Butylene carbonate

Butylene carbonate (CAS 4437-85-8), also known as 1,2-butylene carbonate, is a high-boiling cyclic carbonate solvent.

Where is Butylene carbonate used?

• Lithium-ion battery electrolytes: co-solvent improving low-temperature performance and ionic conductivity
• Polymer and resin systems: reactive diluent compatible with polycarbonate or polyurethane
• Industrial and institutional cleaning: slow-evaporating carrier solvent
• Lubricant and metalworking fluids: additive solvation and base fluid
• It serves as a practical alternative to conventional solvents where reduced evaporation losses matter.

Good to know: High-purity grades are used for battery electrolyte and electronics applications where moisture and impurity thresholds are tightly controlled.

Commercial specifications

• High-purity grades available for battery electrolyte and electronics
• Clear liquid in drum and IBC quantities, with bulk availability
