puryifying oil?

[relic1981]

i was given about half an oz of shatter from a neighbor but it is a really dark color and dosnt taste all that great. its not horrible just not what im used to. i usually use real clean wax or shatter that i make myself or am gifted. so back to this other stuff, my friend said it was about 5 yers old and was butane extracted. my question is first of all why is it so dark if it was butane extracted and 2nd and probably more important, is there an easy way to clean up the oil? i disolved a small amount in 99% rubbing alcohol and then filtered it through 2 coffee filters. it cleaned it up some but very little was caught by the filters and it came out still very dark and not tasting too great. (i want to emphasize its not horrible or anything its just not what im used to and could be a whole lot cleaner) does anyone know how to purify it so it yields a golden oil instead of the dark brown blackish color it is. i have heard loose carbon will help but i dont have any loose carbon hanging around (except for whats in my carbon fileter) and im hoping for an easier method because the carbon method seems like it would messy. i have plenty of it to mess around with so any suggestions are appreciated. i ideally would like to take it to a nice amber/ golden color, even if i lose some of it.. i want it to be as pure as possible, after all it was free and i would like to make this a learning experience. thanks everyone!

thanks, i have however already read that article. i actually posted a link to a different article from that site in a different thread. i really like skunk pharm research, but thank you very much! this is what my back up plan is but i was wondering if anyone had a more simply way to do it. (not that the info on that page is all that complicated... )

peace

Color is due to age and or processing techniques, such as using propane as a solvent and purging with minimal heat to achieve a lighter color.

You were on the right track with the iso wash, although I recommend replacing the iso with ethanol and chilling the solution prior to filtering. You said it remained very dark and didn't taste that great after the wash, it was likely blown with sub par material. And being 5 years old, expect a very dark color! Best of luck.

 

[relic1981]

so you are saying oxidization has a role in the dark color? that would make sense. even if it stays a darker color i would still like to clean it up some so it isnt so harsh. and again its not horrible , just not what i would consider medicinal quality... yet im bound and determined to figure this out and yield some decent oilf from this old stuff. it was free so it gives me a chance to play mad chemist! lol i think i will try your recommendation on a little bit of it (say 2 grams) and see what that produces. thanks!

Polar elements tend to have more color, and hanging oxygen atoms to molecules as a function of oxidation, makes them polar, and tends to darken them.

On five year old oil, your best bet would probably be to redissolve it in a non polar solvent like Pentane or Hexane and run it through a chromatography column.

Here is a dark extraction that was fractionated using that technique, showing the different colored fractions as they were removed. The dark jars at the end, have virtually no cannabinoids remaining in them.

thanks gw. is that something i can build at home or do i need to find a chemist supply store most likely on the web. i used the info in this article by you.. at least i think its the same graywolf. http://skunkpharmresearch.com/getting-the-green-and-waxes-out-afterwards/ . i did winterize the solution ( i redisolved a few grams in 99% iso and then put it in the fridge over night and when i filtered it i was able to catch alot more waxes, etc than compared to just redisolving it and filtering, which dosnt catch hardly anything.. i also took your advise and put the solution out in the sun for about an hour to help eliminate chlorophyll. 4 hours seems a bit risky because i didnt want to lose any thc to degradation. its still in solution now, but is in a pyrex dish evaporating the alchol. it still loook pretty dark and has kinda of a green smell but not nearly as much as the original shatter i was given. the oil will still turn out dark, judging from what the solution looks like now. ive never used hexane before... where can you buy some? hardware stores? or on the web? one last question for ya. where do u get those super low micron filters forr syringes? do you think its is a lower micron than coffee filters? my goal is to turn this dark, ehh, oil into some nice amber shatter. or at the very least clean it up some more and remove all the chlorophyll or as much as i can.

 

[relic1981]

weird, it's hard to believe nobody has encountered oil they have wanted cleaned up. this seems like it should be simply but then again im no chemist, but i do have a good head on my shoulders and most of the time i can learn and lock down consepts easily.

so like i said i disolved about an eighth of this old shatter and winterized it after also letting it sit in the sun for an hour (hoping to break down any chlorophyll. (greywolf reccomends 4 hours but i didnt feel comfortable with it in the sun that long.) so the oil did get cleaned up some but not nearly as much as i had hoped. im thinking of redisolving the amount i originally disolved with hexane and then add water to that mix to pull any chlorophyll out of the solution and then seperate the two and dry the hexan extract.

will this work?

From the top, ethanol works better than iso for winterizing, and I’ve had the best luck in the freezer at 0F for 48 hours, vis a vis the fridge overnight.

One hour in the sun sounds short. Did you see any improvement? It works better in thinner films, so that the light can penetrate.

We get HPLC grade Pentane and Hexane from American Scientific, here in Portland.

They can also supply you with 0.2 micron syringe filters, or you can find them on e-bay.

Coffee filters are about 15/25 microns, while the syringe filter is less than a micron.

Chlorophyll is not really water soluble, but is highly soluble in alcohol. You might try mixing the alcohol solution and hexane in equal portions, adding a third portion of brine, and bleeding off the alcohol/water/chlorophyll.

 

[relic1981]

interesting, thanks gw... no i didnt see much improvement from the one hour in the sun. i saw that you recomended 4 hours but i was just playing it safe. i think im going to go with your above mentioned technique. so after re disolving it hexane, an equal amount of ethanol will percipitate some or most of the chlorophyll out? then i just bleed that layer off, get like a 12cc syringe and pull it through a 2micron filter and then purge it? oversimplified i know but is that what you would recommend or am i wasting my time here. i know im not going to be able to turn 5 y/o chlorophyll contaminated shatter into any award winning oil or even close im just trying to clean it up enough to take a dab from it. right now i wont run it through my piece because i dont want to mess up the flavor of my other extracts. thats what made me want to purify it, the flavor sux. and i also realize that its 5 y/o so most of the terps are gone (the good ones anyhow) so im not expecting a miracle. i hate to waste things but that includes my time as well. thanks again for the help. i would like to get it to a state (of matter) where it will be good to have on hand for a rainy day.

 

[relic1981]

ok, so im still working on sourcing the hexane but i was able to find syringe filters but they are.22ug (microns) is that going to be too small? i have a feeling it will get clogged easiyl. just to be clear... i want to pull it through the filter while its still in the hexane solution (i dont think it would pass through it if its not in solution) so where can i find hexane or a similar ideal solvent? i dont think butane would be a good choice because it evaporates so fast and in a container there is alot of pressure that builds up. please correct me if im wrong.
thanks everyone!

Didn't see availability of Pentane at ebay without a ship to business address, but Hexane's up, and so is low boiling point petroleum ether (60-80C.)

"Petroleum ether is a mixture of alkanes, e.g., pentane, hexane, and heptane..."

"Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter naphtha and the heavier kerosene. It has a specific gravity of between 0.6 and 0.8 depending on its composition. The following distillation fractions of petroleum ether are commonly available: 30 to 40 °C, 40 to 60 °C, 60 to 80 °C, 80 to 100 °C, 80 to 120 °C and sometimes 100 to 120 °C. The 60 to 80 °C fraction is often used as a replacement for hexane. Petroleum ether is mostly used by pharmaceutical companies and in the manufacturing process. Petroleum ether consists mainly of pentane, and is sometimes used instead of pentane due to its lower cost.[1]"

I bought 60-80C pet ether from these guys several months ago, NP.

cool thanks for that info!

A widely sold aerosol electronic cleaner is a C6 petroleum ether, propellant, and a little ethanol that can be washed out with water. A pure heptane brand of solvent is sold at arts&crafts stores.

personally man. i just made a hexane hash oil.. and a butane hash oil.. the hexane hash oil is a lil darker.. and is harder to remove that hexane smell.. even in a thin film in the vac chamber.. looks like i might decarb the hexane oil to make sure its fully purged.. then add it to capsules.

 

[relic1981]

i was thinking about making this into rso type oil or fully decarb it and out it in capsuls for orall use. how much do u add to your capsules?

 

[grow nerd]

Chances are, it'll be more work and more costly to wash the stuff only to end up with stuff that's still not very good, than obtaining better concentrates or fresher material and making it yourself. Most if not all of the terpenes are likely gone, too.

 

[JointOperation]

how much u add to the caps is tolerance dependent.. we decarb.. and fill them to the top.. and pop 1.. and be rocked all day. if its good potent oil!!..

but that took experimenting with doses to find the best dose for me... the best dose for me.. may be way tooo much for you.. an edibles arent something you wana take wayyy to much of.

 

[relic1981]

thats the thing it is super potent still. i think ill end up making capsules out of them or make it into simpson type oil. like someone said, it is alot of work, time and money to dissolve it and then repurge it and end up with oil that is still dark and runny.

side note question, what do you guys do with your reclaim oil after cleaning your oild rigs. im trying to make shatter out of about 5 grams of reclaim but its just not holding its form and returns baack to liquidish oil. messy i hope someone has a good answer for me on that too.
thanks everyone

I rinse mine out with hot water then alcohol, down the drain.
