Abstract:

A method of fitting vapor pressure temperature data to the Antoine equation is described along with a detailed statistical analysis of the fits and calculations of vapor pressures, enthalpies of vaporization, volatilities concentration of saturated vapors, and boiling points with the Antoine constants. It is shown that the number of digits required to accurately perform vapor pressure calculations is greater than previously believed. The system permits calculation of the limits of error for any level of confidence. A program is used to analyze and plot the available vapor pressure data for diethyl malonate. Vapor pressure, Antoine equation, Volatility, Temperature, Statistics, Plotting, Enthalpy of Vaporization, Concentration of saturated vapor, Experimental methods, Diethyl malonate, Confidence limits, Confidence level.
