Morphology of polysorbate 80 (Tween 80) micelles in aqueous dimethyl sulfoxide solutions

The structures of micelles of the surfactant polysorbate 80 (Tween 80) in 0-50% aqueous dimethyl sulfoxide (DMSO) solutions (pH 7.2, ionic strength 2.44 mM) were investigated by means of small-angle X-ray scattering. At DMSO concentrations of 0-20%, core-shell cylinder micelles formed, and at 30-50% DMSO, core-shell discus micelles formed, that is, changing the hydrophobicity of the DMSO solven...

Preferential solvation and ion association properties in aqueous dimethyl sulfoxide solutions.

We study the solvation and the association properties of ion pairs in aqueous dimethyl sulfoxide (DMSO) solution by atomistic molecular dynamics (MD) simulations. The ion pair is composed of two lithium and a single sulfonated diphenyl sulfone ion whose properties are studied under the influence of different DMSO concentrations. For increasing mole fractions of DMSO, we observe a non-ideal beha...

Molecular Structure and Adsorption of Dimethyl Sulfoxide at the Surface of Aqueous Solutions

Surface vibrational sum frequency generation (VSFG) spectroscopy complemented with surface tension measurements has been utilized to probe the air/ dimethyl sulfoxide (DMSO) interface as a function of DMSO concentration in water. For the neat DMSO surface, the DMSO methyl groups extend away from the liquid phase and VSFG polarization studies show that the methyl transition dipole moments of pur...

DFT study of dimers of dimethyl sulfoxide in gas phase

Density functional (DFT) calculations at M05-2x/aug-cc-pVDZ level were used to analyze the interactions between dimethyl sulfoxide (DMSO) dimers. The structures obtained have been analyzed with the Atoms in Molecules (AIMs) and Natural Bond Orbital (NBO) methodologies. Four minima were located on the potential energy surface of the dimers. Three types of interactions are observed, CH•••O, CH•••...

Effect of ultrasound on ester hydrolysis in aqueous ethanol.

Kinetics of the acid-catalyzed hydrolysis of ethyl acetate in ethanol-water binary solutions were investigated without sonication and under ultrasound at 22 kHz. Rate enhancements by 1.03-2.4 times were found with a minimum at 18 wt.% and a maximum at 45 wt.% of ethanol. The results suggest that ultrasonic acceleration of the reaction may be interrelated to the perturbation of the molecular str...
