Question regarding extraction of THC from fresh Cannabis leaves.

Migrated topic.
sorry, ss pipe= stainless steel pipe.
aluminum should be safe with butane (although i heard martha stewart say "aluminum should never touch your food")
now i'm just being difficult, :) i know u want honey oil already!!
swim hasn't found any other suitable cap, so he's thinking of closing the top end off with a tightly spun Cotton rag instead of a cap with several holes.

remember butane is under pressure, and gets really cold as it evaporates.

The BHO Alchemist Machine(turn jigs to gold)

The BHO machine consists of 3 metal peices - sold as plumbing
The back cap peice - gets a hole drilled in it - and a small fitting from the butane can it pushed thru the cap.
The bottom reducing metal peice gets a coffee filter pushed into it - and the middle pipe gets packed with ground up bud.
An important thing to note is that that BHO machine works best at full capacity - so make that middle tube only as big as u intend to full it.

For small runs (under 2g) i have a BHO machine that is just the cap and reducer - no pipe.

Each packing gets 3 blastings of butane(wrap a cloth around the machine so u dont get cold burns - as the whole device freezes up)
 
yeah as fractal said swim prefer alcool oil too, it's really pure product if done properly and would be less pure compared with honey of 2% maybe? secret is wash your leaves fast and filter the solution. last year swim used a syringe filter of 0,45 micron and his oil rock candied :p
pfff butane will cost *a lot* more than alcool and you have idea and paranoia of smoking something semi synthetic you couldn't know if you oil is pure or adultered. imo use of butane is risky to give more impurities than purification
 
any alcahol(ethanol, ipa, methanol, etc) gives a far less desirable product than a something like butane, heptane, benzine or naptha.
iv tried every solvent iv managed to get multiple times on multiple kinds of bud - so i say this thru experience only.
 
ohh gosh phlux swim didn't noticed theese goodies :p :roll:
paki is yummy and this oil is very nice too
swim doesn't think ethanol or better ipa would give far less pure oil cuz purity depends by filtration,first of all,lab paper or coffe filter istead of a screen for example
and for second, time and temperature of solvent

swim thinks 2 runs of 10 secs or less with alcool would dissolve almost all trichomes in alcool,as sugar dissolve in water,no time to extract clorofill from cells maybe *traces* of salts.
ah and first of all,purity of solvent

example: 500ml solvent for 3ml oil.if solvent have 0.1% impurities it means than when all solvent is evapped it leave in my oil 0,5g of impurities in 3ml tha's a lot 0,5g of mercaptane or other shitty chemicals (speaking of butane)
with alcool really dunno, it seems to leave no residue when evapped,but who knows..
swim thinks most of alchol impurities are volatile about as alcool,so no problem when you purge your oil properly.


swim wanna your oil duuuck phlux!!!! :x yum
 
after hearing of butane impurities a while ago i emptied a can of butane into a dish - i saw no noticable contam.
u know that first stuff was very very active at 25mg - and thats to a heavy daily smoker.
 
uuuh lol 25mg is very little swim thinks with his friends used 1/3 peanut or about 150mg maybe 200 for 3-4 people and all was very fucking stoned,very different than smoking hash or weed,more body and head trance.. we always said hey! this is not light drug!! :roll: :lol:
it would least for 3 good hours i think. swim loved put it in a chiloom, last hits are almost deadly lol
swim found very usefull mix maybe 2 parts of tobacco to 1 of oil and than use it as a chunk of hash cutting it to little pieces with shissors.
this shit is damn annoyng to manage :x
 
Yeah SWIM's been wondering too wether or not the fact that a solvent leaves no stains uppon evaporation is a good indication of purity.
But SWIM has been interrested in Butane because it's said that Butane will only solve desirables and not dissolve chlorophyl.
Yesterday SWIM filtered the Diethyl Ether extract of the Cannabis leaves into a glass jar; It is poisonous green with Chlorophyl. And still evaporating out solvent. SWIM wishes to make a pretty pure hashoil extract without Chlorophyl. Does IsoPropyl Alcohol dissolve Chlorophyl or not?

Also SWIM wouldn't really know in what store/shop he is likely to find IsoPropyl Acohol( which is what SWIY meant with iso, right?)
He knows where to order it, but when it comes to solvents he prefers to anonymously buy it from a store with cash rather than to order it over the internet.
SWIM recalls buying a small bottle of cleaning alcohol in a drug store that was Denatured; Deliberately poisoned to make sure people won't ingest it as cheap means of getting drunk.
SWIM fears allmost all commercially available high %-age alcohols may be Denatured.

Can SWIY suggest any shops/stores where SWIM is likely to be able to buy pure, uncontaminated IPA?
 
etanol for drinks is clean...iso i dunno,i think only lab grade is safety.swim hase never extracted clorofill with etanol, always obtained a pale yellow solution and oil caramel colour
 
that BHO looks like a tasty treat, phlux, nice one!

have u ever run hashish thru your extractor with butane instead of green matter?

have a look at this article, and i am not endorsing bubblebags, there are many others out there, i chose this one cause of nice pics...
pure ice water is a safe solvent. it does not extract chlorophyll.
look how pure the resin is with just simple silkscreen filtration.
think how little solvent (of your choice) would be necessary to dissolve and filter glands like this....

20 Gallon bubble bag run using BUD ( and hand mixer)

Well this is my first bubblebag post on the new site, and im pretty exicted, i was gonna start off with the BUBBLENOWXL post, but i will show people that it is indeed still possible to produce full melt bubble, using a hand mixer. Now this batch was made last summer, so its a little old, as i do...
www.fullmeltbubble.com

the same is true for dry sieving!
 
water is not solvent for hash,it just scrapes the thrichomes from the matter
with bubblebags you can't go wrong but there's a lot of others cheaper bags that works good too. swim love full melt clear dome hash..73 microns is oooh god! just fucking delicious :p
 
yeah - nothing better than a fat chillum full of bho between good friends :D

iv tried soaking hash in naptha - then filter and evap before - just like baking it - it made it loose its flavour.
best hash imho is home made bubble hash - followed by bho then screen hash (silk screen) just caus it takes 5 mins from bud to hash - using nothing but a screen and ur hands(and a card to scrape it up with)
 
"Mercaptane and other shitty chemicals" are impurities that SWIM could expect to be in commercially sold Butane Gas?

Guess SWIM will just end up ordering Ethanol over the internet.

I had heard of making this by refluxing in alcohol and hcl.
I have been thinking of trying the process someday.
Can you say if it is much different than BHO?

(edit)
I reread the techs and realized that I have the vocabulary wrong.
Decarboxylation refers to baking the hash in order to convert inactive THC into active THC, while what I described with the refluxing is called isomerization and does something somewhat different...I think?

I have read several claims that the reason that butane is such a successful solvent is that it only comes into contact with the plant material for a short time and causes it to be very cold. The THC oil that you seek is located on the outside of the plant material and the chlorophyll and other junk that makes for a green resin is located inside the plant material.

I suggest that you look at a recipe for QWISO (quick wash isopropanol).
You may very well be able to use your Diethyl Ether as a solvent without pulling any chlorophyll if you freeze your plant material and give it a quick rinse in the room temp solvent, so that it only dissolves what's on the surface.

uyeah mercaptanes are common impurities in butane for lighters,expecially the cheaper
Click to expand...
Why in fuck's name would they contain these impurities? Natural impurities from natural Butane sources that were simply never removed? Or are they added to dick around with strange, phytochemical-obsessed characters that seek solvents for certain, generally rather frowned uppon activities?

SWIM wonders wether there might be realitvely easy ways of purifying Butange gas using kitchen-chemistry?
If however purifying Butane gas is too complex for a kitchen-chemist, SWIM will move on to procuring either Ethanol or IPA for his extraction.

Oh well SWIM has not been succesful obtaining ethanol at the liquor store. He will try the oldskool pharmacy/drugstore soon. If they don't sell it he will try some hardware stores.
He seeks to buy his solvents straight from the shop, and would rather avoid ordering solvents online.

If he can not find Ethanol or IPA at the drugstore or hardwarestore, could anySWIY suggest SWIM in what stores/places to look for these solvents?
 
mercaptanes are added to give to butane different smell swim thinks,bad small too sanyway..
it's difficult to purify in at home almost impossible in swim opinio...you shall make fractional distillation but there're many problems as very low boiling point that makes your butane to evaporate at enviroment temperature, ice that will form for the cold temps,loose of butane if you don't works with low temperatures and high pressures..no way to purify it,you must pay and buy the purest one
 
So using Lighter gas Butane to create hashoil is a potential health risk?

Someone needs to tell erowid.org to take that BHO-extraction offline and upload a safe, clean extraction instead.
They even advise to use PVC pipe in the process!

What about putting the sticky plant material inside a silk(or similair fabric) piece of cloth, knot it closed and rub it up real good?
SWIM supposes that hash would just stick to the silk cloth? This would yield a gummy hash SWIM assumes.

The thing is that SWIM would like a nice pure oil, suitable for vaporising.
He wants to stop smoking Cannabis and vaporise it instead. For this he would like to have a nice oily extract.

What about using a press-system, much like the ones used to press oil from sunflowerseeds and olives, to press the oil out of the cannabis plant matter?

sorry mate,,,
i feel like we are going in circles here--i really am trying to be helpful

i have purchased in the past "quintiple refined' butane for refillable lighters. i think it was vector? brand.
if u were to do a bho, this would prob be a good choice. look for it at upscale tobacco/news stands. (if in usa)

to separate hash from plant matter efficiently you can do a dry sieve. plant matter must be very dry, and silkscreen (with appropriate mesh size) is tight around a frame. gently scraping and shaking knocks the glands off, and they fall thru the screen onto a collection plate. this is simple keif.

what u are describing wont work.

if u dont want to dry the plant matter, then it would be possible to do a ice water extraction in a set of silkscreen bags with lots of aggressive stirring. i still think drying plant matter is a good idea here, too. drying the leaves and buds makes everything less sticky, and facilitates better separation of trichomes from leaves.

if u are in usa, stay away from hardware store alcohol. it is all denatured. i feel this is a criminal act, but it is what it is--poison.
every state has different regs, so 190 proof grain alcohol is not always available at liquor stores. common brands are everclear and graves.
isopropanol alcohol (ipa) is at every grocery and pharmacy in usa. try to get 90%

u have options
