Short Path Distillation

[Breakover]

In my limited experience, you can't get all the wax out in short path. Some? Yes. But even wiped film can't leave them all behind.

Lessss tawkkk abouttttt
....dewaxing before distillation?

I've heard claims as to dewaxing the oil not being necessary before going for clear. I've also seen those claims come with cloudy "clear." I bet you could fraction many if not all waxes off, but I infer it'd be a hell of a lot more efficient to remove them previous to short path, especially considering many extraction techniques used today (subzero hydrocarbons + ethanol). So I call bullshit on that.

But maybe, 48hrs at -40° in ethanol isn't practical for everyone, or dry ice wasn't available at time of extraction. Or maybe it's simply boring.
Anyways, saponification is basically treating fats with alkaline compound (usually NaOH) to create water soluble salts (known as "soap salts"). If you have cannibanoid acids as starting product, you would also create salts of carboxylic acids, making them water soluble as well, which is not what you want. But if material (crude oil) is decarboxylated, then treated with aqueous NaOH, everything fatty and fat-soluble should become water soluble. Whereas ∆9THC would not. You could separate with a nonpolar solvent, perhaps with something like a monoterpenoid, if a naturally-occurring solvent is of utmost importance. This is often part of the " degumming" or [decolorizing?] process in edible oil refinement.

Our best short path distillation results have been after winterization, with both the Kugelrohr and the Pharmgold Trommel molecular still test sled.

For de-coloring we use a chromatography column, with a proprietary mixture of random sized chromatography beads and rare earths, that we get from oregonmedicalgrowers.com. It comes out close to transparent, with THC typically in the high 90's.

I'll take a picture next run to demonstrate.

Do you have a working URL for them? That site doesn't work.

I offer classes teaching people to make clear raw with a short path distillation setup and heidolph brand rotary evaporator.. If interested please PM ME>

Sent you a friend request. Love to talk some more about coming down from WA to take a course.

Specifically what is wrong and why is it wrong.

Also this next link was recently dropped by the man who spent a lot of time designing a custom vigreaux spd head & had his work supposedly stolen and then modified to avoid patent infringement (subsequently making the head way less effective overall) and resold by Open Source Steel "the dum dum twins" as he refers to them in the videos lol

I found this one very informative for a beginner looking to get setup, we are considering buying an entire setup from jbv /Summit Tech, any one have any input / advice? good idea/ bad?

God that OSS video makes me laugh/cry every time I see it. So much wrong and terrible information in it.

He has a few good points. He also comes off like a half retarded asshole so again stay away from Summit at all cost. Like 50% of the stuff in his video is false or inaccurate.

Agreed.

Lol at people trying to be "the one who taught us how to do it".
The number of undergrad students laughing their asses off at us right now...

I'm interested in this de-coloring tek, what's the solvent? anything used to push it through the column besides gravity?

I'm trying to find a some definitive answers about the molecular distillation process and it's ability to remove pesticides. I see that Pope advertises insecticide removal. I sent an inquiry to the company a minute ago and hopefully will hear back.

I am wondering if anybody here can answer if substances like Eagle 20 and other fungicides are able to be isolated and left behind. From my understanding the boiling point is much higher then the cannabinoids and should be able to be separated by the process.

As long as there is a reasonable separation of boiling points (>40°C) there shouldn't be any problem removing it through distillation. Keep in mind that the compound you are trying to separate should remain stable at such high temperatures and that's not always the case. I would have to look into it more before a definitive answer but I believe eagle-20 might break down under that temp. If it doesn't then its ok to distill.

What do you know about sulphur during distillations?

 

[Daub Marley]

What do you know about sulphur during distillations?

I have no real experience with it, but I could give you educated guess as to what is going on.
Sulfur is like oxygen in that it likes to bond with other molecules around it. Once bonded it becomes a new and different molecule. So what I'm saying is that it bonds with cannabinoids and whatever else might be in there.

 

[shortwave360]

Okay... I have found this list of temps for the common cannabinoids. I also learned that eagle 20 (myclobutanil) has a boiling point of 390.8 *C

info: http://sitem.herts.ac.uk/aeru/ppdb/en/Reports/478.htm

I'm going to assume for now that molecular distillation will be able to separate the toxic compounds unless someone can correct me and site the info.

Δ-9-tetrahydrocannabinol (THC)
Boiling point:157*C

cannabidiol (CBD)
Boiling point: 160-180*C

Cannabinol (CBN)
Boiling point: 185*C

cannabichromene (CBC)
Boiling point: 220*C

Δ-8-tetrahydrocannabinol (Δ-8-THC)
Boiling point: 175-178*C

Myclobutanil BP is 202-208 C, and Eagle 20 is a mixture of myclobutanil and napthalene

Am I reading the information incorrectly from the site I posted? From my understanding of the info presented is how I came to that conclusion.

Thank you for the clarification btw!

Here is the source I was quoting:

I've had some REALLY gnarly sulphur smells going on during distillation before, multiple times. (I don't source the shit, I'm just a hired employee). EVERY time this has happened I've gotten really low potency oil, aside from the test results and the smells during distillation it was a normal process. The resulting oil was nice looking (although cloudy, not dewaxed). Test results on these runs range from like 18 percent thc to the 50's. The worst smelling runs were the lowest potency.

Big question for me is, What is the other 80 percent on my lowest test result? I cannot tell a difference having smoked it even. I'll post the actual results if anyone cares but seeing as sulphur is commonly used I think it is an important topic of discussion.

It's hard to say why the potency would be so much lower in those runs. If the sulfur does bond to a cannabinoid then it would become an entirely different molecule. THC with sulfur wouldn't be THC anymore so the tests wouldn't pick it up. I'm not saying this is what's going on I'm just giving a possible scenario.
