Says crude cannabis extract has similar solubility to thc9...
View attachment 84742
Fixed Oils:
Idk what the solubility for cannibinoids in coconut oil, or olive oil is, but I'd assume it is similar to that of sesame oil which is listed at 0.3g per ml, or..
Known:
236ml per 1cup
Solve:
(236.58ml/cup) × (0.3g THC/ml oil)
=
70.974g/cup; 1 cup of sesame oil can take up to ~71g of extract, or
~71g of cannibinoids can fit into
1 cup of sesame oil, 72g of cannibinoids is 1g of cannibinoids too many, so 1g of cannibinoids won't dissolve into the sesame oil. If sesame oil is similar to coconut oil or EV olive oil, or margarine, butter, ect, then you probably don't want to try to dissolve more than 60g/cup to be in the safe side. We're assuming ~71g/cup is actual saturation, but Id shoot for no more than 60g/cup to be safe. That's for fixed oils ect. Alcohol is different.
Alcohol:
It says that ethanol (everclear) can take over 1g of cannibinoids per ml, but I'd just assume 1:1 like it also says. This means you can add 3x as much cannibinoids to ethanol before it's saturated compared to a fixed oil.
(236.58ml/cup) × (1g THC/1ml ETOH)
=
236.58g/cup ETOH;
8.3oz of cannibinoids (not 8.3oz of bud, 8.3oz of cannibinoids), before
1 cup of ethanol is finally saturated with cannibinoids.
Some thoughts:
Ethanol (ETOH), evaporates in the oven when you bake so the only thing left behind are the cannibinoids. Fixed oils obviously stick around during baking, but are good options imo as well. If you want a potent end product then you'd want to use ethanol because it can handle so many more cannibinoids before it becomes saturated.
What this means for solvent based concentration:
If you're ever wondering how much solvent is needed to fully dissolve the cannibinoids from your material, then this info is exactly what you need.
How much everclear:
Everclear is typically 190 proof, or 95% of the volume is ethanol and 5% is water. So in 1 cup of ethanol there's...
(236.58ml ETOH/cup) × (0.95)
=
224.75ml ETOH per cup of 190 proof everclear
Solubility of cannibinoids in ETOH is ~1g per 1ml, so
224.75g of cannibinoids (7.88oz) can fit inside 1 cup of 190 proof everclear (which happens to be equal to 224.75ml of ethanol and 11.83ml of H2O).
Estimate your potency...
Lets say you have
26% herb.
(224.75g cannibinoids/cup ETOH) × (1g bud/
0.26g cannibinoids)
=
864.42g bud/cup ETOH; cannibinoids from
1.89lbs of 26% bud would be needed to fully saturate
1 cup of 190 proof everclear with cannibinoids.
Obviously the rate of dissolution decreases as the saturation increases, and you'd obviously want to use more than 1 cup of everclear for almost 2lbs of bud, but dissolving 224g cannibinoids in 224ml ETOH is chemically possible.
How much oil:
Lets say you had 26% bud and using a fixed oil with a cannibinoid saturation of 0.3g cannibinoids per 1ml oil, or ~71g of cannibinoids per 1 cup of oil.
(71g cannibinoids/1 cup oil) × (1g bud/0.26g cannibinoids)
=
273g of 26% bud/cup oil; cannibinoids from
9.58oz of 26% bud can completely dissolve in
1 cup of oil resulting in a saturated oil. Typically heat is involved when it comes to extracting cannibinoids via oil (butter ect) so in this case think the decreasing dissolution rate is less significant because the added heat is going to speed up the process anyways. If you are just adding some pre-made shatter or wax or whatever, then you will be limited to 71g of wax per cup of oil.
Method suggestions:
Personally I'd just soak the frozen material in a frozen jar, use frozen everclear, and let it soak for a cpl min in the freezer. Then strain it in the freezer (takes hours sometimes due to low viscosity, but it will stay cold the whole time, while if strained outside the freezer the solution has time to warm and pic up undesirables as it filters).
This way you're keep your max possible cannibinoid saturation % low which means any cannibinoids present will want to readily dissolve (which helps when temps are so low), but also keeping everything cold so that most water solubles are left behind. You want to get everything set up inside your freezer before you add your ethanol to soak. I put my diced material in a jar and let it freeze, and then set up the strain station, and then finally add the ETOH to the frozen jar containing the frozen diced material. Then let it soak for a cpl min with a slight swirl of the jar at the beginning. I use beer coozies and/or winter gloves to transfer the liquid and pour the contents of the jar into the strainer station so that the heat from my hands doesn't warm the solution. I also try to transfer as fast as I can to the strain station so that not much warm air comes into contact and warms the solution. It takes a while to strain and if you added 20°f to your freezer when you opened the door and let all the room temp air in, it will take some time for the freezer to get back down to really cold temps, and during this time period your solution could be picking up all sort of undesireables from the increase in temp. Cold temps are crucial. Then just purge using your preferred method, or evaporate it till you get the desired concentration you're after and then (label it with the concentration is a good idea) store for later use in recipes.
Summary cause, "god dammit! That's way too long!":
You can fit the
cannibinoids from over a lbs worth of bud in 1 cup of everclear, and cannibinoids from over 0.5lbs of worth of bud in 1 cup of oil.
Also means you can fit ~
70g of shatter/wax/ect into 1 cup of oil, and
~236g of shatter/wax/ect into 1 cup of 190 proof everclear.
The less saturated the solution the more it wants to pull cannibinoids away from the plant and dissolve them into the solution, so when using alcohol use at least equal volume alcohol to volume of buds and you'll never have to worry about slow dissolving times, and never have to worry about not pulling all your cannibinoids from the buds. Though this is just personal preference as you can see above that you'll never be in worry of saturating your ethanol realistically, though it just may take more runs ect to fully pull the cannibinoids from the material. I like doing 1 run and getting all the stuff and calling it good.
Keep the alcohol extraction process cold!

Don't ever make BHO in a freezer. Don't ever soak buds with butane in a freezer. The above is talking about ethanol and everclear, NOT butane. Don't ever make or strain BHO in a freezer.
The vapors can ignite and explode. The amount of O2 and the different chemical properties that ethanol or isopropyl vapors have vs butane vapors makes these other substances much less worrisome, but butane vapors can ignite and explode and blow your fucking freezer door off or through your teeth/eyes/head when the fan kicks on and sparks, or when you open the door and the light bulb sparks, ect ect.
Never use butane in enclosed areas! The above method suggestions are for ethanol only.
