The solubility of hydrogen sulfide and carbon dioxide in N‐octyl‐2‐pyrrolidone (NOP) was measured up to 1.4 MPa at 303 and 324 K using the static synthetic method. Experimental results were compared to those of the predictive Soave–Redlich–Kwong (PSRK) model, wherein the group interaction parameters for the NMP‐group (N‐methyl‐2‐pyrrolidone) were applied to the NOP systems. The reliability of the apparatus used and the applied data treatment were checked by comparing new experimental data for the system hydrogen sulfide+benzene at 304 and 324 K and pressures up to 1.2 MPa, and for the system hydrogen sulfide+methanol at 298 K and up to 0.4 MPa, with published data measured with the analytical method.
