Temperature-dependent change in the thermal properties of the VRC-TAR system after 3-day annealing.
Annealing Temp. (°C) | M.P. (°C) | ΔHf (kJ/mol) |
---|---|---|
4 | − 1 | − 1 |
20 | 130.6 ± 5.0 | 32.5 ± 3.2 |
40 | 137.6 ± 0.5 | 49.6 ± 2.6 |
60 | 136.3 ± 2.1 | 42.5 ± 2.2 |
80 | 135.5 ± 1.7 | 36.5 ± 3.8 |
1 An annealing temperature of 4 °C produced a gel-like supercooled liquid for which the melting point and enthalpy could not be identified.
