Propylene Carbonate (PC), CAS 108-32-7, is also known as 1,2-propylene carbonate or 4-methyl-1,3-dioxolan-2-one. It is used for industrial solvent, extraction and grade-specific electrolyte formulations. Before requesting a quotation, confirm assay, water content, acidity, colour, relevant impurities, packaging and intended formulation, and request current TDS, COA and SDS.

FAQ - Technical & Supply Chain
-
Q:
Are Propylene Carbonate and PC the same solvent?
A: Yes. Propylene carbonate and PC identify CAS 108-32-7, a cyclic carbonate solvent. They are not ethylene carbonate, dimethyl carbonate or propylene glycol. The purchase order should state industrial, battery or other grade, water limit and the intended use. -
Q:
What are the main industrial uses of Propylene Carbonate?
A: It is a polar aprotic solvent for coatings, cleaners, extraction and other process formulations. Electrolyte use requires a separately qualified grade with controlled water and impurities; the generic product identity does not establish battery grade. -
Q:
Which specifications matter when purchasing industrial Propylene Carbonate?
A: Agree assay by GC, water, colour, acidity, chloride or ionic impurities, nonvolatile residue and trace metals where relevant. Battery-electrolyte service typically requires tighter water and metal limits than general industrial solvent use, so the specification should match the application. -
Q:
What physical properties should be used to check an offered lot?
A: Confirm a clear, colourless liquid with melting point about -49 degrees C, boiling point about 240-243 degrees C, density about 1.204 g/cm3, refractive index about 1.419-1.422 and flash point about 132 degrees C. Normal grade variation can affect water, colour and acid content, so the specification should be agreed before release. -
Q:
What should be confirmed before bulk Propylene Carbonate delivery?
A: Confirm drum, IBC or tanker format, container compatibility, temperature range, quantity, previous cargo and unloading connection. Keep the material sealed and dry, follow the applicable flammable-liquid controls, and distinguish standard industrial PC from any separately qualified electrolyte grade.
