Dominant Association Species in Binary Mixtures of Methanol, Ethanol and Propanol in Nonpolar Solvents
The molecular associations in the binary mixtures of (methanol/solvent), (ethanol/solvent) and (propanol/solvent) were studied using NMR, FTIR and VLE data at different temperatures. The activity coefficients as the most important quantities representing the mixture deviation form ideal behavior were evaluated by using various association models to express the physical and chemical contribution...
متن کاملCalculated Infrared Spectra of Hydrogen-Bonded Methanol–Water, Water–Methanol, and Methanol–Methanol Complexes
Ab initio calculations at the B3LYP/aug-cc-pVDZ, B3PW91/aug-ccpVDZ, MP2/aug-cc-pVDZ, B3LYP/6-311 G(2d,2p), B3PW91/6-311 G(2d,2p), and MP2/6-311 G(2d,2p) levels are performed for the IR spectra of isolated water and methanol molecules and hydrogen-bonded water–methanol, methanol–water, and methanol–methanol complexes. Frequency shifts and changes in intensities are obtained for the proton donor ...
متن کاملDroplet Dynamics Changes in Electrostatic Sprays of Methanol-Water Mixtures
Two-dimensional phase Doppler anemometry measurements have been carried out to determine the size and velocity distributions of electrosprayed droplets generated from methanol-water mixtures. We investigated spraying conditions close to those of electrospray ionization sources. The droplet size and the axial and radial velocity distributions were measured as a function of liquid flow rate, need...
متن کاملColloidal Dispersion of a Perfluorosulfonated Ionomer in Water–Methanol Mixtures
We have investigated the dispersion state of a perfluorosulfonated ionomer (PFSI; Nafion®) in aqueous dispersion and the effect of methanol (MeOH) added to the aqueous dispersion by small-angle X-ray scattering (SAXS) as well as static and dynamic light scattering (SLS and DLS, respectively). Although both electrostatic and hydrophobic interactions of PFSI are expected to be strong in the dispe...
متن کاملSolvation Phenomena of Potassium Thiocyanate in Methanol–Water Mixtures
This paper reports the results of a variety of experiments carried out for understanding the solvation behavior of potassium thiocyanate in methanol–water mixtures. Electrical conductivity, speed of sound, viscosity, and FT-Raman spectra of potassium thiocyanate solutions in 5 and 10% methanol–water (w/w) mixtures were measured as functions of concentration and temperature. The conductivity and...
