Butane Extraction Method?

That kind of method is what I'm offering an alternative to with my Prepetual Motion Goodness Extractor. I admire the ingenuity I've seen in these "one-pass/total-loss" solutions -- and I've seen them used -- but I've got a little paranoia about the smell and the fumes, as well as the economy and safety of using all that butane, or alcohol, for that matter. I don't think I can move all the THC out of the donor stuff in one pass, and I think it calls a lot of attention to myself to shoot a couple or three 8oz cans of butane into my backyard air.

But my Prepetual Motion Goodness Extractor With a few modifications will do much more than a prepetual butane extraction. It's a still. So by separating the expansion chamber from the collection chamber you can separate alcohol from cheap vodka. Although more expensive than butane, it stinks less, is safer, and it's still cheaper (and stronger) than everclear. The modifications basically amount to removing the extraction chamber and routing the flow from the bottom of the coil to a pop bottle, and using a heatable, sealable vessel like a pressure cooker for an expansion chamber instead of the mason jar. Of course you need a better heat source than a mixing bowl of tap water, too. Butane boils at about +30f, but pure alcohol boils around +170f, and impure vodka might take +185f to build up enough vapor to run to the coil.

Also, if you add valves in the right places you can trap the solvent in the coil, change out the donor stuff or reconfigure the device, and restart the process without a significant loss of solvent. I have valves at the top and bottom of the extraction chamber, top and bottom of the coil, and at both of the ports in the expansion chamber lid. I can separate the solvent from the goodness and drip it into a glass bottle when I'm done, put it in the deepfreeze, and reuse it next time. This control, economy, and better safety makes the effort worthwhile. It's also fun to watch!

Damn .... let me read all this shit, see if I understand it, and get back to you on it. What I really only want is the THC in its purest form to use as a tincture. Right now I use about an once of the best herbs I can find per 375ml 190pf EverClear. It takes about 30 days though to extract the THC using a cold extraction methode used. But it works. A couple drops when I'm done and I'm feelling nice without all the ephoria (sp). Its a lot more mellow, but relaxing just the same.

I was hoping a butane methode would extract the THC faster so that i could just mix it up in the 190pf EC and tincture myself away. I'm definitely still interetsed in your methods though. I also appreciate the time you took to type all that shit. Let me just sift through it and get back to you all.

Thanks,

just use 91% or 70% ISO and a very short shake period..2 minutes is about right with cleaned buds, trim or shake...the longer you shake/soak, the more green you get [that is not what you want]...at 2 min your yield should be amber colored and relatively hard when evaporated dry...ISO is about 1/10th the price of everclear...if you prefer a tincture, you can always use a little everclear to keep your product liquid and ready to use...

yeah but that 'green dragon' shit is just plain nasty. save the ispropyl for cleaning the keyboard or starting cool little fires. that method rodekyll posted is probably the best around for a nice, fairly clean oil and one i used to use...before reading up on and buying a set of bubblebags! bubblebags are the only way to go...!

I've done both the alcohol and butane extraction methods. If you don't like the green syrup that the alcohol presents (and who does?) butane is your solvent. The green is clorophyl (so I can't spell -- so what?) and other gaggy stuff. I've separated the green out of alcohol extractions, but it's messy, stains everything, and tastes more like the tar you scrape from your pipe when times are hard than essential oil.

On the other hand, The butane extract is a cheery gold color from the get-go. Butane doesn't seem to pick up the green much at all, and the post-extraction separation of the desired goodness and whatever else the butane leeched out is done quite simply with reagent alcohol. The good stuff is carried in the alcohol, and the rest beads up on the bottom of the container.

I use the same apparatus I described above to re-distill cheap vodka. Two passes thru the still (first pass at 190f, 2nd pass at 175f) and the resulting moonshine won't float a hydrometer at all, so I don't know exactly how pure it gets. It burns bluer and hotter than everclear though, and evaporates more quickly too. I use this stuff for post-extraction processing with good results. I've tasted it too -- pretty nasty, but a spoonful will give you about the same buzz as a black russian . . .

If you folks like cooking with this stuff, the butane extracted product is almost impossible to taste in anything I've added it to. Budder tastes like herb butter. Brownies taste like brownies. I don't advocate ambushing people with laced brownies, but it's certainly that undetectable. I can't say that about the alcohol extracted oils, or about the kiff/powder hash products.

I used a 1:10 ratio good chrone to EC for thirty days and I had to drink the whole bottle (50ml) to get even the lightest head change. If i where to ever do it again (which I wont) I would use a 1:5 ratio instead. I've get my weed for free so I wasnt trippen. I was just disappointed in the whole tincture thing.

Butane is next for me. :thumbsup:

hehe yeah the high is great. the taste is nice but the high is very strong and lasts way longer (for me) than with normal hash.
i think BHO (butane) and ISO (isopropanol) are about the same quality, to be honest i dont know the difference between BHO and ISO-oil except for the method of extraction
Ive made some butane honey oil yesterday (and today)
ive used a pipe, some screen, tape, 500ml gas, a piece of iron in which the gas goes and of course the trim..
put the screen on the pipe, put the trim in there, put the iron thingy on top of it and put the gas down there.
the cannabinoids will come down with the gas, into a container. the gas boils at 0C, so after some time only the oil will be left in the container.
I have had some problems (the trim was too tight and didnt let the gas through in the end) but i managed to get some fine quality BHO from trimmings only.

I haven't tried the Butane yet, but I did use the 1:5 ratio ... worked out a lot better. 2ml-3ml got me f*ck'n stoned!! I didnt wait the thirty days either or cold extraction method, instead I gave the EC/Weed mix a water bath for a couple minutes. Gota be careful though, EC is highly flamable (learned the hard way).

Anyway, just wanted to say that in about 10min time I had a nice 60ml vial of pretty potent tincture.

Still wana try the Butane though,
