Abstract

A vibrating-tube densimeter has been used to measure compressed-liquid densities of the fluids pentaerythritol tetrapentanoate (PEC5), pentaerythritol tetraheptanoate (PEC7), pentaerythritol tetranonanoate (PEC9), and a commercial lubricant, Royco 899 from 270 K to 470 K at pressures from 0.5 MPa to 50 MPa. The data have been extrapolated to atmospheric pressure and correlated with a Racket equation and the compressed-liquid density data have been correlated to Tait equations for comparison to existing literature data.
