![عکس صفحه اول مقاله: Liquid–liquid equilibria of dipropylene glycol dimethyl ether and water by molecular dynamics Liquid–liquid equilibria of dipropylene glycol dimethyl ether and water by molecular dynamics](/preview/png/202457.png)
In the framework of the Industrial Fluid Properties Simulation Challenge 2010, liquid–liquid equilibria of dipropylene glycol dimethyl ether and water are determined by molecular dynamics simulation. A new force field for the ether was developed and combined with a water model from the literature (TIP4P/2005). According to the specifications of the competition, molar fractions of the components in the coexisting phases are predicted over a temperature range from 283 to 353 K.
► A new intramolecular force field for dipropylene glycol dimethyl ether (DPGDME) was parameterized with quantum mechanical data.
► The intermolecular interactions of DPGDME were fitted to experimental densities using the gradient based optimization workflow GROW.
► Simulations of water/DPGDME mixtures resulted in molar fractions quite close to the experimental LLE data.
