Butane Residue Test Results
- Thread starter SkyHighLer
- Start date
Let me know when you're ready and I'll get you an address and funds.
Moorpark 5X #1 had 0.006g of residue
Moorpark 5X, China, 300ml can, no date of manufacture
Moorpark 5X #2 had 0.007g of residue
Moorpark 5X, China, 300ml can, no date of manufacture
The residue had a yellow tint, and some smell.
Zippo #2 had 0.0068g of residue (six cans shot to the same test bag, this is the result divided by six)
Zippo, USA, 165g can, reads on the bottom "K1113"
The residue was clear, and had a very light pleasant smell.
The can states it's isobutane, could be... the temperature during boil off was low throughout the boil off, at the end I raised and tilted the bag to get the last tablespoonful down into a corner, and took what I believe was valid reading of 16F.
Even though Zippo didn't fare as well in the amount of residue with this latest sample, the clarity and lack of unpleasant smell to the residue still makes it a stand out product I highly recommend.
I hope to retest most the top tier brands from my Best to Worst canned butane list in the near future now that my general survey of the market is about complete.
I need a closed loop extractor in Southern California to take (for free) the left over butane from my tests, this includes the EcoGreen butane and propane tanks. I'm in the Inland Empire. Please private message me if you're interested.

Distill the butane.....period

Don't open blast.......those days are OVER. Nobody should be consuming openblasted concentrate that will clearly have Mystery oil or "residue".
Distill whatever butane you have and your good to go.

I'd rather make my own product where I know what went on during the extraction, the thing with the EcoGreen hose leaching cinched it for me. Just my opinion, carry on...

The bag is to contain the butane and residual, and it does it well. I've never had a leak, and never found even a smidgen of of residue on the outside of the bag or in the evaporating dish. That some brands of butane have non greasy, clear, and smell free residue indicates there is no interaction, and if there was, so what? Are you imagining the residue combining with something in the composition of the bag and then escaping into the atmosphere like magic?
Thanks for following the thread!
I hadn't thought about the possibility of it leaking. Nor the possibility of some mystery oil witchcraft.
Although, what I was worrying about is the worst case scenario of the butane dissolving the plastic bag and adding to/altering your residue! Therefore making the weight of residuals incorrect.
Thank YOU SkyHighLer for creating this thread. We'd be ages behind in this mystery oil game without the countless hours you have invested into this thread and all the work which encompasses it.
Cheers
You're welcome, my long lost called from Oahu today, mercy...
Finally getting some London, I guess we're at the end. ;-)

Buying proper hosing would solve that issue for you. I'm not sure I understand, are you suggesting that using canned tane is better?
I'm not sure there's much difference after distillation, but I'd much rather starting with a relatively pure product, and then putting some effort into routing it properly (ie through hoses that will not leach)
I'm definitely interested to see the results of GreyWolf's test. I'm using Power 5 at this point, so Ecogreen would be an affordable step up in quality, particularly if I gain the ability to distill and recover.
/Speaking from a point of view of someone that desires a closed loop and is trying to avoid unknown petroleum products, and has not tried any of Ecogreen's hoses.

^^^ This is what I responded to...
It's my opinion taking into consideration what I've been reading here at ICMAG, is that the closed loop systems and the techniques for using them have not been fully debugged yet.
Who did the research to ensure the various grades of hose's aren't leaching? Were the tests done under positive and negative pressure and temperatures as encountered in system? Same goes for the seals.
My quick search for a replacement for the EcoGreen charging hose that was supplied with their 'lighter refill kit' turned up several different common hoses; regular, nylon barrier, PTFE lined, and unlined convoluted stainless steel.
There's just no way to know who's using what in their CLS, or if they're even aware it might make a difference.
And then there's the pumps, I see one CLS vendor is still offering the Caresaver, which thankfully was quickly pointed out by an astute ICMAG member to not be oil free...
Oh, and the moisture, rust, and who knows what that collects in the recovery tanks...
So, yeah, my BHO made via quick soak in a Mason jar seems likely to be cleaner than that coming from some unknown CLS system, even though I'm using canned butane with a wee bit of volatile and non volatile residue.
This isn't a condemnation, just a challenge to improve.

The 'lighter refill kit' works smooth! After a flush of the system, I shot to the 500ml line on my Mason jar, about double the amount of a standard 300ml can of butane. A gummy, yellowish residue, which stank similarly to, but stronger than almost all the canned butane I've previously tested was left behind. It was still stinking after two vac purges, so I purged it again... The result was 0.076g of non volatile residue. Half that, 0.038g for comparison with a standard can of butane.
EcoGreen butane had 0.038g of residue (in an ~300ml can's worth)
EcoGreen Industries, China, 30lb n-butane tank
Going to be second from the bottom on my Best to Worst canned butane list, I suggest this not be used for open extractions.
This isn't the first distributor to be taken by surprise... my condolences.
The Yellow Jacket hose with nylon barrier worked fine, I flushed about 300ml of butane through it and the head from the EcoGreen 'lighter refill kit,' and then took a 325ml test sample.
The wee bit of residue, ~0.001g was mostly clear with a whitish tint, wasn't sticky or gummy, but is stinky, even after a couple of vacuum purges of the test bag.
I still can't imagine anyone finding the smell acceptable.
There is a massive flow of air through my extraction area, notice how nice I have the butane boiling with a little high wattage silicone heat mat fully sunk to the bottom of the dish. I have a variac coming for even better control than the wall dimmer currently employed.

Here are the Ecogreen GCMS summaries. As you can see, it has green alligators at the Parts Per Billionth levels, but nothing outside proscribed limits.
I have a call in to the lab to discuss the results and will report back after doing so.
I'll also pick up the tanks and experiment with the residuals. I'll review JC's R-290 dry powder residual sample with them and solicit their input at that time.

Big thanks to GW and EcoGreen!
Benzoic acid is by far the highest in concentration, and it's no problem, but is probably the primary source of the "dry white powder,"
"Benzoic acid /bɛnˈzoʊ.ɪk/, C7H6O2 (or C6H5COOH), is a colorless crystalline solid and a simple aromatic carboxylic acid."
http://en.wikipedia.org/wiki/Benzoic_acid
The other residuals are also so low in concentration to be of no problem, except for the smell, which is most likely the pyridine...
"It is a colorless, highly flammable, weakly alkaline, water-soluble liquid with a distinctive, unpleasant fish-like odor."
http://en.wikipedia.org/wiki/Pyridine

Nxxt 2 Zero had 0.014g of residue (two cans shot to the same bag, this is the result divided by two)
Nxxt 2 Zero, England, 300ml can, reads on the bottom "DOM 18.01.14 11:45"
Residue in the bag had a very, very slight yellow tint with little odor.
I'll add the results to the list at the head post, and to the Best to Worst canned butane list linked to in my ICMAG Signature.

I was told by a representative of Five Zero Trees in Portland that EcoGreens NButane was "refrigerant grade" and not as good as say Lucienne from a can. Our #30 of R600 was not cheap, but I will happily and safely dispose of it if it is not safe to make medicine with.
If however, GW and SKL's respective test hold true and there is no inherent inferiority to R600 refrigerant versus canned lighted refill butane, I think it should be important for patients ts growers and the like to be aware of the bias and falsity held by at least some of the staff at this club which could lead to substandard care and products for patients.a

My testing showed both butane and propane from EcoGreen to be comparable to the best of the canned butanes residual wise, but I found an out of the ordinary, foul smell from the residual. Wasn't added odorant/mercaptan, something else. It's not horribly bad or overpowering, I doubt anyone could discern it in their oil, but still, only a couple of brands of canned butane had such an unpleasant residue smell, and I noted so in my result lists, and suggested those be avoided.
Here's what I suggest, since you already have it on hand, squirt about 200-500ml into something and let it boil off, take a whiff. Your call.
There is absolutely no reason to avoid using EcoGreen's gases in closed loop systems, as long as you distill them first.
We distilled the whole of it through the terpenator. The MO was really foul. The oil we have made thereafter has been great.
I guess the questions I have now are: what "grade" is Eco Green's NButane? After distillation would it matter the grade for any reason other than bragging?
Has any one checked for MO after distilling their butane?
We are local to skunk Pharm and are very curious to see lab tests from NButane after it has already been distilled and would be more than happy to donate toward a lab test.
