Abstract
The heat capacity and the heats and temperatures of fusion of 1,2,4‐trimethylbenzene have been determined experimentally. This substance exhibits two melting points: at 229.33±0.03°K and at about 224.2°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 99.59±0.15 cal/deg mole.Keywords
