“…The vapor pressure is correlated with the Antoine equation , ln ( p normals / normalk normalP normala ) = A − B T / K + C where p s (kPa) is the vapor pressure; T (K) is the absolute temperature; and A , B , and C are Antoine constants, which are adjustable parameters of the characteristic substances characteristic. The parameters A , B , and C were evaluated from the experimental data by the global optimization algorithm using the First Optimization (1stOpt) software.…”

The density and the heat capacity of (E,E)-methyl sorbate (MS) were measured from 286.35 to 433.25 K using a pycnometer and an adiabatic calorimeter, respectively. The saturated vapor pressure of MS was determined by the ebulliometric method from 344.95 to 455.15 K and correlated by the Antoine equation with an average relative deviation of 1.68%. The enthalpy of vaporization of MS at the normal boiling point was figured out to be 44.29 kJ mol −1 according to the Clausius− Clapeyron equation. Based on the Othmer method, the standard enthalpy of vaporization of MS was obtained using three substances as a reference, and the calculated results were further verified by the Watson relation and the Clarke−Glew equation.

Developing diesel surrogates that mimic the essential characteristics of target fuels such as their sooting tendency and volatility is a necessary but challenging endeavor, owing in part to the scarcity of available experimental sooting data for compounds in the appropriate high molecular weight range. To address this, in this work we demonstrate an experimental approach which provides quantitative sooting data for such compounds. Speci cally, we have measured spatially resolved two-dimensional soot volume fraction distributions for three large hydrocarbons: , ,-triisopropylbenzene (), , ,-triisopropylcyclohexane (), and perhydrophenanthrene (), as well as benzene and n-hexane. Measurements were performed in methane/air co owing ames whose fuel was doped separately with these compounds (dopant mass fraction .). Color-ratio pyrometry was used to measure soot temperature and soot volume fraction distributions. Sooting tendencies were > benzene > > > hexane. ese data are expected to be useful in formulation of surrogates with greater delity to the volatility and sooting characteristics of real diesel, and in validation of numerical soot models involving such surrogates.

The second part of this compendium concludes with a collection of phase change enthalpies of organic molecules inclusive of C11–C192 reported over the period 1880–2015. Also included are phase change enthalpies including fusion, vaporization, and sublimation enthalpies for organometallic, ionic liquids, and a few inorganic compounds. Paper I of this compendium, published separately, includes organic compounds from C1 to C10 and describes a group additivity method for evaluating solid, liquid, and gas phase heat capacities as well as temperature adjustments of phase changes. Paper II of this compendium also includes an updated version of a group additivity method for evaluating total phase change entropies which together with the fusion temperature can be useful in estimating total phase change enthalpies. Other uses include application in identifying potential substances that either form liquid or plastic crystals or exhibit additional phase changes such as undetected solid–solid transitions or behave anisotropically in the liquid state.
