Experimental measurements and a group additivity approach for estimating the standard molar enthalpies of formation of dioxins

Prediction of enthalpy and standard Gibbs energy of vaporization of haloaromatics from atomic properties

“…k The experimental vaporization properties were estimated from the sublimation ones derived from the original source, and from the results of the enthalpy and temperature of fusion (Rordorf, 1986), using the estimated value of D g l C o p;m = À82.1 J K À1 mol À1 . l The experimental vaporization properties were estimated from the sublimation ones derived from the original source, and from the results of the enthalpy and temperature of fusion (Kolesov et al, 1999), using the estimated value of D g l C o p;m = À86.8 J K À1 mol À1 . m The experimental vaporization properties were estimated from the sublimation ones derived from the original source, and from the results of the enthalpy and temperature of fusion (Rordorf, 1986), using the estimated value of D g l C o p;m = À91.5 J K À1 mol À1 .…”

Mechanisms for formation, chlorination, dechlorination and destruction of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs)

“…The enthalpy of formation of DF in the gas phase was measured by Shaub [ [217] (À11.9 AE 0.50 kcal/mol) using a rotating bomb calorimeter. This technique was also used by Kolesov et al [216] to obtain enthalpies of formation of 1-MCDD (À22.1 AE 4.8 kcal/mol), 2-MCDD (À17.7 AE 8 kcal/mol) and 2,3-dichlorodibenzo-p-dioxin (À26.7 AE 1.65 kcal/mol).…”

Experimental determination of the enthalpy of formation of dibenzo- p-dioxin

“…(1)(2)(3)(4)(5) All of them include the standard molar enthalpy of formation of unsubstituted dibenzo-p-dioxin f H o m (DD, g) as a base for further calculations. Therefore, it is necessary to have available the most reliable and precise value of f H o m (DD, g) in deriving such a set.…”
