A group contribution method for normal boiling point estimations was developed using a data base of 4426 diverse organic compounds. With this data set, boiling point predictions had a average absolute error of 15.5 K corresponding to a 3.2 average percent error. For a data set of 6584 other compounds, not used in deriving the method, the average absolute error was 20.4 K with a 4.3 average percent error. A vapor pressure equation was tested and used to extrapolate boiling points measured at reduced pressure. Thus this method may also be used to predict vapor pressures. [ABSTRACT FROM AUTHOR] |
