Steam distillations
What would be some good plant material to do steam distillations on to get chemically useful oils?
I'm going to do it on some cloves.
I'd like to do it on some roses but it is winter here now and ordering a bunch of roses would be ridiculous.
Maybe some pepper?
Does anyone also know of a good distillation set up with 24/40 glassware? I had found one before but you had to buy the entire kit >300$.
I have the condensers, RBFs, heating mantle, etc - I just don't know of an appropriate housing apparatus for the solid material. (I've heard that
having a mixture of solid organics / water is less efficient than the steam simply running through the solid organics).
...thanks

Do you live near a swamp/sea shore? Look for bay leaves if you are in the right climate - they are ever greens, You can get eugenol from them.
You could also distil some orange peels or pine needles.
(Orange oil in methanol strips anything off of anything)

Rosemary? I especially love the fragrances of spices. Oregano is another one. What about wintergreen? Where I live, wintergreen is just a short hike
away, even during the winter (duh, winter-green).

I don't recommend roses for beginner,because the yeild are so low.
You can distill bunch of it and only got a drop of it,though.
Beginner will sure be bored if trying to distill this for the first time.
Anyway,the hardwork worth it,roses oil's fragrance are so strong that if you dilute small amount of it in large amount of water,the fragrance will be
clearly noticed.

I attempted winter-green (or some other in the mint family) - I either picked it too soon (not sure?) or didn't have enough. I somehow ended up with
an aqueuos green distillate that reaked something awful. No visible oil, but the aquoues was cloudy. Not sure how chlorophyll got into the distillate
but I guess.
I use orange peels to get paint off my fingernails - works like nothing else  .
Does anyone know the name of the "bulb" for distilling? I have trouble finding it. Its just a large bulb, like a RBF, but has an additional neck at
the bottom of the bulb.

It is called an "alembic" - still can't find one for sale though.

You could probably get away with using a kuderna-danish flask.

Yes, unfortunately the joints are not fun - one is 19/22 and the other is 24/40 which doesn't make sense to me!
most of my glassware is 24/40.

If you want winter green oil go for the inner bark of a Yellow Birch, the extract will be low in the winter.

I think you mean black birch/sweet birch (Betula lenta). I don't think that the methyl salicylate concentration is related to the sap flow, though I
could be wrong.
Probably one of the highest yielding things you could distill is orange rind. There is very little essential oil in most other materials

Clove oil is considerable amount. I distilled it in an academic lab with SC CO2. The amount, by eyeballing (can't remember numbers) was nearly 20%
v/v! We also hydrogenated the eugenol I think.

I am not familer with black birch, I does not grow where I live. A little google search on it suggests that it produces much more methyl salicylate
then the Yellow Birch (Betula alleghaniensis). I have not distilled any of the inner bark myself but I use it to cook while out in the bush and find
it is very strong - but I do not think the tree can be tapped for the sap the way Black Birch is?
I have noticed that the flavor and strength of the sap goes down as the season ends, but thats based on chomping on pieces not any sort of real
measurement.
So... go find some Black Birch if you have it... Sweet Gale (myricia Gale iirc) drupes may yield some interesting extracts, the catkins and leaves
certainly do.

What about sassafras?
The fragrance of sassafras is by far my favourite. It's a shame that safrole is carcinogenic. But what the hell, background radiation is carcinogenic
too . As long as you don't drink it, you should be fine.

Yeti-I know a man who attempted it large scale (55 gallon drum was his biomass container) - he said it was such a hassle that he decided to concede
and called up China.

I'm not surprised, steam distillation of essential oils is a very time consuming and energy intensive procedure. There is so little oil per gram of
substance that the only way to make it work is large scale. You can't dry the material because you'd bet rid of the oils in the process. You can't
mash up the material either because you run the risk of getting it to pack too tightly, the steam would then condense midway through your plant
material.
I wanted to try out some steam distillation for fun half a year ago, but considering my material constraints, it'll take a long time before I get any
steam distillation to work.
I do have some ideas on how to build a cheap steam distillation apparatus. If you collect some fairly large tin cans and get rid of the bottoms, you
can stack them up to make a column, which you can fill with leaves and what not. The steam generator is fairly straight forward, just save a similarly
sized tin can and make that the bottom of your still where you will boil the water. Make sure you put some kind of separator so as to prevent plant
matter from falling into your steam generator.
seal everything with some duck (not duct) tape.
[edit]
Forgot about the condenser. For the condenser, take a polyurethane tube and make a "U" or coil in a tub of ice cold water to get the vapours to
condense.

Given the weird solvents you get in plant oils, you may want to make your diy condenser out of something like copper, glass or stainless to insure
there is no leaching or absorbing going on with the tube.

You're right, but I don't think there's enough oil in plants to react with the tin cans.[speculation] tin cans are designed to be quite inert, so they
shouldn't react with anything that is derived from plants at least not at the concentrations found in unrefined plant material [/speculation off].
Sidenote: Does anyone have one of these bad boys?
[edit]
I'm sorry, I misread your post.
You're right again, I should make the condenser out of something more inert, copper is expensive, glass can crack. How about bubbling the gases
directly into some cold water. The oils would simply float to the top where they can be poured off.

Actually that may not be true. Although
controversial, there is considerable data supporting the concept of radiation hormesis. http://en.wikipedia.org/wiki/Radiation_hormesis
There is some evidence that people living in high background regions, such as those in India where there is a lot of naturally occurring Thorium, have
a low incidence of cancer and increased longevity. Although I have published papers showing that a low dose of radiation protects mice against a
subsequent higher dose of radiation, I would not argue that these data can necessarily be extrapolated to humans. But it has made me reconsider the
possibly beneficial effects of low dose background radiation.

A number of us do, you can find them for under 30usd if you keep checking EBay.

Any data coming out of Bikini atoll or from Ukraine that matches with the mice results?

Interesting...
I guess you can say everything is beneficial in moderation. I think that cancer really arises when one has a weak immune system. Outside factors can
influence the likelihood of developing a tumour, but the immune system is a key player as well.
With that said, I think the #1 cause for cancer is immunosupressant drugs, allergy medication and what not. It's no wonder why there are more cases of
cancer in the past few decades compared to the two or three centuries that came before.

For the derailment on cancer; go check "burzynski + cancer" by utfse - I watched the documentary with intense skepticism. but by the 11th court
charge, the tangental governmental patenting, and the FDA website backing up all of the occurrences in the documentary, I have conceded that he is
correct in his 'cure' for terminal brain cancers.
Back on subject - a soxhlet for 30$? I can't even get a reservoir flask for that cheap. A Soxhlet is good for not steam distillations

If you are just starting off I suggest either Lavender oil or Sassafrass oil. Both are high yeilding and pleasent to the senses. Cloves however have a
certine bite that would quickly make you despise the scent of it in short order.

Sassafras oil is less than 1% w/w. Getting my hands on some safrole would be excellent (for the authorities).
Actually I've heard American sassafras has no safrole, only asian varieties/species.
