Thermodynamics of dissolution of thiourea in triethylene glycol

Resumo

The solubility of thiourea in triethylene glycol was determined in the temperature range of 318.35–357.75 K. The experimental data were approximated by the modified Apelblat equation. The dissolution enthalpy and dissolution entropy were calculated from the experimental data. The mutual interactions between solvent and solute were discussed in brief. The obtained data may be useful for development of the processes involving thiourea.
