Pure ZHO extraction solvent

True, I meant the ~100F to read "about 100F", so as to point out it is in the ballpark with Pentane at 36.1C/97F.

Dimethyl ether, is based on the ethane molecule split in half with and oxygen molecule, leaving one methyl leg on either side and is also relatively non toxic.

It should be easier to purge than butane, but is more water soluble.

It's not, though. DME (Dimethyl Ether) is what is in the can of MZ12X.
And has a boiling point of -11F

DEE (Diethyl Ether) is not whats in the can and has a BP of 94F

Dimethyl Ether, not Diethyl Ether.

Diethyl Ether's on the DEA watch list...

thx sky, kcar and GW for all the detective work :)

my further thoughts/questions...
I just cleaned the pool for a spring cleanup here in Phoenix
and had time to ponder...

if, then, your didn't have to purge...
I guess you wouldn't really have an 'absolute' extraction
because of the water content...
but
the upside as far as medicine, would be that you get to keep more canabinoids and turpenes???

Do I have this right?

Per the definition of an "Absolute", you need to start with an non polar extraction and redissolve it in a polar solvent to drop out the plant fats and waxes by lowering the temperature.

The process does lose monoterpenes, so if you could skip it, you could retain more of them.

I haven't done a dimethyl ether extraction, but noting its low dielectric constant, it probably does extract some plant waxes as well. No feel for how many, if the extraction is done frozen. Perhaps one of the forum chemists can pipe in?

I don't mean to be a proponent nor opponent..
but a simple question:

If, as you say, it is 'relatively' non-toxic, being 1 benefit over butane..
then
my question would be 2 fold:
1. Is it necessary then to purge it at all?
and
2. If not, then could you hold ON to those turpenes captured by NOT having to (heat) purge?

thx ahead 4 thoughts on this.

Yes, you still have to purge. The puddle surface needs to be liquid for the molecules to readily escape.

Thanks K-Car for being first to spot the disparity! Good job!

Just checked for dimethyl ether on the DEA watch list, and that appears to be true.

I'll check Monday with American Scientific for a reagent grade sample to experiment with.

I will also contact ZHO for samples and look for a new lab.

The dipole moment for DME is higher than chloroform and lower than DCM; definitely polar when compared to butane. The dielectric constant of diethyl ether increases substantially with decreasing temperature, maybe dimethyl ether is the same - I can't find any low-temperature value. A pulling comparison with butane of %yield and %THC would be in order if it wasn't flammable - since it is, there isn't much cause to substitute.

Your question has been anticipated and answered, lol,

"PUREZHO 5 days ago

MZ12X pulls a lot and if you don't pay attention it might pull too much."

That's from Ron at purezho in the comments section of this MZ12X Organic Degreaser YouTube video,

http://youtu.be/Yfrl_noIprA


There are several pages at this site touting it's superior dissolving power...

http://www.tarimsalkimya.com.tr/dimethyl_ether/eng/cozuculuk.php

"The Solvency Parameter is a calculated value that depends on the heat of vaporization, vaporatization factor, temperature and molecular volume. In comparison to HC-based propellants, DIMETHYL ETHER (DME)’s solvency power is remarkably higher."

China is the largest supplier DME worldwide at this time, if PureZho's Korean DME isn't good enough or cheap enough...

ok.. well anyways.. I had a friend who used some of the mz12x .. and if u try to make it the same way u make bho. u will end up with a shitier product.. hes found that.. 1 . it stips a lot more undesirables.. so u need to use 3 dishes.. and do a single spray.. and pay attention to color change.

he decided to try methylene chloride reagent grade to see if just doing a quick wash.. will be any better then this BS there trying to pull..

personally I think this stuff is equivalent to a quick rinse iso.. and if ur not paying attention.. u don't get that nice golden stuff u get that dark CRAP..

so ill be sticking with my butane.. for now..

Reagent grade Methylene Chloride, is still Methylene Chloride, which is a poor choice for health reasons.

Especially since it sounds like it isn't Methylene Chloride, but Dimethyl Ether anyway.

I would not trust a company, whose limited webpage, calls HaloAlkane HaloAlklane.

Maybe run a spell check.

Methlylene chloride, as most chlorides are cancerous. Had Kik-it extractor in 1970's, and it was nasty. Everyone said nasty chemical taste.

Was using to apply to some bud, to improve, not straight oil.

Stopped using it after 2 runs.

Just at Capital Butane site. They are moving to bigger facility, and releasing new product next week. It was 95% n-Butane, and claimed no mystery oil, for current product.

I just did our first run with the MZ product and couldn't be happier with the results. It makes a beautiful product that honestly taste better than any other oil I have tried.

On the other hand if it turns out to be poisonous snake oil, the rapscallions can find out how well their MX12X Organic Degreaser works to remove a tarring and feathering... ;-)

Capital Butane is welcome to send me a can or two of the new lot for residual testing, Ken knows me and has my address and contact info....

Had already suggested that to Ken.

I am an idiot, but trying to figure this stuff out.

Isn't percentage of n-Butane, iso-Butane and Propane a factor in quality? Would it be more of an issue in recycler, as opposed to blasting?

butanemsds.com says most residue from mirror test is waxes, used to lubricate lighters. If so, are they harmful?

Do not mean to question, but I over evaluate everything.

Thanks!!!

Propane does a good job extracting, but is harder to recover because of its low boiling point. The good news is that it is easy to purge without losing monoterpenes.

I've heard that theory, but that isn't the case as far as I can tell. The analysis that I got sending in mystery oil, showed it to be a random mix of about what you would expect to see as residuals at the low PPM and PPB range.
