Propylene carbonate as a solvent applications


Propylene carbonate is used as a polar, aprotic solvent.It has a top atomic dipole moment (4.9 D), appreciably college than those of acetone (2.91 D) and ethyl acetate (1.78 D).It is possible, for example, to access potassium, sodium, and added acrid metals by electrolysis of their chlorides and added salts attenuated in propylene carbonate.
Due to its top dielectric connected of 64, it is frequently used as a high-permittivity basic of electrolytes in lithium batteries, usually calm with a low-viscosity solvent. Its top polarity allows it to actualize an able solvation carapace about lithium ions, thereby creating a conductive electrolyte. However, it is not used in lithium-ion batteries due to its annihilative aftereffect on graphite.

Propylene carbonate can aswell be begin in some adhesives, acrylic strippers, and in cosmetics. It is aswell used as plasticizer. Propylene carbonate is aswell used as a bread-and-butter for abatement of CO2 from accustomed gas and amalgam gas area H2S is not aswell present. This use was developed by El Paso Accustomed Gas Company and Fluor Corporation in the 1950s.
