Thermodynamic properties of
nitro derivatives of diphenyl ether and biphenyl
Abstract
The heat
capacity of 4,4¢-dinitrodiphenyl ether and 4-nitro-4¢-biphenylcarboxylic
acid were measured by adiabatic calorimetry (AC) in the ranges of temperature
8–372 K and 10– 372 K, respectively. The heat capacity of 4,4¢-dinitrodiphenyl ether
in the temperature range 323– 500 K, the thermodynamic properties of
fusion, and the purity of the ether were measured by differential scanning
calorimetry (DSC). The main thermodynamic functions in the range 5–370 K of
temperature were calculated for the both compounds using the heat capacities of
adiabatic calorimetry. Related thermodynamic functions of 4,4¢-dinitrodiphenyl ether
in the temperature range 370–500 K were calculated on the basis of DSC data.
