Gas extraction

[hardraade]

Im looking for a substitute for butane, (and co2, since I dont got the equipm.to make it safe enough DIY) Its certain aromatic oils in some swiss seasonflowers, that I want to extract without getting all the other fatty stuff\lipids in the extraction..Butane is too dangerous, and co2 needs far to high pressure too work with.

(I have to do several runs)

I've heard of steam distillation, and hexane extraction method. I don't know the details though..

Yes, Im thinkin of the steam-way. Ive worked with steam-destill.\separation before, Its called a Kjeldahl's destillation.

But I dont know what the steam would do to the lipids and arom.oils mentioned in my init.post.

Could I use low temp.instead of the superheated steam?

(I mean, when ure working with inorganic, u can speed up the dest.time and the yield of dest. If the steam is led over a 10 cm.section of ironpiping,thats being heated with some sort of el.element or if u're working with good ventilation\nonflammable solvents u can use a propaneheater or a kind of bignozzeled blowtorch, on lowest output from a distance, just after and just before its led into the Drechscler-pyrex. So the steam holds about 2-300 C.)

 

But in this setting, I guess its the respect.temps of decomp.that sets the limits?

Could you please type full words? If people find it hard to read they won't respond to you.

 

Apparently hexane works well but will leave about 10ppm residue in the oil once you get it out. Do you have a photo of your setup, I'd like to see?
