Heat capacity measurements between 293 K and 363 K have been carried out in order to elucidate the different states appearing
in 2-amino-2-methyl-1,3 propanediol (AMP) plastic crystal. The results allowed one of them to be identified as a glassy crystal.
The changes of enthalpy, entropy and Gibbs free energy thermodynamic functions with temperature have been calculated from
the experimental heat capacity values.
