Antoine equation![]() Clausius-Clapeyron equation ![]() enthalpy of sublimation ![]() enthalpy of vaporization ![]() ideal gas law constant ![]() vapor pressure ![]() |
Chemical engineers sometimes need more more reliable vapor pressure estimates. The Antoine equation is a simple 3-parameter fit to experimental vapor pressures measured over a restricted temperature range:
log P = A - | B T + C |
Antoine coefficients for many substances are tabulated in Lange's Handbook of Chemistry (12th ed., McGraw-Hill, New York, 1979) and they are available online from NIST's Chemistry WebBook. The following books, CD's, and Web sites give parameters and further information about the Antoine equation:
