Аннотация:The low-temperature heat capacity of 4-nitro-4’-tert-butyl-diphenyl oxide was measured by vacuum adiabatic calorimetry in the temperature range (7 to 372) K. The temperature, the enthalpy and the entropy of fusion and the temperature, the jump of the heat capacity, and the range of devitrification of glass-transition were determined. Heat capacity and main thermodynamic functions (changes of entropy, enthalpy, and Gibbs energy) in condensed state are tabulated as a function of temperature from 5 to 370 K. The entropy of formation at T = 298.15 K of 4-nitro-4’-tert-butyl-diphenyl oxide in crystal state was computed on the basis of the obtained experimental data.
