My Heptane extraction

[Chiefsmokingbud]

Well, recently was turned on to heptane from this forum so i had to try it. Bought a 500 ml bottle for approx $30 with shipping and no this is not a cheap alternative to butane, actually a good bit more but Heptane is derived from cotten seed oil, and environmentally safe.

I used 18.3g of Astroboy nugs and approx 250ml heptane in a mason jar.

Shook for 45 sec but a 30 sec soak will be fine. Strained it through a coffee filter and tried a warm water purge "outside". It evaportaes almost as fast as acetone but not as slow as Iso if that gives you an idea. Oh yeah the fumes are a mild sedative.........and yes i got a little light headed with no respirator so again do this "outside". I did it outside but somewhere inbetween i got some fumes.

Ended up with 2.5 g with is par with my yield with butane with this same strain. Although i do belive i had some what i call "transfer loss" from the coffee filters. next time i'll just strain it through stainless mesh. If you find yours still a bit runny, purge it some more. After the water bath and 2 hours on a heating pad set on low, it is almost as hard as my BHO with a decent color. If yours drips off the razor blade like my pic, purge it some more.

PS. had to edit the Heptane bottle for secutiry.

almost as hard but hows da flava?

Seems to be slightly smoother and sweeter than my BHO. Smells a bit like over ripe fruit which is what Astroboy smells like.

You did IT !!!!!!

Nice one...was waiting to see how it went !

perfect !

your the chief

srry...how was it ? read your exp. above but did it seem to get you higher then bho/iso? and do you think it was cleaner smoke ?

Enjoy the oil Chief

be careful. any saturated hydrocarbon is extremely dangerous to your health. all cause brain damage.

pet ether and all distillates included are extremely flammable. actually, ridiculously flammable would be a better description.

and, there are much more effective methods of extraction and purification of thc.


also, please!! buy a hi vac!

I can't say it was more potent but it did have more flavor and was just slightly smoother from what i could tell. Can't even say if oil from heptane is safer either without having it run through GCMS but atleast is can say i did it lol. Big question is would i give up using Butane for this.......absolutly not, the cost difference is night and day.

Heptane is a petroleum distillate. it can be found in many other places, but if you buy 500 ml from a chemical supplier, your buying a petroleum distillate, guaranteed.

thats fine, however.

if your going down the non-polar solvent route, try pentane. mw is high enough to be a liquid, but volatile enough that it will easily evaporate or boil.



also, another good solvent is dichloromethane. i know, chlorinated solvents sound scary, and dichloromethane has been proven to be carcinogenic. well guess what, so are all saturated hydrocarbons, and dichloromethane requires prolonged intense exposure to be carcinogenic in humans.

think of it this way, if you used to drink decaf, then you used to drink small amounts of dichloromethanae.



the upside? its not flammable!!!, and it has a low boiling point. it is not miscible with water, and i doubt if it is a watched chemical.

Nice job, haven't seen this done yet. Although since you experienced more flavor, maybe BHO gives you a slightly better, more pure product.
