Density, viscosity, and R1234yf Solubility in Dipentaerythritol Esters
Dipentaerythritol esters (DiPEs) are a class of polyol esters with six −COO– groups that can be used to adjust the viscosity of lubricants. However, data on the density and viscosity of DiPEs remain limited, and there are no reports available regarding the solubility of new alternative refrigerants in DiPEs. In the present study, the densities and viscosities of dipentaerythritol hexapentanoate (DiPEC5), dipentaerythritol hexaheptanoate (DiPEC7), and dipentaerythritol isononanoate (DiPEiC9) were measured at various temperatures and atmospheric pressure. To assess the compatibility of DiPEs with refrigerant 2,3,3,3-tetrafluoropropylene (R1234yf), the solubilities of R1234yf in DiPEC5, DiPEC7, and DiPEiC9 were measured from 283.15 to 343.15 K. The nonrandom two liquid (NRTL) activity coefficient model was used to correlate the solubility data. Furthermore, the solubilities of R1234yf in DiPEC5, DiPEC7, DiPEiC9, PEC5, PEC7, and PEC9 were compared.
期刊介绍:
The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
