Chapter 3. Regression and Correlation of Data
Estimation of Antoine Equation Parameters Using Nonlinear Regression
Direct use of the Antoine equation to correlate vapor pressure versus temperature data.
Numerical Methods Utilized
Nonlinear regression of a general algebraic expression with determination of the overall variance and confidence intervals of individual parameters.
Excel Options and Functions Demonstrated
The Antoine equation is a widely used vapor pressure correlation that utilizes three parameters, A, B, and C. It is often expressed by
where Pv is the vapor pressure in mm Hg and T is the temperature in °C. ...
