The thermal behaviors of binary mixture formed from hydrogen bonded nematic liquid crystals 4-hexylbenzoic acid and 4-(octyloxy) benzoic acid, were investigated by differential scanning calorimetry (DSC). The phase transition temperatures and enthalpies were determined by using calorimetric methods on DSC. The DSC results clearly indicate that the produced liquid crystal mixture displays liquid crystalline properties. The phase transition temperature values increase with increasing heating rate between 5 degrees C/min and 20 degrees C/min, and the calculated activation energy values show that the reaction arising during the phase transitions of the mixture is regular.
