DMC refining Technology

 – From CO₂ and Propylene Oxide to High-Purity Product

Our dimethyl carbonate (DMC) refining technology starts from sustainable raw materials: carbon dioxide and propylene oxide. Through an integrated process route, we first produce propylene carbonate, followed by transesterification to generate DMC and co-product propylene glycol. This approach not only valorizes CO₂ emissions but also offers an economically attractive pathway to a versatile green solvent and chemical intermediate.

What distinguishes our DMC refining process is the combination of high-efficiency separation and purification steps tailored to achieve battery-grade and industrial-grade DMC. Our technology features low-energy distillation sequences, advanced extractive distillation, and optimized column internals to break azeotropes and remove trace methanol and water. The result is DMC purity exceeding 99.9% with minimal byproduct formation.

We offer flexible process configurations to meet different capacity and purity requirements. Our refining system delivers stable operation, high recovery yields, and low utility consumption. Whether your application is lithium-ion battery electrolytes, polycarbonate synthesis, or specialty chemicals, our DMC refining technology provides a reliable, cost-effective solution that turns CO₂ into value.
