Both DME and DMP are united-atom models compatible with GROMOS\/OPLS force fields. Calculated thermodynamic and structural properties of the pure DME and DMP liquids resulted in excellent agreement with the experimental data. In aqueous solutions, densities, diffusion coefficients, and concentration dependent conformers of DME, were in agreement with experimental data. The calculated free energy of solvation (\u0394Ghyd) at 298 K is equal to \u201322.1 \u00b1 0.8 kJ mol\u22121 in good agreement with the experimental value of 20.2 kJ mol\u22121. In addition, the free energy of solvation of DME in non-aqueous solvents follows the trend methanol \u2248 water &amp;lt; carbon tetrachloride &amp;lt; n-heptane, consistently with the dielectric constant of the solvents. On contrary, the presence of an extra methyl group on chiral carbon makes DMP less soluble than DME in water (\u0394Ghyd = \u221216.0 \u00b1 1.1 kJ mol\u22121) but more soluble in non-polar solvents as n-heptane. Finally, for the DMP the chiral discrimination of the two enantiomers was calculated as solvation free energy difference of one DMP isomer in the solution of the other. The obtained value of \u0394\u0394GRS = \u20133.7 \u00b1 1.4 kJ mol\u22121 indicates a net chiral discrimination of the two enantiomers.<\/jats:p>","DOI":"10.1063\/1.3643417","type":"journal-article","created":{"date-parts":[[2011,10,24]],"date-time":"2011-10-24T22:24:38Z","timestamp":1319495078000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":39,"title":["Structure and dynamics of 1,2-dimethoxyethane and 1,2-dimethoxypropane in aqueous and non-aqueous solutions: A molecular dynamics study"],"prefix":"10.1063","volume":"135","author":[{"given":"Samira","family":"Hezaveh","sequence":"first","affiliation":[{"name":"Jacobs University Bremen 1 School of Engineering and Science, , Campus Ring 1, D-28759 Bremen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susruta","family":"Samanta","sequence":"additional","affiliation":[{"name":"Jacobs University Bremen 1 School of Engineering and Science, , Campus Ring 1, D-28759 Bremen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuseppe","family":"Milano","sequence":"additional","affiliation":[{"name":"University of Salerno 2 Department of Chemistry, , I-84084, Fisciano (Salerno), Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danilo","family":"Roccatano","sequence":"additional","affiliation":[{"name":"Jacobs University Bremen 1 School of Engineering and Science, , Campus Ring 1, D-28759 Bremen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2011,10,24]]},"reference":[{"key":"2023062002584105700_c1","doi-asserted-by":"publisher","first-page":"159","DOI":"10.1016\/S0167-2738(00)00723-2","volume":"134","year":"2000","journal-title":"Solid State Ionics"},{"key":"2023062002584105700_c2","doi-asserted-by":"publisher","first-page":"3844","DOI":"10.1021\/ic00118a041","volume":"34","year":"1995","journal-title":"Inorg.
