Study of association of 2-methoxyethanol in the aqueous phase

Abstract.

 Monte Carlo simulations have been carried out for 2-methoxyethanol in an isothermal–isobaric ensemble (NPT) at 298.15 K and 1 atm pressure. The optimized potential for liquid simulation force field parameters has been used for modeling 2-methoxyethanol and the TIP4P model for water. Intramolecular rotations are described by an analytical potential function fitted to ab initio energies. It has been shown that the water molecules can form hydrogen bonds between adjacent O atoms of CH₃OCH₂CH₂OH in aqueous media. The self-association of 2-methoxyethanol in aqueous media has been studied by statistical perturbation theory.
