Propylene carbonate is chiral, but is used as the racemic mixture in most contexts.

Preparation of Propylene carbonate
Although many organic carbonates are produced using phosgene, propylene and ethylene carbonates are exceptions. 
They are mainly prepared by the carbonation of the epoxides (epoxypropane, or propylene oxide here):

CH3CHCH2O + CO2 → CH3C2H3O2CO

The process is particularly attractive since the production of these epoxides consumes carbon dioxide. 
Thus this reaction is a good example of a green process. 
The corresponding reaction of 1,2-propanediol with phosgene is complex, yielding not only propylene carbonate but also oligomeric products.
Propylene carbonate can also be synthesized from urea and propylene glycol over zinc acetate.

Applications of PROPYLENE CARBONATE

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

Electrolyte 
Due to its high relative permittivity (dielectric constant) of 64, it is frequently used as a high-permittivity component of electrolytes in lithium batteries, usually together with a low-viscosity solvent (e.g. dimethoxyethane). 
Its high polarity allows it to create an effective solvation shell around lithium ions, thereby creating a conductive electrolyte. 
However, Propylene carbonate is not used in lithium-ion batteries due to its destructive effect on graphite.

Propylene carbonate can also be found in some adhesives, paint strippers, and in cosmetics.
Propylene carbonate is also used as plasticizer. 
Propylene carbonate is also used as a solvent for removal of CO2 from natural gas and synthesis gas where H2S is not also present. 
This use was developed by El Paso Natural Gas Company and Fluor Corporation in the 1950s for use at the Terrell County Gas Plant in West Texas, now owned by Occidental Petroleum.

Other
Propylene carbonate product may be converted to other carbonate esters by transesterification as well.
In electrospray ionization mass spectrometry, propylene carbonate is doped into low surface tension solutions to increase analyte charging.
In Grignard reaction propylene carbonate (or most other carbonate esters) might be used to create tertiary alcohols.

Use and Manufacturing of Propylene carbonate
Used for carbon dioxide recovery and solvent extraction; Also used in lithium batteries, as a plasticizer, in natural gas purification, and as a synthetic fiber spinning solvent; Used as a solvent in surface coatings, paint removers, cosmetics, personal care products, cleaners, degreasers, dyes, fibers, plastics, wood-binder resins, and photochromic solutions; Also used as a solvent to bake enamels, a reactive diluent for urethanes and epoxy resins, a dispersant for lubricants and greases, a binder for foundry sand and moulds, a cleaner in electronics, and as a water scavenger

Propylene carbonate can be synthesized from propylene oxide and CO2.
Optically active form of propylene carbonate can be prepared from the reaction between CO2 and racemic epoxides.
Decomposition of propylene carbonate on the graphite electrode in lithium batteries results in the formation of a lithium intercalated compound.
Propylene carbonate is a cyclic carbonate that is commonly used as a solvent and as a reactive intermediate in organic synthesis.
Propylene carbonate is being considered as a potential electrochemical solvent due to its low vapor pressure, high dielectric constant and high chemical stability.

Propylene carbonate is a polar aprotic solvent used as a “green” sustainable alternative solvent for chemical transformations. 
Propylene carbonate is a low toxicity, biodegradable, non-corrosive colorless liquid with a high boiling point, low vapor pressure, and EPA VOC exemption.
Due to its low vapor pressure and findings of negligible photochemical reactivity, Propylene Carbonate is an effective substitute for more hazardous solvents such a MEK, methylene chloride, toluene, acetone, NMP, and perchloroethylene. 
Propylene carbonate is also compatible with other solvents providing an efficient ingredient in co-solvent formulations. 
Propylene carbonate is widely used in the manufacture of paints, adhesives, coatings, surface cleaners, degreasers, strippers, and inks formulations as well as in lithium-ion batteries, as electrolytic solvent, and in the removal of carbon dioxide from natural gas.

Propylene carbonate is a polymer that belongs to the class of polycarbonates. 
Propylene carbonate is synthesized by the reaction of propylene carbonate with chlorine atoms. 
The morphology, or shape, of this polymer can be changed by changing the amount of chlorine atoms used in the synthesis. 
Propylene carbonate has a high degree of crystallinity and these crystals are composed mainly of hydrogen bonds. 
This polymer also has a high degree of viscosity and melting point, which decreases with increasing chlorine atom content. 
Propylene carbonate has a low solubility in water and does not dissolve in common organic solvents.

Chemical Properties of Propylene carbonate
Propylene carbonate is soluble in water and miscible with most organic solvents. 
Propylene carbonate is found to be an excellent low-boiling solvent for cellulose acetate, nitrocellulose, adhesive compositions and vinyl chloride-acetate resins. 
Propylene carbonate is also a solvent for hydrocarbons, gums and shellac. 
Some of its uses are as a solvent and stabilizer in DDT aerosol-type insecticides, and as a fumigant and food preservative. 
Since it is an acid acceptor, Propylene carbonate is also used as a stabilizer for vinyl chloride resins and other chlorinated systems.
