I git the general feelin it wouldn't work as envisioned, but I don't know enough to answer properly...lil help?
There was a guy on several other forums that was experimenting with removing the valve from a a CO2 tank and filling it with plant material and dry ice, before replacing the valve and heating the tank to super critical pressures. He then inverted the tank and blew the liquid out of the tank into another container, which the oil condensed in. He got banned from multiple forums for spamming, and I haven't heard from him in awhile.

The technique produced oil, but it is unknown what the quality was compared to our own BHO. I am convinced that it is every bit that easy to achieve SCFE pressures and temperatures, but the trait that sets SCFE above the rest, is its selectivity. Running the material through the entire temperature and pressure curve, would not be a selective extraction and so a process would have to be developed, which produced the desired end product.
...will update with any new posts that come in.:)

basically, after reading butanes msds, hes convinced its not at all harmful or toxic AND that there is a TON of improperly purged BHO out there these days...

I did an analysis once...tried to show an accumulation of impurities from butane in a years worth of dabbin. It din't exist...that shit's pure, pure, pure. Lightin a day's worth of cigarettes with a butane lighter, is far more unhealthy than a years worth of dabbin. :p

but the butane you get from using a lighter has combusted and at that temperature,
has consumed alot of the contaminants in it...

not true of butane used in this fashion.

im with that one guy in realizing that all those threads and valves and hookups and machines that put the lids on use all manner of lubricants and no matter thats its trace. its still in there. not to mention butane, even 5x and 7x, is a blended glass if your not buying n.

nbutane,
medical grade

[ probably shouldnt give an stoners the idea there is something worthwild in putting dry ice in a closed container... might wake a few of em up enough to do something stupid ]

For the record, I have never been banned for spamming, though I have been banned for trolling and this is just one of those funny little coincidences that points to the possibilty of a God with a sense of humor.

Not true, much of the butane remains unburied....as with any combustion process.

im not aware of a single extracted specimen containing no traces of .... (insert your chemical of choice)

also ive never seen co2 extracted "oil" - all oils which were titeled as co2 were in fact bho,iso .. whatever ...

imho co2 "oil" is logical nice marketing trick / move ... selling more bullshit for even more money - reminds me of the time in the 80s when moldy hash was a "special treat" in the coffeeshops and was sold for twice the money and all were buying it like crayz .....

stupid mankind

awoken the right way

I love bubble but you can't make bubble out of crap.
I couldn't give a fiddlers fart about marketing.
I am only interested in giving myself the cleanest possible product and I think I received all the encouragement I needed via Bob to go ahead and build a prototype and see what comes out of it.
Thanks for all the opinions though.

Eh, it's bein played around with. The biggest drawback is that the equipment to do the extraction correctly & safely is really fukkin expensive...so to make it a worth while investment, ya gotta pump out a buttload of product. These extractors are used in other industries, but the canna industry is not yet big enough fer them to be cost effective. It'll come, eventually.
