Tobacco extraction using heated Ethanol

[dannyv45]

Ahem; pardon the silly question, but why am I getting a strong aroma from some of these pipe tobaccos? Are they laced with flavorings? They apparently are, because none of the dry leaf tobaccos I know have that aroma. Curious if those flavorings are synthetic or natural, and why are they not at least mentioned briefly on the product's description? All they list are the various tobaccos that go into the blend -Nightcap, Louisiana Red and Firestorm -all from P&C. I like the earthy aromas, but what are they?

P.S. Should I air dry the tobaccos before extraction?

I didn't air dry. I just used as is. It would be good to know what the additional flavors are with all the health concerns surrounding vaping. nun the less they did come out very good.

I reduced my extract of nightcap down to 10% and mixed in some pg but it looks really opaque and dark. Is this the norm or have i ruined it as i saw bubbling during the heating using a double boiler.

This is normal with the nightcap. Mine came out the same way.

I have problems to find good paper filters in europe. I am thinking 3 mycrometer must be enough.

Is here somebody who knows a seller in europe ?

I did the unthinkable and rolled up a couple of joints after the extraction just to see any flavor (and nicotine) was left in the tobacco.

Tried two different dry leaves - Turkish tobacco and American Spirit Perique Blend. The Perique had given up almost all of it's flavor, but not the Turkish. I am considering increasing the extraction time accordingly.

More importantly, both tobaccos were considerably weaker in the nicotine department - an indication that the extract has pulled a certain amount of nicotine from the leaves. Estimates run anywhere from 5% to 25%. That may not be significant as long as we are not using too much of an extract in the final mix.

Search for Ahlstrom or Ahlstrom Munktell. Ahlstrom is a Swedish company that makes filters and Munktell is their German subsidiary based in Bärenstein.

here's the link for that filter bag I posted previously.

On my extract I used a needle polypropylene rated at 5 microns
needle prolypropylene filter - Google Search
its the green one...
only did the apple flavored and the final result after reducing it to circa 10% after evaporating was very dark. did't notice much oil but it was very sweet tasting and strong, overall pleasant. will post pictures tomorrow or Tuesday

Thanks, but i have to search it in europe, because a am german and dont want to wait for weeks. Its a needle which filters 5 microns ? Never seen before.

MONOJECT Filter Needles with Polypropylene Hub - 18 G x 1-1/2" - Allegro Medical Supplies

Is the needle better than a paper filter like this ?

Wow. Hope they will sell to private persons. In germany is another company who sells only to other companies. I am thinking about the 2,5 micrometer.

What do you mean ? Does it take many hours for filtering ? Can i fold these filters to put it in a funnel ?

I have written an email to Munktell. Many thanks

Wow. The retailer from the uk looks fine. Hope they will sell to private persons. In germany is a company who sells only to other companies. I am thinking about the 2,5 micrometer. What do you mean ? Does it take many hours for filtering ? Can i fold these filters to put it in a funnel ?

They sell both, Flat or Folded. I use the 70mm 2-micron flat filter with an Aeropress.

The faster the filter rate, the more the filter cost. Borosilicate glass filters have the fastest flow rate.
Filtering time can vary depending on extraction method. Ethanol extractions filter relatively fast compared to PG extractions.

............... Can i fold these filters to put it in a funnel ?

Often you can buy filters that are pre-folded for use in a funnel but if it's less expensive to get flat filters they're -very easy- to fold; http://www.google.com/url?sa=t&rct=...yXtFORQ0BxOgukRYQ&sig2=OeXAO0LxxtROkNu1-OFh0w

...........an indication that the extract has pulled a certain amount of nicotine from the leaves. Estimates run anywhere from 5% to 25%. That may not be significant as long as we are not using too much of an extract in the final mix.

Let's extract the tobacco contained in a single pack of cigarettes in 125ml of solvent and assume we were able to leech 25% of the nicotine from that pack using our simple soak extraction methods. We'd have 5 cigarettes (25%), worth nicotine in our 125ml of solvent. We'll lose 25% of our solvent (and also the leeched nicotine), due to absorption by the tobacco and filters leaving us with 100ml of extract with less than 4 cigarettes worth of nicotine in it. Since we can't vape pure extract straight we now mix it @ 20% with VG/PG making 500ml of ready to vape NET with less than 4 cigarettes worth of nicotine in it. How long will it take the average vaper to go through that 500ml of NET? The mathematical reality is that what little nic our simple soak extraction methods are able to leech from the tobacco ends up so diluted in the final mix that the major retail NET vendors offer it as 0mg.... The only way to get around this mathematical reality would be to not mix our extract, but instead to reduce (concentrate), it by 95% and vape the 5ml of tar like tobacco "absolute" straight, then the 4 cigarettes worth of nicotine could be used in a short period of time.

 

[Exchaner]

Agreed. That's why I said the amount may not be significant
I am not sure however if nicotine evaporates like alcohol does. Or does it?

 

[Str8vision]

Good question, I really don't know if nic suspended in alcohol would, at some percentage, evaporate off along with the alcohol. I would think most of it would remain but that's just an uneducated guess.

 

[jonnydoe]

I have found a filter at german amazon now. Thank you for the vid str8 !

Now i am waiting for all the good things i have bought. This will be my first explosion at home

Good question, I really don't know if nic suspended in alcohol would, at some percentage, evaporate off along with the alcohol. I would think most of it would remain but that's just an uneducated guess.

My educated guess: if it was as free base, some would evaporate off, but I believe it to be extracted as a salt so minimal evaporation ... of the little bit we actually extract. I assume it to be close to zero content, especially once we have diluted it down to form our consumable liquid.

 

[Exchaner]

I was hoping I could bypass the use of the fine filter by letting all the residue settle on the bottom of extract and carefully skimming off the top. But even with that approach, my coil is getting clogged big time - in less than 3 ml. The question now is, whether I could bypass the coffee filter and go directly to the fine filter - skim off the top, leaving the residue on the bottom, and go directly to the fine filter. That would minimize the loss due to absorption. Anything wrong with that approach?

 

[Str8vision]

You can always try it, but I'm afraid you might actually lose a higher percentage of extract that way (by leaving it in with the muck), or worse, inadvertently pull some of the muck out.

 

[Kingboomer]

OK back from some insanity. I never got the chance to try this with the mint, which is a good thing since it FINALLY died . I have a thought on concentrating the flavors: rather than heating the glass for evaporation, could one use a computer fan over the jar, pulling air out, to efficiently evaporate off the ethanol? Just a thought...

[Bunnykiller]

its do-able... it just takes alot of time... days instead of hours

 

[Str8vision]

Double extracts are proving to be more difficult to reduce, 50ml heated to 140F in an electric oven took -six- hours to achieve a ~50% reduction. Not really a problem, just an observation.
