Thermodynamic properties of tetraphenylantimony benzophenoxymate in the region of 0–450 K
摘要:
Heat capacity of tetraphenylantimony benzophenoxymate Ph(4)SbONCPh(2) is measured for first time using adiabatic calorimeter in the range from 6K to 350K and differential scanning calorimeter in the range from 330 K to 450 K. In the range of 400-450 K is revealed a melting accompanied with partial decomposition of the substance. Standard thermodynamic functions of crystalline Ph(4)SbONCPh(2) in the range from T -> 0 K to 440 K are calculated. Enthalpy of combustion of this compound is measured in a combustion calorimeter with isothermal cover and static bomb. Standard thermodynamic formation functions of crystalline Ph(4)SbONCPh(2) at 298.15 K are calculated. Fractal dimension D is revealed.
