Pure ZHO extraction solvent

The testing on R-134a must be done, even if only to set standards to make sure no one's using it. Do you really know where your buddy's oil came from?

I agree that it should be tested to see if the final extract can be 100% free of all contaminates left behind. If so, R134a could be a very practical solvent to a closed loop system. I really hope that nobody is blasting R134a into a Pyrex dish without knowing what they're really getting into. Let alone the fact it's illegal to be venting it into the atmosphere.

These guys included R-134a on their short list,

"We conduct plant extractions using a variety of solvents including butane, hexane, hexene, ethanol, carbon dioxide, and r134a refrigerant."



"Israeli Legal Cannabis Pharma Operation

Jay W.
Attorney
I have a fully permitted medical cannabis operation in Israel, and we require funding. The current cannabis seed market involves strains that are unstable and typically fail for the required international germination rate. Our company will produce custom strains for companies to be released when US legalization occurs. We will also be selling cannabis extract legally for use in pharma and vapor cigarettes.

Our genetic library consists of over 250 strains, which can be crossed and stabilized to create strains with customized characteristics (i.e. flavor, aroma, experience, ease of growth, yield and the like). We conduct plant extractions using a variety of solvents including butane, hexane, hexene, ethanol, carbon dioxide, and r134a refrigerant.

Additionally, we will be able to conduct research for other companies who do not have access to legal cannabis facilities. As long as it does not involve human or animal trials, we have government permission to research.

The business will be conducted internationally. Additionally, we have a proprietary delivery method that could satisfy the DEA's desire for control and preventing abuse. We are looking for both funding and customers. Our operations have already commenced with funding from the current Israeli CEO. For more details, please contact me."

Hmm... I'm not sure where you get that impression. The only part of this that is correct is the fact that you don't need a Section 608 EPA certification to purchase "substitute refrigerants" such as R134a. This is from the EPA's FAQ:


Although the replacement refrigerants, such as R134a, don't contain (or have very little) ozone-depleting substances, we in the HVAC/R are to treat them as so, and any venting is a big no-no. Now there is "green talk" about the "global warming factor" of HFC's and the various substitute refrigerants. And some talk of alternatives for the alternatives...

So if this company is referring to R134a, the only way this would be legal, under federal law, is in a closed loop system.

Personally, being as how I have much experience handling refrigerants, I have always pondered common refrigerants replacing butane (although butane is of course, a refrigerant, as R600 is N-butane AKA "normal butane" and it's cousin, R600a isobutane) in this sense. <snip>

Thing is, it doesn't have to be a "refrigerant" at all...how about we call Pure ZHO the equivalent of a canned gas duster filled with 1,1,1,2-tetrafluoroethane (R-134a?)

"The Society of Automotive Engineers (SAE) has proposed 1,1,1,2-tetrafluoroethane (HFC-134a) to be best replaced by a new fluorochemical refrigerant HFO-1234yf (CF3CF=CH2) in automobile air-conditioning systems.[12] California may also prohibit the sale of canned 1,1,1,2-tetrafluoroethane to individuals to avoid non-professional recharge of air conditioners.[13] A ban has been in place in Wisconsin since October 1994 under ATCP 136 prohibiting sales of container sizes holding less than 15 lbs of 1,1,1,2-tetrafluoroethane, but this restriction applies only when the chemical is intended to be a refrigerant. The ban has been lifted in Wisconsin in 2012.[14] It appears, for example, that it is legal for a person to purchase gas duster containers with any amount of the chemical because in that instance the chemical is neither intended to be a refrigerant [14] nor is HFC-134a included in the § 7671a listing of class I and class II substances.[15]"

"Tetrafluoroethane, when compressed as inside gas duster cans, is a clear liquid which boils when exposed to atmospheric pressure at room temperature (as seen here) and can be extracted from common "canned air" canisters by simply inverting them during use."

Hmm... I'm not sure where you get that impression. The only part of this that is correct is the fact that you don't need a Section 608 EPA certification to purchase "substitute refrigerants" such as R134a.

Clean Air Act Title VI. And "I'm not sure where you get that impression [that] The only part of this that is correct", this site not being hvacmag. Office Depot sells tons of 100% (alternate suspect) R152a for the express purpose of venting the can's contents, so wouldn't they be in jail? R12 is a controlled substance:

42 USC § 7671c: Phase-out of production and consumption of class I substances (a) Production phase-out Effective on January 1 of each year specified in Table 2, it shall be unlawful for any person to produce any class I substance in an annual quantity greater than the relevant percentage specified in Table 2. The percentages in Table 2 refer to a maximum allowable production as a percentage of the quantity of the substance produced by the person concerned in the baseline year.

(b) Termination of production of class I substances Effective January 1, 2000 (January 1, 2002 in the case of methyl chloroform), it shall be unlawful for any person to produce any amount of a class I substance.

(c) Regulations regarding production and consumption of class I substances The Administrator shall promulgate regulations within 10 months after November 15, 1990, phasing out the production of class I substances in accordance with this section and other applicable provisions of this subchapter. The Administrator shall also promulgate regulations to insure that the consumption of class I substances in the United States is phased out and terminated in accordance with the same schedule (subject to the same exceptions and other provisions) as is applicable to the phase-out and termination of production of class I substances under this subchapter.

42 USC § 7671g - National recycling and emission reduction program (a) In general (1) The Administrator shall, by not later than January 1, 1992, promulgate regulations establishing standards and requirements regarding the use and disposal of class I substances during the service, repair, or disposal of appliances and industrial process refrigeration. Such standards and requirements shall become effective not later than July 1, 1992.

(2) The Administrator shall, within 4 years after November 15, 1990, promulgate regulations establishing standards and requirements regarding use and disposal of class I and II substances not covered by paragraph (1)

So, 17-52-99 knows R12. I have failed to find similar language regarding the replacements. 42 USC § 7671g again:

(c) Prohibitions (1) Effective July 1, 1992, it shall be unlawful for any person, in the course of maintaining, servicing, repairing, or disposing of an appliance or industrial process refrigeration, to knowingly vent or otherwise knowingly release or dispose of any class I or class II substance used as a refrigerant in such appliance (or industrial process refrigeration) in a manner which permits such substance to enter the environment. De minimis releases associated with good faith attempts to recapture and recycle or safely dispose of any such substance shall not be subject to the prohibition set forth in the preceding sentence.

(2) Effective 5 years after November 15, 1990, paragraph (1) shall also apply to the venting, release, or disposal of any substitute substance for a class I or class II substance by any person maintaining, servicing, repairing, or disposing of an appliance or industrial process refrigeration which contains and uses as a refrigerant any such substance, unless the Administrator determines that venting, releasing, or disposing of such substance does not pose a threat to the environment. For purposes of this paragraph, the term “appliance” includes any device which contains and uses as a refrigerant a substitute substance and which is used for household or commercial purposes, including any air conditioner, refrigerator, chiller, or freezer.

What product are you referring to?

"Can I smell Suva® or ISCEON® Refrigerants?
Most refrigerants have such a faint odor that they can be difficult to detect even at dangerous levels. Do not use smell as a test for safe levels of refrigerants in a work area. Frequent leak checks and air monitoring are the only adequate ways to determine that areas are safe for entry and work."

http://www2.dupont.com/Refrigerants/en_US/assets/downloads/k10925_safety_of_DuPont_refrigerants.pdf

I have six cans of DuPont Suva 134a on it's way to me, I'll let you know in a few days if I think it has an odorant.

 

[Kcar]

No, in the 'canned air' dusters. Not in the refrigerants...

 

[passby]

All these talk about 134A but does anyone ever tried? 134A does not work for your info. Wax is too oily for 134A to pull anything out on open air extraction. It requires heat to work when you are extracting essential oil out of any plant matter.

 

[SkyHighLer]

I have six, 12 ounce cans of R-134a coming tomorrow. I'll squirt a can into a Mason jar to check for residuals, and if the 'smutz' at the bottom of the jar looks similar to what I see from a similar amount of canned butane, I'll run an ounce of herb (open air, in a Mason jar.) I'll probably do a standard vacuum purge, about an hour at 115F down to -29.5" Hg. And if I get that far I should send it out for testing... ;-)

Fedex needs an extra day, should be here 10/25/'13

I think Greenjunky1 may be passby.

 

[purple_man]

lolz sounds like a bunch of marketing and 0 scientifical proofs... "msds will be disclosed later..." come on, those guys are for real??? talking/marketing folks into using their "system" and their "special" solvents, without disclosing critical data???

remember gang, when something sounds to good to be true, most of the times it is...

blessss

I think Greenjunky1 may be passby.

"greenjunky1 13 hours ago
R134a is hydro base where wax is not. You cannot do cold extraction with 134a FYI."

Guys I saw this at the Denver , it's not even on the market until Dec. everything will be released then is what they r saying . It's very cool to see in person I can tell u that . Carbon levels came back at 50 ppm on the sample.

If it's not R-134a, something new and better, why bother with a small scale marketing scheme, directed at cannabis oil extractors? Just call it a safe and sane solvent with culinary uses that can be sold anywhere and everywhere.

I'm still going to test the canned R-134a refrigerant, Fedex now says tomorrow...

10/25/'13 and it's here, results asap, sweeter smelling than canned butane, no tire odor. The 'smutz' residue at the bottom of the Mason jar seems to be an amount similar to the tests I've done with canned butane. Interesting, the residue froze during the final boil off and turned into a fluffy powder, it returned to it's oily state as the jar warmed. Waxy paraffins? I hope to try a cannabis extraction with it this afternoon.

10/25/'13 evening, a five minute quick soak in R-134a yields nothing!!! Stuff has zero cutting power.

Picture shows the Mason jar, filter paper, and ground nuggs, next to the evaporating dish. That little piece of paper towel contains what I wiped out of the evaporating dish after boil off, it seems to be residue from the R-134a, there is no scent of cannabis.

Now, wtf is Pure Zho?

They need to have tested,

The percentage of the main gas(es) in the can

The percentage/ppm of impurities in the gas

The percentage/ppm of gas(es) in a samples of cannabis oil (with varying degrees of purge.)

The percentage/ppm of gas impurities in samples of cannabis oil

The percentage/ppm of gas(es) in vaporized samples of cannabis oil (with varying degrees of purge.)

The percentage/ppm of impurities in vaporized samples of cannabis oil

They sound like foreigners trying to get rich quick to me. I've contacted them, and am awaiting a response. I asked for content disclosure and msds. If they're using citric acid, it's very bad for you and should not be smoked or consumed.

Hmmm... Got my interest.
