    Not that I'm aware of and I've been monitoring this forum for quite some time.

    any reason you can think of that nobody has tried it? is butane a particularly nasty chemical or leave hazardous traces in the extraction?

    Are you trying to extract flavour or nicotine? Have you worked with butane before? It is MUCH MUCH MUCH more volatile then ethanol.
    Please be safe.

    I believe it is mainly a question of where the desired extractee is located in/on ones extraction material. In tobacco, the desireables are the leaves themselves and (mostly?) anything in them. In other materials, the desireables may or may not be found in soluble form on the outside of the material.

    In other words - what is considered waste product - the plant itself - from the latter process is what you ask how to "butane" anything out of.

    My best guess would be because there are many less volatile solvents available that are fit/safe for human consumption and don't require specialized apparatus (pressure vessel) for the extraction process. Most members on this forum are hobbyist and lack the expertise required for using more exotic solvents/equipment/processes. Butane is a gas when not under pressure so the extraction process would require using a pressure vessel of sorts. I'm unsure if Butane would deposit (leave behind), any harmful/toxic residue but being a petroleum product (like Hexane), I'm relatively certain it's mildly toxic to humans. There are several extraction solvents I haven't used because they need to be completely removed/neutralized after the extraction process is complete. Denatured ethanol, isopropyl alcohol and Hexane are some examples.

    Apparently mixing the butane extract with PGA will get rid of impurities,and then you evaporate the PGA out and tranfer it to PG.

    although using the heat to evaporate the pga may defeat the whole purpose.
