Propylene carbonate (PC) is a polar aprotic substance with very similar physicochemical characteristics to the organic solvents traditionally used for organic synthesis, such as acetonitrile and acetone.
Therefore, PC is beginning to be used as a “green” sustainable alternative solvent for chemical transformations. PC is a low toxicity, non-corrosive colourless liquid with a high boiling point and low vapour pressure.
It is biodegradable and economical, allowing its large-scale use. PC can be prepared by a reaction between propylene epoxide and carbon dioxide with 100% atomic economy. The easy preparation of propylene epoxide and the use of an available, abundant, economical, and renewable source of carbon, such as CO2, make this process one of the best routes for the synthesis of PC.
Therefore, we present in this review numerous catalytic systems that have been studied to improve the efficiency of this reaction. Certain interesting examples of reactions using PC are found in the literature, of which we discuss asymmetric hydrogenation, hydrosilylation, asymmetric aldol reactions, the asymmetric synthesis of cyanohydrins, the synthesis of heterocyclic compounds, such as bisindole and tetrahydroquinoline, the hydroacylation of alkynes, α-hydrazination reactions, oxidations, the Sonogashira reaction, allylic alkylation and asymmetric amination, the Heck reaction, enzymatic kinetic resolution, and isomerisation-hydroformylation reactions.
Keywords: Propylene carbonate, carbonic acid diesters, green chemistry, green solvent, organic synthesis, environment.
Use: Propylene Carbonate (PC) is a VOC-free clear polar solvent having high boiling and flash points. Propylene Carbonate (PC) is a carbonate ester derived from propylene glycol with the peculiarity to have a low order of toxicity and a mild ether-like odor. Propylene Carbonate (PC) is stable under most conditions and it is not hydroscopic or corrosive. It is particularly well suited for applications requiring a water white product or high purity. It can be used in cosmetics and personal care products; mainly in the formulation of make-up, primarily lipstick, eye shadow, and mascara, as well as in skin cleansing products.
Use: Propylene carbonate is used in a variety of syntheses and applications as a polar, aprotic solvent. It can also be found in some adhesives, paint strippers, cosmetics, and can be used as a plasticizer.
Description
General description
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.
It is being considered as a potential electrochemical solvent due to its low vapor pressure, high dielectric constant and high chemical stability.
Application
Propylene carbonate may be used as a solvent for the asymmetric hydrogenation of nonfunctionalized olefins.
Propylene carbonate (often abbreviated PC) is an organic compound with the formula C4H6O3. It is a cyclic carbonate ester derived from propylene glycol.
This colorless and odorless liquid is useful as a polar, aprotic solvent.
Propylene carbonate is chiral, but is used exclusively as the racemic mixture in most contexts.
Preparation
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
As a solvent
Propylene carbonate is used as a polar, aprotic solvent. 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).
It is possible, for example, to obtain potassium, sodium, and other alkali metals by electrolysis of their chlorides and other salts dissolved in propylene carbonate.
Due to its high 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, it 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. It 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 (see Carbonate ester#Carbonate transesterification).
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.

Methods of Manufacturing
The most important and versatile method for producing carbonates is the phosgenation of hydroxy compounds.
Over the past 20 years, the trend is to manufacture carbonates without the use of phosgene.
This method has the advantage of avoiding the use of highly toxic phosgene as well as considerably lower cost.
The catalytic insertion of CO2 with oxiranes directly provides the five-membered cyclic carbonate.
Oxiranes such as ethylene oxide and propylene oxide undergo insertion at ~150-175 °C under pressure with the aid of a quaternary ammonium salt catalyst to yield ethylene carbonate and propylene carbonate, respectively.
Propylene carbonate dipolar aprotic solvent is a next-generation, high performing solvent.
Propylene carbonate works well in a variety of different applications thanks to its excellent solvency power and water miscibility. It is a safer alternative to commonly used dipolar aprotic solvents like NMP (N-methylpyrrolidone), DMAc (dimethylacetamide), DMSO (dimethylsulfoxide), DMF (dimethylformamide), and acetonitrile, some of which face increasing regulatory pressure.

Propylene Carbonte is a high performance, safer cosolvent for water-based polyurethanes. Effective as both a solvent and coalescent for the PUD market
Cleaners and paint strippers
When employed in cleaners and paint strippers, Propylene Carbonate has demonstrated to be an effective NMP replacement.
The high solvency power can enhance performance of industrial cleaning formulations. Propylene Carbonate can be used for cleaning molds or tools related to polyurethane foam, polymer, polyester, or epoxy resins.
The lower volatility of Propylene Carbonate is beneficial for reduced worker and environmental exposure.
Pharmaceutical synthesis
Propylene carbonate can be considered for use as a medium to carry out various chemical reactions, such as the production of pharmaceuticals. In such applications, it can be a replacement for solvents like NMP, NEP, DMF, and DMAc.
Safety
Clinical studies indicate that propylene carbonate does not cause skin irritation or sensitization when used in cosmetic preparations, whereas moderate skin irritation is observed when used undiluted.
No significant toxic effects were observed in rats fed propylene carbonate, exposed to the vapor, or exposed to the undiluted liquid.
In the US, propylene carbonate is not regulated as a volatile organic compound (VOC) because it does not contribute significantly to the formation of smog and because its vapor is not known or suspected to cause cancer or other toxic effects.

flash points, a low order of toxicity and a mild ether-like odor. It is stable under most
conditions and is not hydroscopic or corrosive. is particularly well suited for applications
requiring a water white product or high purity. Examples would be cosmetics, electronics
or where recycling of spent material will occur.
