Automatized sspKa measurements of dihydrogen phosphate and Tris(hydroxymethyl) aminomethane in acetonitrile/water mixtures from 20 to 60 ºC
(Elsevier Science, 2014-09)
We measured pKa values of Tris(hydroxymethyl)aminomethane and dihydrogen phosphate; both are commonly used to prepare buffers for reverse-phase liquid chromatography (RPLC), in acetonitrile/water mixtures from 0% to 70% ...
Static dielectric constants of acetonitrile/water mixtures at different temperatures and debye-hückel A and a0B parameters for activity coefficients
(American Chemical Society, 2007-05)
Static dielectric constants of acetonitrile/water mixtures in the whole composition range and within the temperature range from (15 to 60) °C have been measured. The values were fitted to a unique equation as a simultaneous ...
Understanding the Influence of the Electrochemical Behavior of Potassium Hexacyanoferrate(II/III) on Acetonitrile/Water Binary Mixtures: An Experimental and Molecular Dynamics Study
(Amer Chemical Soc, 2018)
Microelectrode voltammetry was employed to gain information on the behavior of potassium hexacyanoferrate(II/III) in acetonitrile/water binary mixtures in order to understand the bulk properties of the mixture and the ...
Acid-base dissociation constants of o-phthalic acid in acetonitrile/water mixtures over the (15 to 50) °C temperature range and related thermodynamic quantities
(American Chemical Society, 2010-01)
Potassium hydrogen phthalate (KHP) is a primary titrimetric standard, and KHP solutions are also used as standards for pH reference values, in pure water or in hydrorganic solvent mixtures. However, the pH of these solutions ...
Polar mixtures under nanoconfinement
(American Chemical Society, 2009-09)
We present results from molecular dynamics simulations describing structural and dynamical characteristics of equimolar mixtures of water and acetonitrile, confined between two silica walls separated at interplate distances ...
δ conversion parameter between pH scales (WSpH and SSPH) in acetonitrile/water mixtures at various compositions and temperatures
(American Chemical Society, 2007-04)
The SSpH in acetonitrile/water mixtures at different temperatures cannot be directly measured because of the lack of calibration buffers in these hydroorganic media at most temperatures different from 25°C. In this paper, ...
Effect of temperature on the chromatographic retention of ionizable compounds: II. Acetonitrile–water mobile phases
(Elsevier Science, 2005-06)
The retentive behavior of weak acids and bases in reversed-phase liquid chromatography (RPLC) upon changes in column temperature has been theoretically and experimentally studied. The study focuses on examining the temperature ...
Changes in the SNAr reaction mechanism brought about by preferential solvation
(Royal Soc Chemistry, 2015)
We herein report an experimental and theoretical study on preferential solvation effects for the reactions of 1-fluoro and 1-chloro-2,4-dinitrobenzene towards morpholine in acetonitrile, water and mixtures of them of varying ...
