Table of coefficients of Antoine Equation for pure compounds. Still further, by keeping the water vapor above, but not substantially above, 7% by weight of the butyraldehyde vapor at the top of the column, for example, between about 7% and 15%, specifically, about 10%, a relatively small proportion of the methanol passes over as a vapor with the butyraldehyde and, hence, a large part of the methanol may be recovered free of aldehyde from the tailings. Critical Properties and Vapor Pressure. Vapor pressure is dependent upon temperature. Excess enthalpies, and vapor-liquid equilibrium and surface properties of the highly non-ideal associated mixtures formed by an alcohol and propanal. Vapour pressure, pressure exerted by a vapour when the vapour is in equilibrium with the liquid or solid form, or both, of the same substance—i.e., when conditions are such that the substance can exist in both or in all three phases.Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature.
