Vacuum distilling butane

[Gray Wolf]

Wow gray wolf. You understand how to scfe and you encourage butane as a solvent of choice isn't kosher. I recently beat manufacturing charges on my own knowledge of the law and a statement proving legitimacy and ultimately DA Rejected case. I have no bar membership yet represented myself like a big boy not only by copping it was mine, but what its legitamate use is in an andustry where I am trying to help correct is the bho being to tempermental, fast spreading, unnecessary methods that cost people their lives.BHO is gave hash oil a rael bad name

Sorry that you don't consider the way I conduct myself kosher bro but let me congratulate you on the way you handled yourself like a big boy with the DA.

Allow me to disagree with you on the point that BHO "is gave" hash oil a "rael" bad name.

I have come to the conclusion that it is the bone headed idiots, that believe they have all the answers, and don't accept input or pay attention, who are responsible for any bad reputation that BHO has gotten.

May I observe that you are also in the CO2 extraction business, and note how many forums you have been ejected from for spamming, and for blasting the pages with hearsay anecdotal statements that fall apart on close scrutiny.

I did you a favor by deleting your last post on Skunk Pharm Research, because frankly it made you sound like someone who needed a keeper, and I thought you might want to keep that part a secret, in case folks with a syringe and white jacket are already circling and eyeing you strangely.

Cannabis oil can be fractionally distilled, but it is above my pay grade.

Old used kugelrohrs are very simple to operate, but also rare and probably not on sale. But a connected operator out west should have no problem profiting from a brand new unit in time.

 

[trichrider]

how long is the waiting list now?

been a year since putting my name on it without response.

got papered, saved my monies, waited patiently...what else must one do?(won't go down...).
i used to be excited about this, but lately just resigned to the fact that iso will have to suffice.

Cannabis oil can be fractionally distilled, but it is above my pay grade. Joe, our biochemistry brain trust, is working on that issue, but alas is over the hill and far away, getting heart surgery for his last man child.

I will pick his keen alleged mind upon his return and get an update on his progress.

He has an open experiment using Chromatography to separate the components and light refraction to redirect the streams to different containers.

He picked up the used fractionator off e-bay, and you can see it in the background, behind the vacuum distillation experiment.

Dear Gray Wolf

As always your answers are the best..
Look forward to hearing more!!

All the best

Grey Wolf, I received my terpp from terpp extractors, set my terpp all up and did a distillation run on some butane. I added 5.5 pounds to my 6x12 collection pot, setup my recovery tank in dry ice and started to transfer then I got distracted for about ten minutes towards the end of the recovery and realized i went into a vacuum around -10hg.

I see a good amount of mystery oil in the pot, cleaned it out real good, but im wondering if i might have boiled off any pentane that might have been in my N Tane.

I was never over 85* on the collection pot water bath.

My butane came from Jay Coltrane. (thanks Jay!!!!) 99.5% pure.

Do you think i should distill it again and keep a better eye on my guage or do you think im ok?

Thanks man!!!

 

[Rickys bong]

OregonKushFarm was your system fully cleaned before the first run?

The first thing to do with a new system is to run a small quantity of butane through it to clean out any oil from manufacturing.
It should have been clean when you got it, but....

There should be zero mystery oil from 99.5% N-butane stock.

Try it again, I'd guess you don't find any oil left behind on the second run...

GO joe reppin Kugelrohrs way before they were cool! LOL why did we need 2 60 page threads about the clear when OG joe had already told us

There's all sorts of tricks in ICmag threads ... that's why when folks as questions, I say look it up on ICmag

Petane boils around 56C at 760,000 microns, I roughly estimate around 35C/95F at 254010 microns, based on the following program:

You are close enough to the boiling point that you will be carrying over some Pentane from sublimation. I would personally run it again, because it is lots easier to remove from the butane, than the concentrate.

That brings us to perspective. We distilled 48# of JColtrane/Praxair 99.5% Instrument grade and got mystery oil, but as RB suggests, not a huge amount.

I am dropping a tank off at a third party lab today, and we will get some empirical numbers, but the butane and propane we've distilled thus far, was not heavily burdened with MO.

If you have already distilled it once, it is ostensibly cleaner than the lighter butane mix's currently used for open blasting, where all of the MO is left in the concentrate.

 

[JColtrane]

Here is what the MSDS says a/b the gas I supply:

2.5 Instrument grade - 99.5 wt% (liquid phase), H2O < 5ppm/w, Propane < 500ppm/w, Isobutane < 2500ppm/w, C5 < 1000ppm/w, Sulfur < 1ppm/w

I'll work on getting a link to a copy today, and post it here

There was a little MO in the mix, not as much as ive seen with can tapping. I will run it again for sure. Much easier to get pentane out of butane tan the oil for sure.

Thanks Grey Wolf.

Grey Wolf, Do you think our solvents become oversaturated in very light terpenes when using the same solvent over and over? Maybe this is why some peoples' solvent tanks "corrode." Just curious. Been running Carbon and 3a/4a mix during distillation to avoid this and moisture.

No question that the butane picks up the monoterpenes and turns into a "gin", but haven't observed anything leading me to believe it is over saturated, and as we are recovering it as a vapor, I wouldn't expect to see more than a "gin".

The corrosion in the carbon steel tanks is most likely caused from water accumulating and sitting in the bottom of the tank.

Always a good idea to regularly vent any accumulated water.

 

[MrSpectre]

Thanks! Good to know. I blast using my vapor outlets on my tanks so I can get every drop of tane out. I then take them outside turn them upside down and release both valves and then pull a vac to avoid water and be ready for my next run. Have some 3a/4a on the way so some experimenting will be necessary
