The freezing point of ethanol or ethyl alcohol (C2H6O) is around â114 Â°C; â173 Â°F; 159 K. The freezing point of methanol or methyl alcohol (CH3OH) is around â97.6 Â°C; â143.7 Â°F; 175.6 K. You'll find slightly different values for the freezing points depending on the source because the freezing point is affected by atmospheric pressure.
Too Hot to Handle. The peak flame temperature of ethanol is 1,920 degrees Celsius (3,488 degrees Fahrenheit), while the peak flame temperature of methanol is 1,870 degrees Celsius (3,398 degrees Fahrenheit). Ethanol also has a higher flash point than methanol: about at 14 degrees Celsius (57.2 degrees Fahrenheit) to methanol's 11-degree Celsius (51.8 degrees Fahrenheit) flash point. A volatile liquid's flash point is the lowest temperature at which it can vaporize to form an ignitable mixture in the area.
