Talk:Chlorodifluoromethane

Untitled
Does anybody know what this stuff should cost? Could be good information to add. I just paid about $240 US for 2 pounds of this stuff for my home AC unit. Seemed like a rip off. 75.75.98.217 22:43, 14 May 2007 (UTC)

It is a common practice for repair people to artificially inflate the cost of provided goods in order to cover the cost of the service call..

Cans of HFC 22 for use in air guns are NOT Chlorodifluoromethane!
Every single place I've seen selling it, the shipping weight is nowhere near what it ought to be if it were actually CClFCH, the shipping weight, that is, the product and the can its sealed in combined, is always between 1/3 and 2/3rds of what the weight of the CClF2H alone ought to weigh! Chances are whatever is in those cans is actually propane.

I am deeply disappointed to make this disclosure. I was really hoping that, perhaps, the 2nd amendment had provided some sort of loophole to bypass the draconian restrictions put in place by the EPA as a result of the Ozone Hoax. Not so. Instead, what we have here is a company called "Ho Feng Corp" portraying their product in an extremely dishonest manner in order to confuse those who might use canisters of propane that cost over ten times less than their branded "HFC 22"...

 * And here I was thinking airguns used canisters of compressed CO2, nitrogen or just plain, well... air. But conspiracy wonks gonna wonk, I guess. 146.199.0.169 (talk) 20:57, 17 June 2019 (UTC)

R-502/R-409A?
According to List of refrigerants, R-502 and R-409A are mixtures which both contain Chlorodifluoromethane, one of them containing 60% of it. Wouldn't that make them also illegal under the Montreal Protocol, and therefore NOT a good substitute?? —Preceding unsigned comment added by 74.87.96.159 (talk) 03:20, 4 August 2008 (UTC)

HCFC-22 corrosion potential with aluminum
Has anybody ever heard of experimentation/testing being run regarding the corrosive properties of HCFC-22 to aluminum (primarily 6061-T6). It looks like there is some sort of reactin to "Group 2 - Alkaline Earth metals but nothing specific to aluminum (understood that aluminum is composed of many of the alkaline earth metals). It would be nice to see a report done on the subject. —Preceding unsigned comment added by Sandcreature (talk • contribs) 19:56, 17 June 2009 (UTC)

Why R 22
why we call chlorodifluromethane as R 22. Please explain —Preceding unsigned comment added by Pram3012 (talk • contribs) 09:58, 6 October 2009 (UTC)

Already have data for 2014?
In the 'Price History and Availability' section, there's data for 2014. But it's 2013 now. How do we have next year's information?152.51.56.1 (talk) 17:06, 11 July 2013 (UTC)

Why isn't this article named R-22?
The first sentence of the article states that the most common name is R-22 - which is true. Why are we using a less common name for the article title? This is a widely used refrigerant with a well known common name - the article name should probably be R-22. 72.88.81.122 (talk) 16:34, 27 May 2015 (UTC)
 * It is usual to give chemicals their IUPAC name, that is the name that chemists call them. Note for example aluminium which has confused many people. Besides, R-22 isn't all that common, and less as it is phased out, so it won't be so commonly discussed. Gah4 (talk) 02:50, 5 November 2020 (UTC)

Any reason for "MT"?
It seems a bit strange seeing the stockpile figure listed as "MT (metric tons)". There are a few things wrong with this and I hope it's just because the EPA chose to write it like that for a nonscientific US audience, rather than it being an invention of the article author.

For a start, if your units are clear and conventional, they shouldn't need subtitling - you don't see lbs or kg being subtitled (pounds) or (kilogrammes), and indeed I saw "Gg" (a rather odd, but valid SI combination, although you'd normally expect to see it written in terms of kg, maybe in standard form) either further up the article or the one I directly linked through to it from (R410a) without it needing a note of "(gigagrammes)". That it needs explaining suggests you know it's nonstandard to start with.

Secondly, the M could be easily mistaken as the "mega-" prefix, IE multiplying the given figure by 1 million; though "MT" would be a somewhat worrying "megatesla", thus a measure of a truly epic magnetic field, it could also be misread as "megatons" ... especially as that abbreviation, with various capitalisation, is routinely used for measuring the power of nuclear bomb blasts.

Thirdly, there's already a perfectly good symbol - "t", and name - "tonnes", for "metric ton". The latter term is a rather unscientific American colloquialism. At the very least you could write "metric tonnes", y'know? But all that's actually needed is replacing the MT and its subtitle with a simple lowercase t.

I'm going to change that now anyway, but I felt it bore some explanation in case someone thought it simple vandalism and blindly reverted it. We're covering a scientific subject, the units and symbols should be standard SI, which means g, kg, and t for measures of mass or weight. If you want to vary from that, go the whole hog and use pure "standard" units instead... thus, lbs, and short or long tons. If that means converting the units, it's not exactly a difficult thing to do - there's even the facility built into Windows Calculator nowadays. 146.199.0.169 (talk) 21:07, 17 June 2019 (UTC)
 * I was wondering about kt in place of Gg, but all these units are funny. If kg is the base unit, the multiple should be Mkg. Gah4 (talk) 02:53, 5 November 2020 (UTC)

propane?
The article has a whole paragraph on propane as a refrigerant. It seems that this should actually go to the propane article, maybe with a mention or see also here. Gah4 (talk) 02:54, 5 November 2020 (UTC)
