Diethyl Carbonate

Diethyl carbonate (DEC) rounds out the battery carbonate solvent trio. Its higher boiling point and film-forming behavior contribute to stable electrode interfaces in lithium cells.

1. Electrolyte co-solvent for lithium-ion batteries (SEI film formation).
2. Ethylating and carbonylating reagent for fine-chemical synthesis.
3. Solvent for resins, cellulose derivatives and electrolytic applications.
4. Intermediate for pharmaceuticals and agrochemicals.

Supply and service. Diethyl carbonate from Dongying EastChem ships in 200 kg galvanized or blue steel drums — IBC on request. Nineteen years of chemical manufacturing across three subsidiaries keeps bulk supply stable year-round: minimum order one 20′ container, samples dispatched in about 2 days, T/T or L/C payment, and a batch-specific COA with every shipment. Combine with DMC, EMC and propylene carbonate in one mixed container. Contact our sales team for current specifications, pricing and delivery schedules.
