Popis: Heat capacity of tetraphenylantimony benzophenoxymate Ph4SbONCPh2 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 Ph4SbONCPh2 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 Ph4SbONCPh2 at 298.15 K are calculated. Fractal dimension D is revealed.
