High Purity Ethylene carbonate (C3H4O3), 99.99%, 4N

Ethylene carbonate (EC) is utilized as a polar solvent and a high-permittivity component for lithium batteries electrolyte solutions, as well as for surface coatings, dyes, fibers, and plastics. It plays a role in the synthesis of aliphatic polyurethanes, ring-opening polymerization, transesterification reactions, producing dimethyl carbonate and glycerol carbonate, and as a plasticizer and precursor to vinylene carbonate. Further, it is used as a release agent and detergent, as it dissolves large amounts of electrolyte and polymers.
