Apparently rosin is chemically extracted

do our back and fourths sound like it was written by a computer?

No, I am very creative :robot:

Hey, I love “solventless” cannabis extracts as much as the next guy, buttttt…

Why is it that a self-proclaimed hash “guru” (The dude is all over IG, posting all the heady BS next to the mothership he spent 10k on)… and it takes 6 days to extract 100lbs of fresh frozen bio, gets me a 2% yield of some B grade rosin (got $7 a G wholesale), and the COA on the product is 71% potent, 6% terpenes…

Then I give 100 lbs of the EXACT SAME BIOMASS to a Hydrocarbon Tech that I personally trained, and I know has >60 days of experience total is his life… It takes him 4 hours to extract all of it, ready for testing in 3 days total, gets me a 3.8% yield of some A grade (Got $8 a G wholesale), COA’s show me 85% potent, 8% terpenes, 9 ppm of residual N-butane…

Because stereochemistry doesn’t give a fuck if you’re a heady-boy with clout on IG. That’s why.

Stereochemistry?

How exactly is stereochemistry relevant here?!?

You reckon there is something sinister about squish

I do a “little” consulting for a HTL (hydro-thermal liquefaction) group. They are into the synthetic jet fuels….but your statement
“From seawater” is off target…I think you may be confusing some steps….perhaps “with seawater”? You need a carbon, C, source.
Please inform…if you have reference …perhaps I don’t understand what you mean.
Curious…and way off topic. Dm if you like.
Regards

Thanks

There is a lot of information out there about it but here is some.

Yes, I see we have our carbon source…

Nice reference….
Thanks for the further explanation.

Not in the slightest. I am merely suggesting that chemically selective solvents with tightly controlled temperature parameters might have an edge when it comes to extracting compounds of interest, relative to chemically nonselective methods like agitating the biomass in ice water and attempting mechanical separation with a hydraulic press and a sieve bag. That’s all I’m saying. No shade on the squish.

Not shade. Asking for any reason for bringing stereochemistry into the discussion.

Other than not knowing ones Rectus from ones Sinister

Very few of the solvents used for extraction have anything in the way of “stereochemistry”… can you name an exception?

Hint: it’s also one of the few exceptions to “plants generally only produce one stereoisomer…”

Yes, there IS stereochemistry at the heart of our precious cannabinoids…I’m asking how chirality is relevant to the extraction process.

Yes! And when you combine this with ALL the detailed knowledge of BUTANE EXTRACTION THEORY…
Why not throw out “chirality” with the rest of the BS.

It’s all water over the dam now.

With considerable amusement.

Exactly!

If we were synthesizing from scratch, then using chiral solvents would make sense.

Solvent structure is a variable to consider

The chirality of several terpene isolates produces highly variable results when used as a secondary solvent for post-processing/refinement techniques.

Additionally, not that it is directly related to the question of stereochemical conformation, but different hydrocarbon isomers also function extremely well, or rather poorly, depending on the parameters at which you attempt to use them for extraction, Iso-butane vs N-butane is one obvious example.

I have been conducting a large-scale research project in my lab, for instance, to test the efficacy of various hydrocarbon solvents at a wide range of parameters for the extraction of specific cannabinoids, terpenes, thiols etc.

To date, we have committed over 50,000lbs of fresh frozen biomass to this endeavor, with some exciting results and some very clear winning formulas. Keep your eyes peeled for a white paper to be coming soon.

I guess a better way to put it than I did in my initial ramblings, would be to say that “Chemoselectivity doesn’t care if you’re a heady-boy with clout on IG.” But I digress.

I am making fun of first step extraction.
If you think the whole class of modified cellulose supports

Now back to rosin: chemically extracted…?

Suggesting squish is more “full spectrum”?

One would expect the changing the solvent to change the nature of the extract. How many PAIRS of terpene isolates have you compared.

Limonene is the only one I can think of off the top of my head, but I certainly imagine there are others.

“Highly variable results” could be construed as a failure. One generally aims for repeatable differences

You are aware of the enormous amount of effort put forth in the past two years concerning “chemoselectivity” of solvents, especially alkanes in the extraction of cannabinoic acids AND their subsequent precipitation in various crystalline forms.
The fact that you are even here offering information means that your have found an audience which is capable of appreciating your 50K lb efforts in VARIATION. So in regards to “chemoselectivity” as a broad term, you are preaching to the choir.
Now with respects to chiral chemistry?

But a priori , please tell us what it is you are extracting from
Biomass. Like a little molecular diagram…or what it is YOU THINK you are extracting into your chemoselective solvent or chiral terpene modified solvent.
Or better, perhaps a white paper on the state of cannabinoic acids in trichome storage soup?

Or better, save everyone a lot of time…and explain the crystal structure of medusa vs chalk.

If you read the X-ray diffraction study on THCA….they produce a crystal product ready for diffraction study in a single step…
Using a procedure that has less than 10% efficiency ….now that may have something you might write a white paper on.

Actually , it is obvious you know what your are doing…looking forward to your white paper reports…

Have you given much thought to water? Might want to get away from those nasty, carcinogenic terpenes…

Sometimes there a bit of humor here.

I should add, it is quite clear you have switched from “stereochemistry” to the more broad caveat, “chemoselectivity.”
