Experience with Dexso and Dimethylether?

AceHaze · Aug 24, 2016

Hi, guys

I'm looking for some reviews about the Dimethylether extraction method. It sounds very promising but I don't know if it's better/safer than bho.

I'm want to make my own extracts but I don't want to spent too much money on equipment. Goal is to get a clean product in the end.

Do I have to use a vacuum pump after the extraction with Dimethylether to get a safe extract or does it evaporate on its own after some time on the heater?

Peace
Ace

Dexso extracts quite well but brings out more green than butane so i find useful to do more smaller blast tubes than a big one to reduce contact time of solvent. It evaporates quick in an open boiler just like butane or even faster. The company selling it says its free from mistery oil but a test would be nice.
I find dexso able to bring out certain flavours more than bho..i think for the difference in polarity.
Personally i doubt you will be able to remove all the solvent molecules without some expensive equipment but if you follow some rules you can get really tasty and clean extracts..

Miracle Dabs proves you can get nice extracts with basic home equipment..this is a pic from his work..

There are at least three threads on DME, search for the original product name MZ12X.

I'm extremely glad to hear it can be used in a CLS!

As I just posted up, a gaseous state chromatography test of the gas doesn't reveal the mystery oil, you'd need direct inject liquid chromatography for that...

From their Certificate of Analysis:

"Method
The gas of the sample was sprayed in a Headspace Vial, which was immediately closed after complete evaporation of the liquid gas. A portion of the sample was afterwards analysed by GC-MS and GC-FID." That statement is quite a twister, but to make any sense it seems to be saying they let a sample of liquid DME boil off, and then analyzed what was left (this is how GW did the original canned butane analysis,) but their results indicate there was no non-volatile residue... maybe, but I have strong doubts.............

Send me a couple of cans, and I'll test it for non-volatile residue (mystery oil,) and post up the results. Better yet, test it yourself... follow the above link to my test procedure.

Thank you for your input, guys!
An independent test would be really cool...

Here's the residue test I did on the MZ12X dimethyl ether,

https://www.icmag.com/ic/showpost.php?p=6248773&postcount=18

Only 0.006g of non-volatile residue (mystery oil) from a 500ml can is pretty damn clean... compare to the butane I've tested in my Signature link below.

Sang Kim who brought out MZ12X can be found here,

Btw, I don't know if we here brought this about (G.O. Joe!!!) but the DME entry at Wikipedia now states,

"Unlike other alkyl ethers, dimethyl ether resists autoxidation. Dimethyl ether is also relatively non-toxic, although it is highly flammable."

https://en.wikipedia.org/wiki/Dimethyl_ether#Safety

It doesn't form dangerous peroxides!!!!!!!!!

So, just watch your seal materials, and run it cold/fast.

AceHaze · Aug 25, 2016

Thank you for the links. I think, I will give it a try...

SkyHighLer · Aug 25, 2016

Due to the low boiling point of DME, beware of creating quick temp shifts in any glassware, pre freeze your tube with the material packed and sealed in it, don't shoot to a warm Pyrex dish (raise the temp slowly after extracting.) You'll probably wish you had insulating gloves, Polar Penguins $10,
http://www.ebay.com/itm/Size-Medium...492186?hash=item43d56ce45a:g:g~sAAOSw6aVUprpC

If you're going to open extract, a metal tube with feet is the way to go with this stuff, like they have at the Dexso site,

"The magnetic tripod is convenient, easy to use, and makes the extractor easy to transport. It offers you protection against frostbite and protects the installation against static electricity."
http://www.dexso.com/index.php/en/products/extractors

Personally, I expect a CLS run cold as hell with DME to produce wicked product.

Im currently trying to track some of this stuff down in so cal.....hopefully i can come up on some soon otherwise the $100/L chem supply stuff might be in order.

SkyHighLer · Aug 26, 2016

^ I contacted Dr Z/Sang Kim for current California MZ12X distribution info. If you're interested, I've got a couple of cans - Inland Empire... I'll even lay a few cases of butane on you, free, surplus from my testing. I left contact info via a Visitor Message at your ICMAG Forums Profile as I see you don't have enough posts to pm me.

what a gentleman.

IE eh? I grew up in berdookie. Did a couple bids in the marines and then moved back to delrosa/lynwood hood for a few months before running back to sandyeggo. I'll forever miss easy access to bakers and rosa marias/cucas but i visit often.

thanks skyhighler ill be in contact!

SkyHighLer · Aug 26, 2016

He's on his way up, so smooth in Cali......

is where MZ12X distributor list is....if incline email me lghllc@gmail.com and I will help you out.

SkyHighLer · Aug 27, 2016

The California phone number didn't work for me...

Sorry mobin, the separatoy funnel was right there in the box behind the Buchner... I must have had a subconscious desire to hang onto it! :biggrin:

THC-A was flash vaporized at precisely 666F (352.222...C)

and did I ever ramble on.........................

mobin · Aug 27, 2016

Skyhighler was a hell of a gentleman! Couldn't believe the hospitality. He gave me more goodies than i deserved. Ill report back with greater detail later. Looks like ive got some dme to extract with....time to see its worth is for our purposes first hand...thanks again sky...ill report when the thca wears off.... :woohoo:

sadpanda · Aug 27, 2016

SkyHighLer firstly thankyou for sharing all your butane tests, really awesome!

but im wondering what constitutes are in the residue???

SkyHighLer · Aug 27, 2016

I have a suspicion the few brands with very near clear transparency, and no offensive odor may have a simpler composition, but the stuff Gray Wolf collected, and had a third party GC-MS performed upon was downright nasty, zillion long named chemicals, most of which you should never ingest beyond infinitesimal amounts, and that's what it turned out to be, when you calculate the most amount of solvent that might be used (low grade trim run, etc.) versus the amount of product, there isn't going to be enough poison present to be of concern when dabbed.

I'm still dabbing BHO I made three years ago with the original Vector, check the list, it's obviously not the brand I'd choose again... but I don't knock my oil to myself, my lungs have only gotten better over the last three years, and as I've stated before, I can't find the MO notes in my oil, and that's in direct comparison with the best commercial product made with distilled butane/propane.

Thanks for taking the time to dig for the understanding, this one is simple, but so buried...

If I may call a spade a spade, Specialty Analytical screwed up the quantitative testing, badly, how I got involved so deeply. My thanks to the Great Spirit for providing such 'game.'

So me and a partner came up with a 1/4 of "red seal" brand extracts and a few grams of co2 oil that i think we'll clean up with the dme. Ill try and take pictures of my process and record data like one should. Im thinking freeze everything up with some dry ice, dissolve in dme, winterize in 99% iso, pour into pyrex nice n thin, hood pull the solvents off at 95* or so and see what we end up with. Any request or recommendation is welcomed and ill post up tomorrow when we start doin work!

those test results are quite an eyeopener, was not expecting such a large list like that! think i'll stick with ethanol lol

I know there are some lovers of ISO extracts here, and I don't think slightly under purged ISO extract is absolute poison, but really, ISO as the final solvent... why? One of the selling points of DME is it's extremely low Bp, down there with pure propane... it practically purges itself at room temp. I'd rather have what's left over from a raw, unpurged DME extraction then even the best ISO extraction, even if you've gone so far as to decarb the ISO product at 250F until the bubbles stop, ISO hangs, and that awesome buddy of yours you brought with you shouldn't be consuming ISO period. Unbelievable cancer survivor... finally found Gerson and cannabis after years of cutting and poison, got his life back, dude looks good enough to walk into any bar and pick up on any chick even without telling his story, though the long surgery scar from the brain tumor does provide lead in..... thanks for sharing your story dude, makes me think of getting my Champion juicer out, inspiring!!! So, save the DME for a single solvent dry ice soak of some nice trim or nuggs, and decarb that shit I hope was donated to you, eat it, don't even mess around with putting it in a vape pen or something, yuck dude, tell them how I spoiled your elfin bearded, wickedly tattooed ass by putting it to a waterless dab off an old school soldering iron tip.
