▎ 摘 要
NOVELTY - Purification method of vinylene carbonate involves removing the dimethyl carbonate solvent in the crude vinylene carbonate, obtaining the ethylene carbonate solution after removing the solvent, the ethylene carbonate solution after removing the solvent is added to the fractionating tower, then adding a certain amount of graphene modified active carbon into the fractionating tower decompressing and fractionating the vinylene carbonate solution after removing solvent in the fractionating tower, collecting fraction, obtaining the purified vinylene carbonate. USE - Purification method of vinylene carbonate. ADVANTAGE - The purification method of vinylene carbonate is highly efficient.
