[Display omitted] •Volume change of CO2 + long-chain liquid n-alkane (with n ≥ 14) mixtures were studied.•Abrupt changes in volume expansion were observed near the CO2 critical point.•The abrupt due to the critical anomaly of the thermodynamic behavior of the mixture.•Machine learning (ML) were used...
