Observation of equilibrium liquid-liquid transition in triphenyl phosphite

- The equilibrium liquid-liquid transition of triphenyl phosphite was detected by DSC.
- The temperature of the LLT from glacial phase to supercooled liquid is 241.7 K.
- LLT enthalpy and entropy are 12.0 kJ mol−1 and 49.5 J K−1 mol−1, respectively.
- The glacial phase has much smaller residual entropy than the glassy liquid.
