For research and development scientists, a deep understanding of a chemical's properties is crucial for unlocking its full potential. Propylene Carbonate (PC), known by its CAS number 108-32-7, is a fascinating cyclic carbonate with a unique chemical structure that dictates its diverse reactivity and applications. As a specialized supplier of fine chemicals, we provide researchers with access to high-purity Propylene Carbonate to support their innovative work.

Propylene Carbonate is a five-membered ring structure featuring a carbonate ester group attached to a propylene backbone. Its molecular formula is C4H6O3, with a molecular weight of 102.09 g/mol. The presence of the polar carbonate group imparts significant polarity to the molecule, making it a highly effective polar aprotic solvent. This polarity arises from the uneven distribution of electron density within the molecule, particularly around the oxygen atoms of the carbonate group.

The chemical stability of Propylene Carbonate is a key feature. It is generally resistant to hydrolysis under neutral conditions, but it can undergo transesterification reactions with alcohols in the presence of catalysts, yielding dialkyl carbonates and propylene glycol. This reactivity is harnessed in certain synthetic pathways. For instance, it can react with amines to form carbamates, a process valuable in organic synthesis.

In terms of physical chemistry, Propylene Carbonate boasts a high dielectric constant (ε ≈ 64 at 25°C). This property is fundamental to its excellent performance as a solvent for electrolytes in electrochemical applications, such as lithium-ion batteries. The high dielectric constant allows it to effectively dissociate ionic salts, facilitating the movement of charge carriers. Researchers often explore PC in combination with various salts (e.g., LiPF6, LiTFSI) to optimize electrolyte properties for specific battery chemistries.

Its low freezing point (-49°C) and high boiling point (240°C) provide a broad operational temperature range, making it suitable for reactions and applications that require stability across a wide thermal spectrum. Additionally, its miscibility with many organic solvents, like ethanol, acetone, and ethyl acetate, allows for the creation of tailored solvent mixtures with specific polarity and solvency characteristics.

As a solvent, Propylene Carbonate is also recognized for its role in polymer science, acting as a solvent for certain polymers and as a monomer or co-solvent in polymerization processes. Its application in the synthesis of nanomaterials and its use as a medium for various catalytic reactions are areas of active research.
