polar solvent
Molecular formula :
CAS :

nature : elements of positive charge and always negative charge or left to the center of positive and negative charge is not consistent solvent, with a high dielectric constant, was chemical activity, and formed Coordination covalent bond, such as alcohols and ketones. In chromatography analysis commonly used agents for the start of the solvent is water, Formamide, methanol, acetic acid, ethanol, isopropyl alcohol, acetone, 1:1, tert - butanol, phenol, n-butyl alcohol, amyl alcohol, ethyl acetate, ethyl ether, acid resin is small, chloroform, benzene, toluene and cyclohexane , petroleum ether. Ahead are hydrophilic polar solvent; Behind the non polarity or very weak polar solvents, they do not dissolve in water. At the end of the first middle-polar solvent. From water to tert - butanol, water miscible in any proportion.
