ANTOINE COEFFICIENTS FOR VAPOR PRESSURE Iranian Chemical Engineers Website 91 cis‐1‐bromo‐1‐eicosene C20H39Br The Antoine equation is a mathematical expression (derived from the Clausius-Clapeyron relation) of the relation between the vapor pressure and the temperature of pure substances.

The equation was first proposed by Ch. Antoine, a French researcher, in The basic form of the equation is: and it can be transformed into this temperature-explicit form. A weighted least squares computation of the Antoine constants from vapor pressure data using a microcomputer.

Thanks for your answers. My question was mainly about the method that Aspen Plus applies in calculating the vapor pressure of the compounds in the case we are using an equation of state.

Obviously those aren't correct Antoint constants, and hopefully the users will be smart enough to recognize when those cases arise. I also noted a few compounds (1-hexadecene for example) where the tabulated Antoine constants are completely unreasonable and yield completely unreasonable values for the vapor pressure.

Vapor pressure (or vapour pressure in British English; see spelling differences) or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed equilibrium vapor pressure is an indication of a liquid's evaporation rate.

Alternatively, these are found in texts such as Reid et al. [6].Equation is only applicable for pressures ranging from 10 to mm Hg ( to 2 bar).

The Antoine equation should never be used outside the stated temperature limits, as extrapolation beyond these limits may lead to. The content of this database presents a compilation of results for vapor pressure using the Antoine equation, and contains an extensible, searchable table with Antoine coefficients of over 9, compounds.

The data is both experimentally determined and estimated based on methods developed by the author and other noted experts.

Vapor Pressure of by:   Antoine Coefficients And Vapor Pressure - posted in Student: Could somebody help me with finding Antoine coefficients and vapor pressure for some organic compounds. By help i mean the exact coefficient or title of a book or link or article, simply anything that will help me.

The main problem is that i have checked this page, a few books (like "The properties of gases and liquids" by Poling and.

Covering the properties of over 8, compounds, this volume, written by the world’s leading authority on chemical engineering, is more comprehensive and thorough than any other book of its kind. Antoine coefficients are one of the most important properties to industry processes, and Carl Yaws provides all the skills necessary for every Cited by: Predicting Vapor Pressure of Heavy Hydrocarbons from Molar Refraction and Its Applications to Petroleum Mixtures M.

Riazi* and Y. AlQaheem* Department of Chemical Engineering, Kuwait UniVersity, Kuwait In this paper a generalized relation based on the corresponding states approach and use of molar refraction is proposed for the estimation. The form of the Antoine equation used here is. log 10 (P) = A – [B / (T + C)], where P is the calculated vapor pressure in bar (on an absolute scale) and T is the temperature in Kelvin.

Using the below reference data assembled by NIST, you can plug in the values. You can compute the vapor pressure of compounds using the Antoine Equation, an emprical equation for vapor pressure: The constants for A, B, and C, are usually tabulated.

I use Perry's Chemical Engineers' Handbook to find them. This program permits to calculate the vapor pressure of solvent blends at different temperatures using the Antoine equations and Raoult's law for solvent blends.

The Antoine equation describes the relation between saturated vapor pressure and temperature of a pure component. In this work, a vapor pressure database 1 was critically checked and used in the fitting of Antoine coefficients for all the compounds studied (18 FAMEs and 6 FAEEs).

The Antoine equation is a vapor pressure equation and describes the relation between vapor pressure and temperature for pure components.
