Key words: carbon dioxide, N-isopropylacrilamide, solubility, solubility isotherms, phase equilibrium, Chrastil’s model.
Solubility isotherms of N-isopropylacrylamide (NIPAM), obtained via visual synthetic method at temperatures 304.8—353.0 K and pressures 0.1—40.0 MPa, are reported in the current paper. The maximal solubility of NIPAM within this range of parameters is determined as well. The crossover region in regards to the P mix = ƒ (x, mol. %) isotherms is located and the nature of the phenomenon is discussed further. Predictive ability of the Chrastil’s model is evaluated in relation to the NIPAM-CO2 system.
