Webb30 jan. 2004 · We have used a static method to measure vapor pressures of propylene carbonate (C 4 H 6 O 3) and N, N -dimethylacetamide (C 4 H 9 NO). Measurements for propylene carbonate were made over the temperature range from (298.15 to 473.15) K; pressures ranged from (0.003 to 37.76) kPa. WebbThe enthalpy of vaporization(symbol ∆Hvap), also known as the (latent) heat of vaporizationor heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas. The enthalpy of vaporization is a function of the pressureat which that transformation takes place.
