed through the plant material and then into a condenser. In the condenser the steam and oil move from the gas phase to the liquid phase. This output is collected in a container. It will be 90%+ water with a small amount of oil. If your container is a separator funnel, you can drain much of the water off without interrupting the distillation.

There are a large number of essential oil distillation videos on youtube. It is worth watching a few to understand the process.

I seem to recall one lady extracting ~ 25 pounds of mint for around an ounce of oil. Her still was a large pot of water connected to a 4 inch metal pipe packed full of mint connected to a homebuilt copper condenser. I was not able to locate the video for this post, but hopefully my description can give you an idea of the plant matter requirements and understanding of how the process works. (and that it doesn't always have to be made out of glass.)

Please post back with pictures!
