    this may just be the science geek in me but i was thinking about trying to purify using a distilation process such as one used in a chem. lab. i think you would disslove the thc in some solution, an ethanol or something like that then boiling up and condensing in another container...any thoughts or imput on where to do something ike this

    Try it brother, never hurts to experiment. It sounds viable, seeing that's a similar process to making canna-oil for cooking and such,

    You could have made up your own distilator?

    I believe it will work.... as I recall it has a section on distillation for making honey oil in my grow book. I'll check it later and put up what it says.

    nice, anyone able to find any links to something like this

    Haven't looked, but I will

    Do you have any experience of making good distillation?

    Whoa, the science here is questionable at best.

    The boiling point of THC is about 392 degrees fahrenheit (200C).

    The boiling point of ethanol is 173 degrees fahrenheit (78C).

    By distilling that solution, you would only be distilling the ethanol, and getting pure(r) ethanol. All the leftovers would contain the THC. So really, unless you are really concerned about conserving your stash of easy-to-obtain ethanol (most likely a high-proof rum, or everclear) all you want is to evaporate it, so you really don't need to worry too much about distillation equipment or techniques.

    Just leave your shit out, and keep it from flames. Distillation would be silly. If you are trying to get it all out and make something smokable, you should use something besides ethanol though. It is difficult to obtain pure ethanol, and the remaining bits will be slow-evaporating water weight. Try using something that is equally volatile, but is easy to find in a pure form. Butane is probably a good bet. Just make sure to find unscented butane.

    What is better?

    kochab New Member

    butane all the way. hash oil with butane evaporates the unsmokables MUCH MUCH quicker than ethanol

    I, infact have thought of this and one way that i can think of is to boil the THC using a vaporiser of some sort and condensing the vapor in tubing using either cold water or any other cold solution. You would have to find a way to get the condensed solid out of the tubing, but that would be easy enough using a rubber plunger of slightly smaller size than that of the tubing. It will also contain other cannabinoids, but will get the job done. Using butane is effective too.

    Hey, This is no problem. You are going to need a couple of things. First go to 7-11 and get one of those metal straws, any copper or stainless will work but the straws are only $1 so they are cheap. Then go to the local hardware store and get either RONSON butane (only this brand as others have additives to prevent this, and definatly not camping butane as that will KILL you.) or the local Acetone, alcohol will also work if you have a retort and such. You will also need a PYREX measuring cup. (pyrex cuz it can stand the heat better and is nearly unbreakable.) Then large screen from your local smoke shop and a fitting to hold the screen on one end of the piping. Then take the cap off a soda bottle and use a small kitchen knife to make a hole just big enough for the end of the butane can to fit through. Fill the tube with your marj. (Schwag) and run the butane through it into the pyrex container. Two or three cans is enough for 1/2 oz. AS far as alcohol or acetone, you can simply use it as you would any other distillate place in, heat, collect, replace and do this about 4 times to get the best result. Keep it liquid by keep adding acetone or alcohol until the last time. Then simply let it bouil itself out, you will end up with a dark green/ black gooey substance. Add a little of your chosen solvent (1/4 oz. per oz of starting product) and use a small paintbrush to paint it on your cigs or the inside of your pipe. Alternatively you can take all of the goo and add 1/2 oz of solvent per oz of product, dump all of your weed in and mix it up really well while puting your pyrex container in just barely boiling water untill it all evaporates.

    You want to use 4x or even better 5x refined butane ronson will leave a nasty residue in the oil.

    I'm getting ready to distill some cannabis oil extracted with methanol the only thing that has me worried is chlorophyl's boiling point is listed as decomp. so I'm not sure whats gonna happen when I apply the vacuum if the chlorophyl will decomp still and leave a smoke residue in the distilled resin or worse if the chlorophyl comes over intact at the same temp as the cannaboids. hopefully it just remains in the first flask.

    Anyone done this before? at what condenser temp does the thc begin to clog the condenser?

    Im actually trying to do the same thing with some minor differences. I plan to perform an exration with anhydrous ethanol. I will distill off the ethanol on the first pass. Then using a fractional column I will vacuum distill off thc. What do think?
