The thermodynamic properties of methyldiallylsilane in the temperature range 4.7-335 K

The temperature dependence of the heat capacity of methyldiallylsilane in t he vitreous, supercooled liquid. and liquid states was studied in an adiaba tic vacuum calorimeter in the temperature range 4.7-335 K: the error of mea surements was similar to0.2%. The vitrification and vitreous state paramete rs were determined. The experimental data were used to calculate the C degr ees (p)(T), H degrees (T)- H degrees (0), S degrees (T)- S degrees (0), and G degrees (T)- H degrees (0) thermodynamic functions in the temperature ra nge 0-340 K. The standard entropy of formation of the compound fi om simple substances at 298.15 K was determined.
