ABSTRACT
New experimental results for the vapor-liquid equilibrium of the binary system (trioxane + water) at 393 K and 413 K and the ternary system (formaldehyde + trioxane + water) at 413 K and around 450 kPa are reported and compared with predictions/correlations using a physicochemical model combining the UNIFAC equation for the Gibbs excess energy with chemical reaction equilibria. Revised parameters of the model for these systems are reported.
