Liquid–vapour equilibria of the methyl esters of alkanoic acids: vapour pressures as a function of temperature and standard thermodynamic function changes
Abstract:The vapour pressures as a function of temperature of the methyl esters of alkanoic acids from butanoic to eicosanoic acid, have been measured using two different techniques: the static diaphragm and spinning rotor manometry and the combined torsion mass-loss effusion. Combined with data available from literature, the new data have been processed using the thermodynamic regression equation proposed by Clarke and Glew. The results of this research are reliable vapour pressures and the thermodynamic properties of… Show more
“…As observed in Table 2, the DOP vapor pressure reported by Gobble et al (2014) is in good agreement with our result, within experimental error. Also the mono-esters FAME 16:0 and 18:0 correlated well with the bibliographic data (van Genderen et al, 2002;Chickos et al, 2004).…”

“…From the bibliographic data available of K OA , two members of the ubiquitous and widely used phthalate's family (Staples, 2003), BBP and DOP, have shown a different behavior. On the one hand, the log K OA = 8.7 for BBP reported by van Genderen et al (2002), did not correlate well with the standard calibration curve. Therefore, its experimental measure had been taken as unknown value (empty triangle in Figure N°S5.1) and the present result suggests a more accurate value of log K OA = 9.12 ± 0.56.…”

“…The pure compounds data to be regressed were taken from the DIPPR database [31] at regularly spaced intervals in the whole range of temperature [0.4T c -T c ] and also from van Genderen et al [32]. Only the data considered as acceptable by DIPPR were used in this work.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
