EPA | TTN CHIEF | TANKS Software Frequently Asked Questions: "HOW DO I OBTAIN ANTOINE'S COEFFICIENTS FOR OTHER CHEMICAL COMPOUNDS?
Two of the best resources are the Handbook of Chemistry and Physics and Perry's Chemical Engineering Handbook. These references should be available at most technical libraries. Other references are:
Reid, Prausnitz and Sherwood, Properties of Liquids and Gases, McGraw Hill, 1987.
Yaws and Yang, Property Data: To Estimate Vapor Pressure Easily, Hydrocarbon Processing, October 1989.
Baublik, Fried and Hola, The Vapor Pressures of Pure Substances, Selected Values of the Temperature Dependent Vapor Pressure in the Normal and Low Pressure Regions, Elsevier Science Publishers, Amsterdam, 1984.
Antoine's Coeffecients are also in the NIST Chemistry workbook, which is available online at: http://webbook.nist.gov/chemistry/
**Please note that in some resources, such as the NIST Chemistry Workbook, the Antoine's equation constants in bar, K must be converted to mmHg, degrees C for use in TANKS 4.0. To do this, add 2.8751 to A, keep B the same, and add 273.15 to C."
