| | Vinylene carbonate Usage And Synthesis |
| Chemical Properties | clear colorless to light yellow liquid | | Uses | Vinylene carbonate is used as an additive to electrolyte solutions for anode side Lithiumion batteries. It also acts as a sealant to seal at least a portion of the silicon-polyvinyl acid interface. It is further used for great improvement of high temperature performance of the battery. | | Application | Vinylene carbonate (VC) can be used as an electrolytic additive for ionic liquid electrolyte for the formation of lithium-ion batteries. It can also be used in the formation of hybrid solid electrolyte interphase (SEI) for the fabrication of lithium-based batteries. | | Preparation | Vinylene carbonate is produced by the known method by eliminating hydrogen chloride from chloroethylene glycol carbonate by means of tertiary amines, in particular triethylamine. Chloroethylene glycol carbonate is obtained by free radical chlorination of ethylene glycol carbonate by means of chlorine or sulphuryl chloride. This synthesis was published for the first time in 1953 by Newman and Addor (JACS, 1953, page 1263; JACS 1955, page 3789). | | General Description | This product has been enhanced for energy efficiency. Carbonate building block offered as a solution in ethyl acetate for more convenient handling. Vinylene carbonate may also be used as a dienophile in Diels-Alder reactions. | | Flammability and Explosibility | Nonflammable | | Purification Methods | Purify it by zone melting, or distillation, and stabilize it with 0.5% of 2,6-di-tert-butyl-p-cresol.
