Storage and Handling
Dimethyl Carbonate is a highly flammable liquid that can produce flammable vapor-air mixtures. Appropriate fire prevention measures, ventilation, and protective equipment are essential during storage and handling.
Use suitable chemical-resistant gloves, protective clothing, and safety goggles. Avoid inhaling vapors and prevent unnecessary skin or eye contact. Handle the material in adequately ventilated areas using equipment appropriate for flammable liquids.
Store in tightly closed, compatible containers in a cool, dry, well-ventilated area away from heat, sparks, open flames, and other ignition sources. Keep separate from incompatible materials, including strong oxidizing agents.
For moisture-sensitive applications, maintain the storage and handling conditions specified by the supplier to prevent contamination.
Always consult the current Safety Data Sheet (SDS) for exposure controls, firefighting precautions, spill response, transportation, and disposal requirements.
Quality and Supply
Dimethyl Carbonate may be supplied in industrial, high-purity, and specialized grades depending on the intended application and supplier availability.
Important purchasing considerations include product purity, moisture content, acidity, packaging compatibility, and application-specific quality requirements.
For lithium-ion battery electrolyte manufacturing, buyers should confirm that the supplied material meets the required battery-grade specifications.
The TDS, COA, and SDS should be reviewed before purchase to verify product quality, chemical compatibility, and safe handling requirements.
