ISO % question for extraction

Afaik it’s usually 95% etoh and 5% either hexane or heptane

This is the stuff I was thinking about, though it also has methanol which may make it a no go as well.

Wtf is QWERT by the way? You mean QWISO?

Like @Cheebachiefextracts said though just go grab some high proof liquor from the store. Everclear is all I used for years when I was younger b4 I could source ethanol

Do multiple dunks in the same volume of alcohol and for bonus points do it as cold as possible

Another option is making your ethanol?
Sugar + yeast + water + time = low proof alcohol
Create a cheap still with copper pipes to increase ur proof.
For the last steps, use molecular sieve to increase ur proof even more.

5 gal batch of low proof alcohol can be made every 2 weeks.
Copper still can be reused over and over.
Molecular sieves just need to be dried in an oven to be reused.

They meant QWET, quick wash ethanol extraction, as opposed to quick wash isopropyl extraction (QWISO)

The tools required to recover ethanol also give you the ability to MAKE ethanol.

So stop wasting solvent, and save yourself some money…

Hrs of reading around here on solvent recovery.

Eg: Who is king of EToH Recovery?

Tired of using a rice cooker to blow solvent to atmosphere, you can use that same rice cooker to power a still…

I actually do have a heating/stir mantle, skincare machine which i repurposed the medical vacuum pump off of, (no gauge so can’t tell what’s happening, it’s open loop light vac), and a basic distillation gear, everything here basically: https://www.amazon.com/gp/product/B07N2P9SKK/ref=ppx_yo_dt_b_asin_image_o09_s00?ie=UTF8&th=1

If I was gonna use denatured eth I would just get 195% without the nasty cutting agents and either use 195 or denature myself via my 3a molecular sieves.
I ALSO have 1lb of potassium carbonate I could use to salt eth from miscible solutions.
But yes, ethanol of any grade is extrememly expensive. Even sourcing cheap booze from the store and reducing it myself isn’t even 1/10th as cost effective as just iso(any grade) would be… =( Maybe one day I’ll be able to afford to step up to eth and be able to recover as much as possible.
@cyclopath I need to get a vaccuum gauge so I can see how much I could potentially recover with my current setup above…
Even tho everyone says distillation vs rotovap for eth recovery is taboo. (which I get, but hey, can’t all have a roto. Tho i will have a homemade one some day soonish)

I tried. Fairly certain I failed. Should have DEFF finished my homemade hydrometer before distilling all that waste to.loool(I’m gonna try salting it soon with pot carbonate and let you know if I even got anything, since my hydrometer won’t be done for weeks lol)
I maybe feeling brave and confident enough to try a rough determination by weight.
Which I deff should have did ahead of time. But eh… Live an learn?

Jeeze mane that’s super generous ty I’ll shoot you a PM

Why? Please elaborate.

I’m having trouble understanding to. It’s more polar. And strips more compounds.
So you’ll get things you don’t want like waxes and choloro, it tends to make a more dark product and less flavorful one because of this.
But in my head, I’m just be eating it in confections so I dun really care about it’s taste and look just the relief it will provide.
It’s just general accepted the selectivity of ethanol pulls a “cleaner” more tasteful product that the majority of people prefer.
With BPS of iso/eth at 78.37 °C and 82.6 °C should be really easy to separate out either one, tho in that context ISO is usually cut with some BS to make it 99%, but i just salt 70% to make my own 99% or high 90% with no nasty cutting agent. That and I’ve heard because ISO is more polar it bonds harder with water making it harder to seperate but that didn’t make much sense to me because it’s BP is lower even then eth which means it should be even easier to turn into a vapor. ISO is more toxic then eth if consumed but again. That should not be a worry if you are purging at correct temps and montionring what you put in/recover

I feel like you’re needlessly overcomplicating things. Just get the highest proof everclear you can source, and recover what you use. If you have the equipment already, this is a no brainer to me. I wouldn’t waste my time trying to separate denatured alcohol or whatever you’re trying to do.

If I needed to extract at home, that’s what I’d do.

Buy everclear.

Put in freezer.

Dump over cannabis.

Recover as appropriate.

This might be worth a read if you want to use iso.

Regarding water content, we did a bunch of research on ethanol extraction many moons ago that showed that having a water fraction in the solvent was actually beneficial. I wouldn’t be surprised if iso turned out the same.

Don’t over-think it, just do the thing.

Can you elaborate on the water fraction being beneficial? This is good stuff

Thanks so much for the info both yall. @terplord420 <3 I will check this all out after work today and report back. Maybe my local store has some super cheap booze… But even then it’s gonna be about 15/l min I already know… When compared to 2 bucks for the same amount of iso… But yeah. I guess it’ll be worth it especially if I can recover it efficiently.
I also heard the same thing. That people were trying to extract with denature eth then realized having 5-10% h20 content produced a better product anyway. Thus making the process alot easier and removing the strain of having to sieve your solution or w.e every-time after using. I will deff give that a read tho for the further details.

I’d have to go back and re-read the lab notes and report. This would have been done in 2018 or 2019, back when we were developing spray wash ethanol extraction methods and protocols.

Off the top of my head I seem to remember that 120 proof was a reasonably optimum point in the context of room temperature extraction. Maybe -20°C as well.

I believe it helped mitigate undesireable pickup. Considering we’re now two solvent systems away from our ethanol days I might get around to open sourcing that info at some point.

Thanks @Lincoln20XX . I would think that any water present would pull tons of water soluables. If you get around to it let me know

That’s incredibly interesting, I would love to get my hands on that data. I second w/ @Miles-Beyond if you ever get around to it please post an tag me =D

Look up some of @Beaker posts. They’ll have plenty of info for this

Righteous my mane. TY for suggesting. I will for sure do that =)
