MiscibilitydataLiquid–liquidPhasediagramDeuteriumIsotopeAcetonitrileWaterThe miscibility of four binary liquid mixtures containing acetonitrile (ACN, ACN-d3) and water (H2O, D2O) has been studied. All the measured systems present solubility curves characterized by slight asymmetry and the presence of an ...
Acetonitrile is an aliphatic nitrile and transparent to UV-visible light. This allows acetonitrile to be useful for spectrophotometric monitoring techniques. It also has a low viscosity, high elution strength and miscibility in water. Some properties of acetonitrile: Molecular weight: 41.05 g/mol Exact...
Acetonitrile has always been considered the best performing organic modifier for RPLC applications, due to its chemical features (complete miscibility in water, UV transparency, low viscosity etc); nevertheless, it suffers of severe shortcomings, and most importantly, it does not fully comply with ...
point, little miscibility with water and not forming an azeotrope with acetonitrile by (1) distilling off fractions volatile up to about 76 C., (2) distilling water from the residue using an entraining agent and (3) recovering pure acetonitrile by fractional distillation of the resulting residue...
Pure acetonitrile is recovered from aqueous acetonitrile by extracting with an organic solvent which has little miscibility with water, boils higher than acetonitrile and does not form an azeotrope with acetonitrile. The portion of the extract boiling up to 76 DEG C is distilled off. The remaining...

In addition, a spectroscopic dilution correction procedure was developed to compensate for any miscibility of oil samples with acetonitrile, and gap-segment 2nd derivative spectra were employed to minimise the associated possibility of spectral interferences from absorptions of the oils. In comprehensive ...
Preferential uptake of water by the columns can be described by Langmuir isotherms. Even though a diffuse rather than a compact adsorbed discrete layer of water on the adsorbent surface can be formed because of the unlimited miscibility of water with acetonitrile, for convenience, the preferentially...
