Also note that on the picture of the can your provided it says propane on it

I believe that's an unbreakable world record - I have actually missed it!  :o

CH2 FCF3 CH3

For sure that's not a formula of existing compound. Hard to say anything else. Can you post these printouts? Or give a link to them?

I also agree with you i have been in chemical engineering for years and looking at the way this so called green gas is presented seems to be nonexistent. CH2FCF3CH3?????i scanned by books in organic chemistry niether solomons and mcmurry didnt mention about this compuond plus i try to devise on how to synthezise the said compund but the patheways are very not very but extremely difficult!
so i guess its a non-existent compound CH2CH3 maybe but CH2 FCF3 CH3 its hard...

Definetly looks like a misprint or a typographical error to me. And the product may be CFC free making it "green" but it is not HCF free, which is still bad for the environment. I agree with enahs that it is a bottle of propane with some sort of additive to protect seals or reamove moisture etc.

The commodity bit says propane and thats what they're declaring it to Customs as and paying duty on.

Its would appear to be:
96% propane
0.5% ethane
3% butane
0.3% silicone oil
0.2% ???

as far as i can see it is CFC and HFC free.

The CH2 FCF3 CH3 part of the name is completely made up bollocks.

Does the MSDS you have give either
CAS No. in section 2
or
UN No. proper shipping name and PG in section 14?

these are from a MSDS on one of the Green Gases:
UN No. 1950
proper shipping name AEROSOLS, flammable
CAS 74-98-6 (propane)
CAS 106-97-8 (butane)

I will find the download links for the MSDS sheets -- I have several of them somewhere.

As DrCMS pointed out, it's a can of propane.  Legally, the phony and incorrect chemical structure in front of "green gas" is likely part of the tradename (similar to Nylon or Teflon).

Where did you obtain the MSDS for this product? No retailer I know of can provide one.

If you can't find a commercial supplier from the link below, it may not be readily available.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Mitch before you post a generic answer to finding an MSDS try checking that you can find the specific chemical asked about with the link you've given, that way you wont look like a dick when people try and can't find the MSDS they asked for.

CH2 FCF3 CH3 would all be to reactive to exist for a prolong time in a cannister.
