About this material
Dimethyl carbonate is the thinner of the two workhorse linear carbonates. Adding it to an EC-based blend drops viscosity, raises conductivity and pushes the freezing point down, which is why EC/DMC is the base of most standard formulations.
Its flash point of 17 °C makes it the most flammable component on the bench. It also hydrolyses slowly in the presence of base, so keep it dry and away from alkaline contamination — the methanol released shows up as a rising water number on the CoA.
Documentation, controls and care
Quality controls
- Certificate of analysis per batch
- Moisture by Karl Fischer, reported per lot
- Trace metal screening
- Retained samples held for 12 months
Handling & storage
- Flammable liquid with a 17 °C flash point — handle away from ignition sources and bond containers when dispensing.
- Keep sealed and dry; moisture ingress raises the water number and generates methanol.
- Store at 15–25 °C, away from strong bases and oxidisers.
