Extraction of PCBs and water from river sediment using liquefied dimethyl ether as an extractant.

Kazuyuki Oshita et al.

Chemosphere, 78(9), 1148-1154 (2010-01-02)

We investigated whether polychlorinated biphenyls (PCBs) and water could be simultaneously removed from river sediment by solvent extraction using liquefied dimethyl ether (DME) as the extractant. DME exists in a gaseous state at normal temperature and pressure and can dissolve

Molecular dynamics study of Acid-catalyzed hydrolysis of dimethyl ether in aqueous solution.

Xiao Liang et al.

The journal of physical chemistry. B, 115(25), 8199-8206 (2011-06-10)

The acid-catalyzed hydrolysis of dimethyl ether (DME) to methanol was examined using ab initio density functional metadynamics simulations. Diffusion of the acid proton from the aqueous medium, leading to the formation of a protonated DME, is 12.3 kcal mol(-1) activated

Theoretical investigation of the interaction between fluorinated dimethyl ethers (nF = 1-5) and water: role of the acidity and basicity on the competition between OH...O and CH...O hydrogen bonds.

Salma Parveen et al.

The journal of physical chemistry. A, 113(21), 6182-6191 (2009-05-09)

Theoretical calculations have been carried out using ab initio MP2 and B3LYP density functional methods to investigate the interaction between fluorinated dimethyl ethers (nF = 1-5) and water. Depending on the number of F atoms implanted on the dimethyl ethers
