400C is good, you never really need more than that. My Corning hotplate/stirrer claims to reach 500C, but I doubt that.
For a propane torch, you can expect a flame temperature between 1800-1950C, and I think the maximum is about 2000C. Butane is comparable.
Bunsen burners are usually methane (natural gas), and have similar flame temperatures as propane.
MAPP gas torches can go a bit hotter than propane, I think they burn just above 2000C in air.
These figures were if the fuel was burning in just air. Oxygen boosts the temperatures way higher. Oxy-acetylene torches burn at 3100C. This is
compared to air-acetylene which burns at 2400C.
Dicyanoacetylene, N≡C-C≡C-C≡N, burns in oxygen at 4990C!
Needless to say, this compound is quite reactive.
Do you have a torch, Acetic? I have a propane torch, and a MAPP/propane oxy-torch. I also have a tank of argon for welding purposes and as an inert
gas. |
