The Antoine equation is a class of semi-empirical correlations describing the relation between vapor pressure and temperature for pure substances. The Antoine equation is derived from the Clausius–Clapeyron relation. The equation was presented in 1888 by the French engineer Louis Charles Antoine (1825–1897). [1]
The Dortmund Data Bank [1] (short DDB) is a factual data bank for thermodynamic and thermophysical data. Its main usage is the data supply for process simulation where experimental data are the basis for the design, analysis, synthesis, and optimization of chemical processes.
For benzene with T c = 562.12 K [3] P c = 4898 kPa [3] T b = 353.15 K [4] ω = 0.2120 [5] ... Antoine equation; Tetens equation; Arden Buck equation; Goff–Gratch ...
VLE of the mixture of chloroform and methanol plus NRTL fit and extrapolation to different pressures. The non-random two-liquid model [1] (abbreviated NRTL model) is an activity coefficient model introduced by Renon and Prausnitz in 1968 that correlates the activity coefficients of a compound with its mole fractions in the liquid phase concerned.
Melting point: 5.5 C Water solubility: negligible Specific gravity: 0.87 Principal hazards *** Benzene is a carcinogen (cancer-causing agent). *** Very flammable. The pure material, and any solutions containing it, constitute a fire risk. Safe handling: Benzene should NOT be used at all unless no safer alternatives are available.
In the article, it is stated that the Antoine equation is derived from the Clausius–Clapeyron relation. However to my knowledge this is not possible, as the Antoine equation is semi empirical. The best one can do is derive the August equation, which holds when the specific volume in a substances initial phase is very small compared to its gas ...
In organic and physical organic chemistry, Clar's rule is an empirical rule that relates the chemical stability of a molecule to its aromaticity.It was introduced in 1972 by the Austrian organic chemist Erich Clar in his book The Aromatic Sextet.
Toluene (or methylbenzene) is a common chemical found in chemistry laboratories. An alkylbenzene is a chemical compound that contains a monocyclic aromatic ring attaching to one or more saturated hydrocarbon chains. [1] Alkylbenzenes are derivatives of benzene, in which one or more hydrogen atoms are replaced by alkyl groups.
