Notes:
The vapor-liquid equilibria in the binary mixtures water-formaldehyde and methanol-formaldehyde are precisely correlated by introducing a physicochemical model that takes into account physical forces of interactions as well as chemical reactions. The most valuable feature of the model is its simple extension to multicomponent mixtures. From binary data alone the model is capable of accurately predicting vapor-liqid equilibria in complex mixtures such as formaldehyde-water-trioxane and formaldehyde-water-methanol. This is demonstrated by comparing calculated data with experimental results taken from the literature or measured in this work, at temperatures between about 310 and 400 K at pressures up to 500 kPa, and formaldehyde concentrations in the liquid phase of up to about 70 mol %.
