Haha nope, now you see why I don’t like to use pentane for LLE, it just evaporates into thin air. You lose pentane very quickly

It was fluctuating between 32c and 40c. Water was alittle cooler upon adding. As to not evaporate as much of the tane. Everything was good, I thought I needed a neutral pH wash so I was going to make that my last wash and it ruined it. It’s like it made the tane mix with the water which is not normal in my experience, generally polar and non-polar do not mix, they separate. This mix had a very hard time separating
Boiling point of Pentane is 36c…
It’s in the air.
You gotta keep it like 25-30c below the bp, and preferably in a closed/pressurized vessel. It evaporates readily with it’s high vapor pressure.
Also… I super duper hope it was nowhere near an igntion source… Air full of alkanes is no good, make sure you have proper ventilation and temperature control on that setup.

Yep it evaporated
It go s realy fast if the surface area is
Is like 5" diameter

I know how to work in a lab man. Of course I have ventilation, and I was doing this in a 20L batch reactor with an exhaust line into an iced jar because I knew it was evaporating, I can see the vapors, I know how solvents work. I have extensive experience with hydrocarbon gasses.
I am having an issue with water and pentane doing weird shit,
Safety is not an issue for me, thank you for your concern though.
Now I realize my pentane went away and I was left with nasty hash water, thank you for the help.

Anybody ever made some fire ice water hash and then smelled the water like “fuck that smells good” …?
Maybe a simple LLE to pick up the terps? Keep under 0 c to reduce both off gassing water content. Mol sieve the final product to eliminate water maybe some crc type action…

Absorb all that bubblehash water into 3a mol sieve, then extract the mol sieve with propane.

Magnesium sulfate loves water

Did you extract in EtOH and if so, did you get rid of ALL the ethanol?
That will destroy the layer separation as it makes the aqueous layer way more open to pentane

I’ve learned this over the weekend. I was told I didn’t need to recover all the ethanol before, doing more research I found hexane is more suitable for what I’m trying to do. Guess it’s time to suit up!

How many stages was your LLE or maybe the better way for me to ask is how many times did you have to do this? Can you share a picture of your LLE setup?
A poster postulates that ether is particularly good to grab water soluble terps from water. (Which seems like a better choice anyway for lle except it needs to be dried after extraction and distilled before use).
I have also a litle question, hopefully someone would like to answer:
Whilst performing a wash, is there a danger that under particular circumstances thca or cbda could migrate to the water? We all know it does at very basic ph with NaOH but could it also happen otherwise with certain acids or bases?
If you don’t use enough solvent you’ll get an emulsion layer that is tough to get back into solution which could potentially cause yield loss if you drain out the emulsion layer but otherwise, not really. Water and non polar compounds stay separated really well, hence why LLE works.
You’re using your non polar solution (pentane and extract) and using the water to extract any water soluble compounds that are present.

Thanks dude, I was just asking because you never know. Maybe there are certain acids at specific ph’s that make somthing new and cause cbda to go into emulsion with all of the water. Somewhere it said it is important to decarb before washing but didn’t give a reason so was just a little bit concerned.
That’s why you need in house analytics…
… and someone with some chemistry on your team.
there are certainly other bases besides NaOH one could use to get your cannabinoids into the h2o.
adding acid can have other consequences, but solubilizing your cannabinoids in water is not one of them.

hmmm ok so cannabinoids become a lot more water soluble at ph 11 and higher and ph 13.6 beefing the most water soluble ph
BUT when the cannabinoids are acidic the ph starts at around 8.3 ph
these are numbers based on water and noids no terpenes in the mix
at the same time the final PH water is crucial for it dictates the form your acidic cannabinoid is in cooh coo- etc etc and I would defiantly recommend looking up at @moronnabis his remarks and teachings

I love to use Ether for LLE in my etohs extraxtions of fresh frozen flowers.
The terps is insane…if i heat more than 60 celcius and cap the extract, a LOT of terps start to stick in the cap… a lot! Is the more flavor thing that i can smell and taste. And yes My teory i think was right, more types of terps migrate to the ether.
