Thermodynamics of SO2 Dissolution in N,N-Dimethylformamide, Dimethylsulfoxide, N,N-Dimethylacetamide, and Tributyl Phosphate at 295.15–323.15 K

Resumo

Based on the solubility of sulfur dioxide in N,N-dimethylformamide, dimethylsulfoxide, N,N-dimethylacetamide, and tributyl phosphate, with temperature ranging from 295.15 to 323.15 K, some thermodynamic functions of the dissolution process such as enthalpy and entropy were calculated. The solubility data are compared with dipole moments and dielectric permittivity of the solvents. The obtained data are helpful for the removal of sulfur dioxide in industrial processes.
