An alternative approach was implemented to address the lack of readily available experimental vapor-liquid equilibrium data for the remaining components of the fragrant mixture (limonene, geraniol, and vanillin). Given the challenges in sourcing tabulated data, we em- ployed a different methodology. Instead of evaluating the saturation temperature residual distribution, we used an estimate of the saturation temperature standard deviation. This estimate was obtained from the reported root mean squared errors (RMSEs) in .
