Title: THC butane extraction: A theory
Post by: mr_happy2 on November 25, 2001, 03:56:00 AM
Ok, I've been playing around with the simple butane extraction of oil from cabbage and found that the ammount of butane needed to get enough oil was quite high (I would have to use 4 250ml bottles to get maybe half a capfull :( )

I was thinking that if it was boiling at room temperature, then maybe it might be easier to place 3-4 cans worth of b (thats what its called in our group  8) ) into a container, add 1 oz or cabbage, put a lid on it, and freeze.

I dont know what the boiling point for butane is.... does anyone here know?? would doing this give the butane more time to reach into the plant and take what is needed?? Something for all to think about......

SWIP also got poor yield on the butane extractions, and favored using acetone.  Not as selective, but much easier to handle than C2H6...

* Can anyone come up with a way to extract the acetone extraction with butane, thus perhaps getting more of the goods out with less solvent waste?

Butane is C4H10 . C2H6 is ethane.

interesting how everyone got a bad yeild  :( , but the question I have to ask is does Acetone give same quality oil as butane?? Butane oil is very concerntrated (sorry about spelling..... I have no excuse ;D ) and can really get you quite well toasted. Does Acetone give similar results, i.e Colour similar to golden syrup, and an almost non-existant taste?

hello its nice to be back i know how to pull more i dream about pulling about 6 grams a can with the lighter butane not that much smell in it first dont use the plastic pvc leaves a film on it on first couple pulls. u need to machine something to presirize the butane i dreamt about making a metal tube with to caps on the end one end there is a one way valve i dreamt about getting from a refillable lighter the other end i dreamt there was a gas valve i then put the cabbage in the tube and sealed it o ya i allmost forget the important thing there was lock nuts on both caps i blow a couple loads all over the room while laughing because it left a mark on the wall when it blows u dont want to get hit by the cap it will leave a nice dent in your head if u get hit by it ok then i butane in it intill the can wont take any more then i put the tube in dry ice in a ice box to keep it cool and let it absorb in the cabbage after letting it sit for a hour i then called the pizza guy and jacked him for his bag  i took the core out of the pizza bag and plugged it in the wall to get it nice and hot i put the pryex glass dish i found and a 3.5 metal slide part for a scraper then it was time to pull it i opened the end and let the liquid drip out u will c the butane start to boal off no water moister with the heat core only 1 problem i need help with i pull the green tint to its not honey i heard if u put it in alchole it will take it out but is that true if so i would then say this is the best way Ive ever dremt about

mr_happy2:  The oil obtained from acetone is black, has what I consider to be the usual hash taste, and will get you very much stoned.  SWIP could tell the C4H10 was better, but he only was able to get ~1g per 1/2oz (4x tried, 3x used different green). From acetone, he got 3.5g per 1/2oz, but it will induce massive caughing fits.  Also, used some grain alcohol back in the day (didn't know any better), and got a green oil (chlorophyl (sp?) contaminated) that still was able to get one well stoned.

PB

BTW, on larger scales, I thought I read somewhere that acetone soak for one week was most efficent means of extraction. Am I mistaken?

I think if you let it sit long enough or let the temp get above -45 then you get green too.  With hexane I got thick green paste.  Never really smoked it so I don't know if its potent.  Why on earth smoke that shit when there is nice green nugs around?  I want to roll a HUGE joint(kind nugs) with a about 3 grams of hash oil in the middle and bring it to a party.  That would bee fun to watch!!!  I wouldn't even tell anyone its from me, just pass it along. :)

'Tis best to first use an easy-to handle, safe solvent, then re-extract with a small amount of the nasty ones(i.e.Et2O). Since butane boils at close to zero degrees C, use an ice/salt cooled condensing tube( copper coil OK) and let room temp reflux your butane. Make a nice little soxhlet baket for the best extraction. Much less solvent needed this way, and less BOOM potential.

ether is good, but brings out some waxy - cellulose type stuff. incredibly powerful, paranoia-inducing sh*t. words just can't describe the high. i would like to isolate a little of it by GC and then run an NMR to see just what is in there. if you're wanting to re-evaluate every facet of your existence with white-knuckle intensity, i recommend the ether extraction on an immature plant of high quality northern lights strain.

Now I'm wondering if it is realy woth the effort to react the oil with H2SO4? What is the expected increase in %THC? Man, I wish I had some AA to make some THC acetate (among other things).

In the experiment im using a aluminum tube would it be better to use copper? Im using the tube to pressurize the butane to keep it a liqued is this not the right way to do it? Im getting good pull but lots of other stuff than yummy hash to. To much chlorophyll to i heard isopropal can fix this but i dont liek soaking it gives a bad taste.

Why not use Petroleum spirits. It can't be that hard to get, can it! Swim uses 40-60 grade. The oil that comes out is as gold as my fillings! Good enough as it is. And magnificent when cleaned with activated carbon.

Swim thought about using Butane, but swim wants to recycle all that solvent. Petroleum Spirits is great, but then swim has glassware.

I would like to see a nice way of pumping down that Butane and recycle it through a soxhlet. Then swim would use Butane.

FF

i like the postes and thank u for them. I am interested on the co2 method. but how would u get to pump a 1000 psi with?
maybe a paintball gun and pull the trigger a couple hundred times? only one wrong thing those post r a year old. acetone leaves a film. ether havnt done. camping butane scented cant use that. only thing that is worth using is the lighter butane but it cost to much. i pay about 2 bucks a can and am able to buy in cases witch is 16 if i rember right. made the tube for the pressure have set screws to hold on only blown them once. Damn tube caught on fire dont do around a pilot light. well keep posting i want to be able to perfect it some time soon. i got the isopropyl today going to figure how to get the green out. i need partners to help work with me on this. leave a message to me if u have any info that might help. thanx

One dream I had was to extract via butane, but the device that it emptied into was they center of my dream.  It was emptied into a clear glass (beer) bottle.  Unfortunately, my tube had several holes on bottom (not recommend) so a funnel was used to get it in, but what got stuck to the funnel was recovered with isopropal alc. Reasons this is good:  The way that the bottle is naturally allows for a slight reflux condition without ice and stuff(probably better with ice;  The tube should be WELL attached to the funnel which should be well attached to the glass bottle.  This kept the reflux going forever.  Also, the product is in its final resting place at that point.  When you are done, just hold the bottle over a gas stove with your thumb blocking the opening.  When your thumb gets pushed out, stick a straw in there and suck.  This works amazingly well.  As a side note.  If you wanted to isomerize, the bottle might be able to handle reflux heat (i guess isopropal would be used as a dilutant, but i have not isomerized so I dont know).  Then I woke up.

IM really surprised u didnt blow your self up in your dream. I rember when swim whas doing it and he forgot about hte pilot light and blew the cap off breaking his tube. It bent the lock screws and allmost killed him when the cap flew accross the room like a bullet. It took swim 3 good huff and puffs to put out the fire. If u read my choppy post above it describes one of the better ways to do it. The pvc plastic is not the way to go. 1 it breaks after enough uses plastic gets thin and flakes apart. I recommend using a small in diameter metal tub about 10 inches long. You will need lock nuts unless u want to get hit in the head with the caps. Swim has let it sit full of butane in the bottom of his pool. Let it sit for a while you will get more pull. One 2 dollar can of lighter fluid can pull u about 5 grams . Around here it goes for anywere from $150-$300 a half gram.

P.S. pls keep this post alive

Its funny that you said u get some "green stuff" with your extract because I have never gotten anything other than the honey oil color.  PVC is not the best way to go IMO because of the fact that i may be getting a little bit of PVC with my oil(nothing noticeable, although my throat gets irritated more easily with this stuff?)  As my thinking goes,  Pressure is not what u are specifically after here. My guess isthat u pressurized to keep it as a liquid and help the effeciency of the extraction, but... The more pressure, the more crap that gets brought out with your oil.  Butane is not "perfectly" selective.  Yeah, u seem to be getting the best yields, but if u wanted stuff that u had to purify then just use acetone.  Maybe, surround your tube with another container holding dry ice.  All objects can be kept as a liquid by either pressure or temperature so this should allow all of the butane to leave your tube before it converts into a gas bringing all of the goodies that it can with it (maybe there is an ideal pressure that will bring the most oil with the least crap).  Also, in theory, if u connect your tube firmly to the collection device, then as the liquid in your collection device begins to boil off, it can only go back into the tube where it gets cooled off(definitely have to use ice or dry ice for this to be worth it) once more, reconverted into a liquid, and emptied into your collection container. I may be missing something, but it should work, right?

P.S.  Just trying to help not argue.
Title: Re: THC butane extraction: A theory

To start it off i dont want to argue eather its a waste of time and effort. We will never meet unless u r wearing a badge and i hope  thats not the case with anyone here. OK now that I said that yes dry ice is a must or something cold. Yes a dish is needed to drop the liquid in i think a pyrex cooking dish works the best. Yes a heat pad is needed for the dish. I have done the pvc way and all i pull iss honey. Really bad yeild not worth it in my opnion. Now swims stuff is just as strong as the honey it just taste like shit. Swim did it right once and had shit tasting like pine one hit sent u to the floor which followed up with many hours of sleep. I dont know if pressure is what im after u cant use acetone bad film. You will not be able to smoke with out noticing the taste. Swim did that way first soaking it in acetone,alchole {grain and rubbing} and still just nasty black gew,yes very potent but swim is taking his triming and trying to get what he can out of them. Now with the better the trim the lighter the green is in the end. Why is that? With seeds and stems it turn allmost black a very dark green. Is this becasue there is more oil in the seeds? Swim is waiting on more trimmings intill he can try soaking the stuff in alchole. I read a long time ago to do this after you have the honey . Yes pvc cracks did u try it with a metal tube? Swim has not yet. Swim sticks to the pressure and is trying to perfect. Swim made blond hash once the only time he will ever do it. He said way to hard and takes to long. Who wants to beat something for hours with a beer bottle? Not swim or I thats for shure. Ok thanxs for the post and get back at me with more ideas


P.S. I just got done reading your post again 311 and a device to bring it back in is a very good idea I dont know how Swim would construct something of this idea. Pvc breaks down after enough use it will fall apart, like if u left it in the sun for a long time. R u  using a silk screen or panty hose on the end of a open tube? With a little work we can perfect this!! I can see it now Swim turining into a cash chucker . hehe i cant wait

it dose seem that leaving the butane to soak the cabbage would be the way to conserving butane and getting the most bang for your buck.
try cuting the valve from an empty butane can.
mill it down with a dremel to fit a 16 oz soda bottle.
cut a 3/8 hole in the center of the soda cap.
pop your homemade valve into the hole.
replace the blue gaskit also with a 3/8 hole.
put your cabbage into a clean dry 16 oz bottle cap it.
charge with butane as one would fill a lighter.
soak untill heart's content cover with 1" of butane.
chill the aparatus below 0 c.
slowly remove the cap cover with coffee filter rubber band ,remember pressure
pour the liquid into pyrex and process as normal.
remember to tap the filter when finished.
3 extractions are possible.
I love the hive !

Recently tried naptha, and found its selectivity to be somewhat better than acetone, though similar to xylene/toluene.  Still, no match for butane...
