| description | The thermal parameters of the phase transitions and transport properties of tetra-n-butylammonium (TBA) perchlorate (n-C<sub>4</sub>H<sub>9</sub>)<sub>4</sub>NClO<sub>4</sub> (TBAClO<sub>4</sub>) were investigated. TBAClO<sub>4</sub> has a polymorphous transition at 330 K and melts at 487 K. The structure of the high-temperature (HT) phase belongs to cubic symmetry and is similar to the HT phases of TBABF<sub>4</sub> and TBAI salts. The conductivity parameters of the low-temperature and HT phases of TBAClO<sub>4</sub> were determined from the Arrhenius plots. The thermodynamic parameters and transport properties of TBAClO<sub>4</sub> were compared with those of other TBA salts having isostructural HT phases. The polymorphous phase transition entropy was found to correlate with the conductivity of HT phases of TBA salts; TBAClO<sub>4</sub> has the lowest conductivity compared to TBABF<sub>4</sub> and TBAI salts. |
