| Abstract: | The thermal properties including endothermal/exdothermal range and its capacity of normal alkane monomer and its mixture were investigated by differential scanning calorimetry. It has been proved that the thermal properties of normal alkane monomer is distinct from its mixture. The results show that the carbon number of normal alkane and its distribution have significant impacts on the thermal properties. The endothermal/exdothermal range and its capacity can be controlled by the content and variety of normal alkanes in paraffin. |
