Recovering lots of B/PHO oil extract from jars/containers

So I saw the post on Whats the best way to get thick crude out of jar and into boiling flask ? about this. And have read multiple other things about the process. They all see the same. But this is weird to me. Because no amount of heating or pouring gets nearly all the product out? At least for me? What solvents would be best to soak the jars in to try and recover all product in solution, consolidate said solutions, then re-purge without damaging/loss of product and make yummy infused edibles? =)
I’d guess probably DCM or high proof ethanol/ ethyl alcohol / anhydrous ethanol or isopropyl or something? Be preferable to be able to just recover everything into one pot and then be-able to just heat off the solvent used as I no longer have access to vacuum or inert environments.

I prefer acetone to clean with then just filter/recover/distill from there…

To boot it does a room temp dewax on whatever is there so just filter before recovering solvent. :wink:

I do like the BP of acetone. =X AND the sound of room temp dewaxing. For some reason I always avoided it in my extractions? but it’s been so long since I been in a lab I can’t really remember why? Toxicity? Unfamiliarity? Psychosomatic? lol.
Could I trouble you to elaborate just a bit more on the process/tek for that?
Appreciate ya much bud. :hugs:

If you grow diamonds from it they typically test below ppm threshold or non-detect from what I have been told. Basically no different than pentane pyrex tech. The rocks are large and it’s a room temp process. Takes about a month to grow.

If you make disty then the solvent should be gone no matter what. Fastest way to run is first pass hot, acetone dewax, second pass and your done same day.

Technically speaking, you make small amounts of acetone in your body as a natural byproduct of breaking down fat.

I’m in the heat and ethanol camp. Heat the jar with crude to make it pour then throw it in a bucket of ethanol. Once a week recover the ethanol and you have more crude.

Would filling the jars with ethanol(what proof/kine do you recommend?) be enough to loose everything with no scrubbing or heating? Then I can just pour off into RBF for re distillation/solvent recapture?
Would you happen to know the pros and cons vs. ethanol or acetone? (for you too, @Zack_illuminated )
Am I gonna loose product or have any molecule conversions?(I’m more worried about degradation of original distillate into non psychoactive byproducts)

you might need heat if it’s a lot, the residue from a jar will dissolve into high proof ethanol pretty readily at room temp

you shouldn’t have any conversions if you didn’t use acidic media/acid at some point and don’t get any major vacuum leaks/crazy temps

Awesome, that’s exactly what I was thinking to. YOU wouldn’t happen to know to pros and cons of acetone vs. ethanol for this, would you? ;p Thanks mte

Pretty sure ethanol can degrade the product the longer it is in it due to the -OH bond. Have heard tell of potency losses from resting in ethanol for long periods. Chemically both solvents can form byproducts under acidic and basic conditions.


For acetone:
Under acidic conditions, aldol condensations, hydration, and halogenation are possible.

Under basic conditions, aldol condensations, enolate formation, ketonization, and Michael additions are possible


For ethanol:
Under acidic conditions, esterfication, dehydration, and oxidation.

Under basic conditions, dehydrohalogenation, oxidation, and saponification.

Dang that’s some wisdom right there.
So excuse these newbie questions bud, deff not on your level yet…
But what would cause one condition or another? I’d probably have to make the condition either acidic or basic by my own addition of substance? Or do I need to worry about my solvents becoming to acidic or basic once they adsorb the product? Or from source? You have max storage times in these solvents before worry of negative effects? I probably wouldn’t store it more then a day or two or prob even same day before going into re-distillation/solvent recovery…

Ethanol is a weakly acidic compound, possessing a hydroxyl group (OH). In theory, it can act as an acid and donate a proton (H+) to a base, or as we have seen with cannabinoids, acidic conditions can lead to oxidation (red color on top of disty jars).

CRC can create such conditions depending on the media used. Technically speaking, acidic conditions also help with acidic molecule crystalization but can lead to faster degradation.

If you were to tritrate neutral cannabinoids in ethanol with acid, it will make it all red. If you retritrate with base to neutral it will return to the typical golden - tan from red. But too basic and it can start becoming red/purple again.

Basic environment with acidic cannabinoids and you will convert the acids to water soluble salts, which are the conjugate base of the acidic molecule.

I suggest you start by looking up the MSDS for both…

We use ethanol.
We pump it fast enough through that spray head that it gets warm. Gets the majority of the cannabinoids in just a few min.

No way in hell I’d play this trick with acetone…

…and we don’t make “dish-dillate” from it because those containers were all marked with sharpies, and we don’t need extract of pen in our pens.

I think it’s time to change drop the sharpie from the SOP…

We have discussed that.

Especially now that OR has given us processing jobs (which can be used as “accumulators”).

Haven’t solved the labeling issue. I want barcodes etched on everything, but that won’t fly.

We still use sharpies, but I complain and want the writing on painters tape that is easier to remove. I have spent way to many hours removing writing and sticker residue before soaking dishes in ethanol. I better get to work, today I make hot dog water aka dishtillate.

I’ll probably just be doing some beamtests tbh =p Tho I do love a nicely CRCed product.

Very interesting. Wouldn’t that be a good thing, short term? What does acetone do?
Do you recommend me doing PH tests on the solvent after extraction to make sure it stays within a certain range? Or if I distill quick enough would it prob be a pretty much non factor?

Ok not to be a kiss ass but you are clearly like god chemist level over here. lol. Thank you for the input. I am not gonna lie tho I’m having a lil bit of trouble fully understanding that? Do I want a basic or acidic environment? Do i want only acidic cannabinoids? Do i want to convert to salts? Conjugate base of the acidic molecule… Hence, a conjugate base is a substance formed by the removal of a proton from an acid, as it can gain a hydrogen ion in the reverse reaction. Because some acids can give multiple protons, the conjugate base of an acid may itself be acidic.? I’m sorry I really appreciate your patience and explanations. Rock on mate

An sorry in advance everyone forum is throttling me and making it really hard to stay engaged/keep my place or train of thought…

Is is ONLY because of what ya’ll use to mark stuff or other reasons to? Thanks for the info bud.
Also fk metrc and the gov. Sorry you have to deal with all that. I got tired of running a lab for a slave wage of 25/hr. Hope your’re making out better in this industry then most my poor fellow workers I talk to. This industry needs a strong union.
Keep up the good work

Have your read the msds’s?!?

Stuck your snoz in a bottle of acetone?

You can drink ethanol…try that with acetone and report back.

Edit: please don’t, it would most likely kill you…
