Relaxation timeIntermolecular interactions.The density (ρ), refractive index (n_D), dielectric constant (ε_s) and relaxation time (τ) of binary mixture of allyl bromide with polar protic solvent n-butanol including those of the pure liquids, were measured over the complete composition range. ...
3. “Protic” Solvents Have O-H or N-H Bonds And Can Hydrogen-Bond With Themselves. “Aprotic” Solvents Cannot Be Hydrogen Bond Donors There’s a final distinction to be made and this also causes confusion. Some solvents are called “protic” and some are called “aprotic”. What makes ...
Such interpolymer complex formations were examined in several protic and aprotic solvents. The obvious relationship between the complex formation and the dielectric constant of the solvent was eludicated. The effect of hydrophobic interactions ...

Polar aprotic solvents, like tetrahydrofuran, are better solvents for this reaction than polar protic solvents because polar protic solvents will be solvated by the solvent hydrogen bonding to the nucleophile and thus hindering it from attacking the carbon with the leaving group. A polar aprotic ...

Influence of solvent-headgroup interactions on the formation of lyotropic liquid crystal phases of surfactants in water and nonaqueous protic and aprotic s... A fast method for the analysis of the phase diagrams of lyotropic compounds was employed to study the formation of liquid crystals from two...
Their main respective advantages are discussed with regard to the solvent and polymer chemical structures and the type of interactions involved in the sorption phenomenon.UNIQUAC-FV is shown to provide the best results for the sorption of aprotic species (ether, ester) in polyurethaneimides, as ...
Synthesis, Crystalline Complex Formation and X-Ray Crystal Structures of Three Inclusion Species have been prepared and shown to act as crystallinehosts for the inclusion of organic solvents involving protic polar, aprotic dipolar and apolar molecules. ...
