Liquid Structure of 1-Butyl-3-methylimidazolium Hexafluorophosphate by Neutron Diffraction with H/D Isotopic Substitution Method

Liquid structure of 1-butyl-3-methylimidazolium hexafluorophosphate by neutron diffraction with H/D isotopic substitution method.

The liquid structure of the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate, [BMIM]PF(6), was investigated by neutron diffraction with H/D substitution method, where the hydrogen atoms in the imidazolium ring were partially deuterated. The local structures around the ring hydrogen atoms in liquid are very similar to those estimated from the crystal structure.

Uultra-trace determination of cadmium (II) in aqueous environmental samples by a new ion selective electrode based on nefazodone and 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid

Background and Objective: Cadmium is a potential environmental contaminant that causes adverse effects on the environment and the health of living organisms. Therefore, designing a simple and economic technique for its determination is very important. In this respect, a potentiometric sensor based on nefazodone as the ionophore and [BMIM]PF6 as the ionic additive were developed for the determin...

elucidation of chemical structure of wood lignin by dissolving in 1-butyl-3-methylimidazolium chloride ionic liquid

residual lignin of wood after mwl isolation was dissolved with 1-butyl-3-methylimidazolium chloride ionic liquid. chemical structure of isolated mwl from poplar wood (popolus deltiodes) and dissolved residual lignin were characterized with gas chromatography and 1d, 2d nmr techniques. analytical results showed that  popolus deltoides wood has more 4-(3-hydroxy-1-propenyl)-2-methoxy phenol units...

Transport properties of binary mixtures of carbon dioxide and 1-butyl-3-methylimidazolium hexafluorophosphate studied by transient grating spectroscopy.

Transient grating spectroscopy was applied to measurements of sound velocity and thermal diffusivity in binary mixture solutions of carbon dioxide (CO(2)) and 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF(6)]) along the saturated line of CO(2) at 40 degrees C up to 20.0 MPa. The sound velocity decreased more than 10% by increasing the pressure to 10 MPa, and the pressure effect was...
