From the section "Uses":

"CFC-113 has a unique property that makes it perfect for cooling systems. When it is in a gas form and compressed, it heats up, when it is expanded, it cools."

The way this is written, it seems to say that the property of "heating up" when compressed and cooling when expanded is unique to this chemical. This is *not* unique. These temperature and pressure relations are common to all gasses (see Gas Laws). MicahFerrell (talk) 21:59, 29 May 2008 (UTC)Micah Ferrell[reply]

Not all gases at all temperatures, but yes it is usual. Gah4 (talk) 00:31, 23 August 2019 (UTC)[reply]

Freon TF

Wasn't this stuff also known as "Freon TF"? That's what I remember on the labels of the 5-gallon cans of the stuff (made by DuPont) that we used to clean tape heads at a TV broadcast station in the 1970s. It was a clear, colorless liquid at room temperature but it had a very high vapor pressure and evaporated very rapidly. A common practical joke was to squirt it down somebody's neck when they were least expecting it. Karn (talk) 02:28, 4 June 2011 (UTC)[reply]

I just put in the redirect. I don't know why it wasn't there before. Gah4 (talk) 00:30, 23 August 2019 (UTC)[reply]

Plagiarism?

This article seems to have extensively borrowed language (in some cases, verbatim) from the following website: http://www.sfu.ca/~marshall/208web/cfcs.htm Also, gross scientific inaccuracies (see above) and generalizations make this a very poor wiki article. This article should be flagged for a rewrite according to wiki's quality standards. 66.188.132.196 (talk) 21:31, 19 September 2011 (UTC)[reply]

refrigerant?

The article indicates that it is used in refrigerators and air conditioners. It has a much higher boiling point than the Freons popular for refrigerators, and is (or was) popularly used as a cleaning solvent. I suppose it could be used in some high temperature refrigerators, but water is commonly used as a coolant at those temperatures. I think it is definitely too high for air conditioners.

It is also mentioned as an aerosol propellant. Maybe some who believe in global warming acceleration expected room temperature above 47.7C. A lot above, so maybe 60C for it to be a useful propellant. Maybe on venus or mercury for some space aliens. Gah4 (talk) 19:29, 12 July 2020 (UTC)[reply]

Thanks for finishing up removals that I missed. I am not sure about ozone depletion levels and times. I suspect that since it is heavier it takes longer to get up there, so will be around longer, but also lower depletion rate. Being used as a cleaning solvent, and not inside long lived refrigeration systems, I suspect it got out of use faster. Gah4 (talk) 22:00, 12 July 2020 (UTC)[reply]
