High-pressure liquid densities of fatty acid methyl esters: Measurement and prediction with PC-SAFT equation of state was written by Wang, Xiaopo;Kang, Kai;Zhu, Shanshan;Gao, Bo. And the article was included in Fluid Phase Equilibria in 2018.HPLC of Formula: 106-73-0 The following contents are mentioned in the article:
In this work, exptl. d. data were reported for six fatty acid Me esters, including Me butyrate, Me valerate, Me caproate, Me pelargonate, Me heptanoate, and Me caprylate. The densities were measured from 293.15K to 363.15K and pressures up to 60MPa by a vibrating-tube densimeter. The relative uncertainty of the measurement is estimated less than 0.001 with a confidence level of 0.95. The high pressure densities were correlated with a Tait-type equation. The overall average relative deviation between exptl. data and calculated results from Tait equation for the six fatty acid esters is 0.010%. The derived thermodn. properties, such as isobaric thermal expansivity and isothermal compressibility, were obtained from the exptl. d. results. Addnl., for the studied esters, the mol. parameters of the PC-SAFT equation of state were obtained based on the corresponding vapor pressures and liquid densities. The PC-SAFT equation was used to predict the high pressure densities of the esters, and good agreements were observed This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0HPLC of Formula: 106-73-0).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 106-73-0
