There are 3 types of solvents commonly encountered: nonpolar, polar aprotic, and polar protic.(There ain’t such a thing as a non-polar protic solvent). 4. Nonpolar Solvents Have Little To No Dipole Moment These solvents have low dielectric constants (<5) and are not good solvents for cha...
Liquid acetic acid is a hydrophilic (polar) protic solvent, similar to ethanol and water. With a moderate relative static permittivity (dielectric constant) of 6.2, it dissolves not only polar compounds such as inorganic salts and sugars, but also non-polar compounds such as oils as well as ...
Most biological processes take place in an aqueous environment. If we are to mimic Nature, the assembly of water-soluble supramolecular containers that can act as receptors in such polar and protic solvent constitutes a real challenge. The number of examples of molecular hydrogen-bonded capsules sel...
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. ...

Such secondary reactions can be minimized by reducing the pH since the protic acidity reverts the dissociation equilibrium of H2O2 into H+ and OOH−, so as to prevent the transformation of the generated OOH— into HOO, which in turn will take more H2O2 to H2O e O2 in spite of the co...
The present invention provides a method of manufacturing the same polycarbonate and has a response with respect to polar protic solvent. More specifically, for producing a polycarbonate as constituent units epoxide modified by a group formed from glycol units....
