The solubilities of dimethyl ether (DME) in pentaerythritol tetrahexanoate (PEC6) and in pentaerythritol tetraoctanoate (PEC8) have been measured from (283.15 to 353.15) K based on the isochoric method. The expanded uncertainty (k = 2) of the measured solubility data was estimated to be less than 3.0 %. The experimental solubility data were correlated based on the Peng Robinson equation of state with Huron Vidal mixing rules and the NRTL equation for the excess Gibbs energy at infinite pressure. The absolute average deviation between experimental data and calculated values was 1.1 % and 1.0 % for DME + PEC6 system and DME + PEC8 system, respectively. The maximum absolute deviation was 2.93 % for the DME + PEC6 system and 2.90 % for DME + PEC8 system.
