The pρT behaviour of the lactate family

The densities of methyl lactate, ethyl lactate and butyl lactate have been measured using a high-pressure, high-temperature vibrating tube densimeter system over a temperature range from T = (283.15 to 338.15) K and a pressure range from p = (0.1 to 60.0) MPa. The experimental densities have been satisfactorily correlated with temperature and pressure using the TRIDEN equation. Finally, from the experimental densities, properties such as isobaric expansibility and isothermal compressibility have been calculated.

► PrhoT behaviour of three lactates are reported.
► The experimental results have been compared with the available literature data.
► TRIDENT model has been used to correlate experimental data of the compounds.
► Derived properties have been calculated from densities using Tait equation.
