In the present research, the temperature dependence of heat capacity Cp,m∘=f(T) of NEOPENTYLBENZENE (cas 1007-26-7) C6H5–C5H11 has been measured between T = (6 and 350) K in the precision adiabatic vacuum calorimeter and reported for the first time. The temperature and enthalpy of fusion of neopentylbenzene and the total mole fraction of impurities have been determined. The experimental results have been used to calculate the standard (р° = 0.1 MPa) thermodynamic functions Cp,m∘/R,Δ0THm∘/RT,Δ0TSm∘/R and Φm∘/R=Δ0TSm∘/R-Δ0THm∘/RT (where R is the universal gas constant) of neopentylbenzene over the range from T → (0 to 350) K. The standard entropy of formation of the compound under study at T = 298.15 K has been calculated.
