Abstract
The heat capacity and the heats and temperatures of fusion of 1,3,5‐trimethylbenzene have been determined experimentally. This substance exhibits three melting points: at 228.424°K, at 223.346°K, and at 221.462°K. The only solid phase having reproducible heat capacities was found to be the one having the highest melting point. The entropy of the ideal gas at 25°C and one atmos pressure has been found to be 92.09±0.15 cal/deg mole.Keywords
