The thermodynamic functions of trimethylsilylethyleneimine in the temperature range 0-310 K

The temperature dependence of the heat capacity of trimethylsilylethyleneim ine was determined accurate to similar to 0.2% in the temperature range 5-3 10 K with the use of an adiabatic vacuum calorimeter. The temperature and t he enthalpy of fusion of the substance were determined. The experimental da ta were used to calculate the thermodynamic functions in the temperature ra nge 0-310 K. The isochoric heat capacity and its lattice and atomic compone nts were estimated.
