ironizer Posted March 11, 2006 Share Posted March 11, 2006 I've searched all over the place, and i can't find it. So does anyone know what the flame temperature of isopropyl (rubbing) alcohol is? P.S. Doesn't matter if it's 70%, 99%, or 100% Link to comment Share on other sites More sharing options...
RyanJ Posted March 11, 2006 Share Posted March 11, 2006 Here is the quation for the reactioN: [ce]2C3H7OH + 13O2 -> 6CO2 + 8H2O[/ce] Work out the [math]\Delta H[/math] and you have your answer Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
ironizer Posted March 13, 2006 Author Share Posted March 13, 2006 I was looking for an answer in degrees, because i suck at chem. forumula calculation stuff Link to comment Share on other sites More sharing options...
Darkblade48 Posted March 13, 2006 Share Posted March 13, 2006 Wouldn't the flame temperature be dependent on the portion of the flame you are measuring (i.e. base of flame vs. tip of flame) and the amount of air/fuel ratio you have as well (i.e. lots of oxygen for a little bit of alcohol vs. minimal oxygen for a large volume of alcohol)?

ironizer Posted March 15, 2006 Author Share Posted March 15, 2006 just spraying some and burning it in regular air. I just wanna have a general idea, don't need anything exact. I just want to know if it's chemically possible to melt something with it, so a variation of +/- 50-100 degrees C won't do any harm. Link to comment Share on other sites More sharing options...
Immunologist Posted March 15, 2006 Share Posted March 15, 2006 At 99%, it is 53 celsius deg http://www.sigmaaldrich.com/cgi-bin/hsrun/Suite7/Suite/HAHTpage/Suite.HsSigmaAdvancedSearch.formAction'>http://www.sigmaaldrich.com/cgi-bin/hsrun/Suite7/Suite/HAHTpage/Suite.HsSigmaAdvancedSearch.formAction When looking for such info, look at the MSDS of the product, it is the Material Safety Data Sheet, delivered by producers of the product. Sigma-Aldrich produces almost anything (http://www.sigmaaldrich.com) Good Luck! Link to comment Share on other sites More sharing options...
woelen Posted March 15, 2006 Share Posted March 15, 2006 You cannot simply tell the flame temperature of any burning chemical. If you simply light some liquid, or when it is sprayed out into the air from a burner, there can be quite different temperatures. A nice example is the gas stove. The blue flames have a totally different temperature than the orange flames. So, it depends on how it is burnt. However, in any case, the temperature will be at least a few hundreds of degrees Centigrade. Link to comment Share on other sites More sharing options...
YT2095 Posted March 15, 2006 Share Posted March 15, 2006 the only really accurate thing you could determine with this alc would be with a bomb calorimeter to find the energy value of combustion. Link to comment Share on other sites More sharing options...
ironizer Posted March 16, 2006 Author Share Posted March 16, 2006 well, i saw those stats. that say for example gasoline can burn at 2400 degrees max, and natural gas like 3000 or something, because every flamable thing has a limit on high the temperature can get, i mean you can't make a 5000 degree fire with wood for example. I'm aware that the temp. depends on a lot of things like oxygen etc. but if isopropyl burns at around 50 C, dang, that's not even enough to make you say ouch Link to comment Share on other sites More sharing options...
