  2. Polar aprotic solvent - Wikipedia

    en.wikipedia.org/wiki/Polar_aprotic_solvent

    A polar aprotic solvent is a solvent that lacks an acidic proton and is polar. Such solvents lack hydroxyl and amine groups. In contrast to protic solvents, these solvents do not serve as proton donors in hydrogen bonding, although they can be proton acceptors. Many solvents, including chlorocarbons and hydrocarbons, are classifiable as aprotic ...

  3. Dimethyl sulfoxide - Wikipedia

    en.wikipedia.org/wiki/Dimethyl_sulfoxide

    Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O.This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.

    In chemical reactions the use of polar protic solvents favors the S N 1 reaction mechanism, while polar aprotic solvents favor the S N 2 reaction mechanism. These polar solvents are capable of forming hydrogen bonds with water to dissolve in water whereas non-polar solvents are not capable of strong hydrogen bonds.

  5. Tetraethylene glycol dimethyl ether - Wikipedia

    en.wikipedia.org/wiki/Tetraethylene_glycol_di...

    Tetraethylene glycol dimethyl ether (TEGDME or tetraglyme) is a polar aprotic solvent with excellent chemical and thermal stability.Its high boiling point and stability makes it an ideal candidate for separation processes and high temperature reactions.

  6. Propylene carbonate - Wikipedia

    en.wikipedia.org/wiki/Propylene_carbonate

    Propylene carbonate is used as a polar, aprotic solvent. [7] It has a high molecular dipole moment (4.9 D), considerably higher than those of acetone (2.91 D) and ethyl acetate (1.78 D). [1] It is possible, for example, to obtain potassium, sodium, and other alkali metals by electrolysis of their chlorides and other salts dissolved in propylene ...

  7. Solvent effects - Wikipedia

    en.wikipedia.org/wiki/Solvent_effects

    Note the decrease in ΔG ‡ activation for the polar-solvent reaction conditions. This arises from the fact that polar solvents stabilize the formation of the carbocation intermediate to a greater extent than the non-polar-solvent conditions. This is apparent in the ΔE a, ΔΔG ‡ activation. On the right is an S N 2 reaction coordinate diagram.

  9. Inorganic nonaqueous solvent - Wikipedia

    en.wikipedia.org/wiki/Inorganic_nonaqueous_solvent

    An inorganic nonaqueous solvent is a solvent other than water, that is not an organic compound. These solvents are used in chemical research and industry for reactions that cannot occur in aqueous solutions or require a special environment. Inorganic nonaqueous solvents can be classified into two groups, protic solvents and aprotic solvents.
