abstract = "In this paper we propose a framework for Model-based Sequential Optimal Design of
Experiments to assist experimenters involved in Vapor-Liquid equilibrium characterization studies to
systematically construct thermodynamically consistent models. The approach uses an initial
continuous optimal design obtained via semidefinite programming, and then iterates between two
stages (i) model fitting using the information available; and (ii) identification of the next
experiment, so that the information content in data is maximized. The procedure stops when the
number of experiments reaches the maximum for the experimental program or the dissimilarity between
the parameter estimates during two consecutive iterations is below a given threshold. This
methodology is exemplified with the D-optimal design of isobaric experiments, for characterizing
binary mixtures using the NRTL and UNIQUAC thermodynamic models for liquid phase. Significant
reductions of the confidence regions for the parameters are achieved compared with experimental
plans where the observations are uniformly distributed over the domain.",
