Talk:Dichlorodifluoromethane

Sources?
I notice the retrofit section describes how flushing of mineral oil is necessary before converting a refrigerant system from r-12 to r-134a. Are there any references for that requirement? I think it is misleading to say that mineral oil is not compatible with r-134a. They don't form any dangerous substances for the system when mixed, it's just that r-134a will not carry the mineral oil. It is not unheard of to just add ester oil to the system and leave the mineral oil in there to (harmlessly) sit. Also, I think it's prudent to mention which oil will need to be added to the retrofitted system (ester) and which oil absolutely cannot be added to the retrofitted system (PAG).

Triple point: "10 MPa (0.00010 bar)" These two measurements are not equal. A capital M means "mega" or 10^6.

.00010 bar = 10 Pascals 10 Megapascals = 100 bar —Preceding unsigned comment added by Kevinthenerd (talk • contribs) 21:24, 14 September 2007 (UTC)

Critical Temperature
I think the critical temperature is 112C not -112C

Also the densities are wrong

Dangers of inhalation?
Are there any dangers? —Preceding unsigned comment added by Lsuacner (talk • contribs) 12:58, 26 August 2008 (UTC) If it's burned and you inhale the vapor it's poisonous. I believe it makes phosgene gas. —Preceding unsigned comment added by Hondatech (talk • contribs) 07:31, 27 October 2008 (UTC) Very high concentrations (percent level) have been associated with cardiac effects, but there aren't really any data on inhalation exposure to lower concentrations.--Ashartus (talk) 16:40, 22 March 2010 (UTC)

The whole ozone hole thing is very controversial... A failed political scheme by Al Gore. It has been proven that volcanic activity has caused 99% of the so-called ozone depletion. Freon-12 is much safer than R-134a. 134a is flammable under pressure, and has been shown to cause testicular cancer with excessive or prolonged exposure. — Preceding unsigned comment added by 71.61.196.35 (talk) 08:35, 11 December 2011 (UTC)
