Are you looking for a chemical with low toxicity, low evaporation rate, and VOCs exemption? Propylene Carbonate has all of those characteristics and it is suitable for a variety of applications. Propylene carbonate also know as 1,2-propanediolcarbonate, 1,2-Propanediyl carbonate, 1,3-dioxolane-2-one,4-methyl, 1-Methylethylene carbonate, 2-Propanediolcycliccarbonate, short for PC. It is a VOC-exempt* clear polar solvent having high boiling and 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. It can be used for painting, coating, as a cleaning agent, and as solvent for many other industries.
Due to its low vapor pressure and findings of negligible photochemical reactivity, PC is currently considered VOC exempt by the US EPA. It is also considered a non-VOC according to EU dir 1999/13/EC. Because of its preferable safety and regulatory profile, PC has been a very effective substitute for traditionally used but more hazardous and heavily regulated solvents, including methylene chloride, perchloroethylene, NMP, acetone, MEK, and toluene.

Preparation of Propylene Carbonate (PC)
At present, the synthesis methods of propylene carbonate mainly include phosgene method, transesterification method, chloropropanol method and propylene oxide and CO2 synthesis method. The cycloaddition reaction of propylene oxide and CO2 to produce propylene carbonate has the advantages of high atomic utilization rate (100%), simple process and environmental friendliness, and has gradually become the main method for the production of propylene carbonate. The following are the general steps of the preparation method.
- Preparation of catalyst: Start by preparing a suitable catalyst, such as a quaternary ammonium salt or an organic base. The catalyst helps facilitate the reaction between propylene oxide and carbon dioxide.
- Reaction setup: In a reaction vessel, combine propylene oxide and carbon dioxide in the presence of the catalyst. The reaction typically takes place under elevated pressure and temperature.
- Reaction conditions: The reaction is typically carried out at temperatures ranging from 100 to 200 degrees Celsius and pressures ranging from 1 to 10 megapascals. These conditions promote the conversion of propylene oxide and carbon dioxide into propylene carbonate.
- Reaction progress: Allow the reaction to proceed for a specific period of time, usually a few hours, while maintaining the desired temperature and pressure. The reaction progress can be monitored by analyzing the reaction mixture at different time intervals.
- Product separation: Once the reaction is complete, separate the propylene carbonate from the reaction mixture. This can be done through various methods, such as distillation, extraction, or crystallization.
- Purification: Purify the obtained propylene carbonate to remove any impurities. This may involve additional distillation or filtration steps. After purification, you will have obtained propylene carbonate, which can be used for various applications.

Propylene Carbonate (PC) Applications
Lithium-ion batteries and Electronics
Propylene carbonate is an important cyclic carbonate solvent used in lithium-ion batteries (LIB) electrolytes. Its high dielectric constant of 64 makes it a valuable component in electrolytes for lithium batteries, often used in combination with low-viscosity solvents(e.g. dimethoxyethane). This combination helps enhance the performance and stability of the battery. In addition to its use in lithium batteries, propylene carbonate is also utilized as an effective circuit board and electronic cleaner. It is commonly used in the manufacturing of computers, cell phones, hybrid vehicles, and plug-in hybrid electric vehicles. Its solvent properties make it suitable for cleaning and degreasing electronic components.
Paint & Coatings
Propylene carbonate is used as a high-boiling solvent and film-forming auxiliary, especially in poly (vinyl fluoride) and poly (vinylidene fluoride) systems. It is also employed as an auxiliary in the pigment and dye industry. Propylene Carbonate is also more eco-efficient compared to other solvents used in wire enamel coating applications. As a reactive diluent, it can reduce the viscosity of isocyanates or polyurethane pre-polymers in two-component polyurea systems.
Cleaning, Stripping and Degreasing
Propylene carbonate has low toxicity and rapid biodegradability properties for solvents used in hard surface cleaning and degreasing formulations. Alone or combined with other solvents, it is effective as a polyurethane and polymer/resin cleaner, for cleaning up unsaturated polyester resins and gelcoats, as an all-purpose industrial and consumer cleaner, for cleaning stereolithographic parts, and as an ink cleaner.
Gas Treating and Petrochemical Applications
Propylene Carbonate is used as a physical solvent for removal of carbon dioxide (CO2) and hydrogen sulfide (H2S) in natural gas treating, oil pyrolysis gas, and synthetic ammonia conversion gas applications. It is also used as an oil solvent and as an extraction agent for olefins and aromatics. In Grignard reactions, it is used as an intermediate to create tertiary alcohols.
Other Uses and Applications
Propylene carbonate is used as a binder for foundry sand molds, as a plasticizer for polymers, and in pesticide formulations.
In the textile industry can be used as synthetic fiber additives and fixatives, spinning solvents, or water-solvent dye pigment dispersant.
Propylene Carbonate is not corrosive, therefore, it can be used in cosmetic and personal care products like make-up, antiperspirants, hair conditioners, and other products.
