Notes

Abstract: Experimental heat capacities (6-319 K) and enthalpy of sublimation, ∆subH˚ m(313.5K) = 87.52 ± 0.53 kJ mol-1, are reported for 2,4,6-trimethylbenzonitrile N-oxide. Heat capacity data show a reversible solid-phase transition in the 217-235 K temperature interval, for which the following thermodynamic functions have been computed: Ttr = 224.3 K; ∆trHm = 80 ± 4 J mol⁻¹; ∆trS = 0.35 ± 0.02 J mol⁻¹ K⁻¹. Thermodynamic properties of 2,4,6-trimethylbenzonitrile N-oxide in the condensed state are tabulated at every 5 or 10 K interval throughout the 0-320 K temperature interval.
