Measurements of the vapor-liquid equilibrium in the system formaldehyde + water + butynediol were performed at 393 K and 413 K for overall formaldehyde mass fractions between 0.1gg-1 and 0.2gg-1 and overall butynediol mass fractions between 0.05gg-1 and 0.35gg-1. The studied system is a complex reactive multicomponent mixture as formaldehyde reacts both with formaldehyde and butynediol. A predictive physico-chemical model of the vapor-liquid equilibrium from the literature [1] is validated by the experiments of the present work. Residue curves are calculated to illustrate the distillation behavior of the studied system.
