Joback estimation formula

The normal boiling point is an easily accessible physical property and has been measured for a large number of substances. In case that it is not available, the normal boiling point can be estimated with group contribution methods, for example, Joback and Reid [4] and Constantinou and Gani [5], analogously to the estimation of the critical point. The estimation formula for the Joback method is... [Pg.72]

Joback s method is an improved version of earlier methods, and attempts to estimate many properties of all the organic compounds. Table 5.13 shows the recommended Joback coefficients to build up the boiling and melting points of a compound, according to the formula... [Pg.183]

The Joback method needs only the structural formula as input information except for the estimation of the critical temperature, where additionally the normal boiling point is required. In case it is unknown, it can be estimated with the Joback method as well. The Joback relationships are... [Pg.66]

For performing estimations, the group contribution method of Joback and Reid [4] can again be used. The corresponding formulas are... [Pg.77]
