Abstract
In this work, an experimental study for the determination of the density of two dipentaerythritol esters, dipentaerythritol hexapentanoate (DiPEC5) and dipentaerythritol hexaheptanoate (DiPEC7) has been performed for temperatures ranging from 283.15 K to 398.15 K and pressures up to 70 MPa. The heart of the automatic assembly is an Anton Paar DMA HPM vibrating-tube densimeter. The measured densities have been used to study the behaviour and influence of temperature and pressure on the isothermal compressibility, the isobaric thermal expansivity and the internal pressure.
