Ethylene carbonate is an ester of ethylene glycol and carbonic acid. Ethylene carbonate is used as a polar solvent with a molecular dipole moment of 4.9 D, only 0.1 D lower than that of propylene carb onate. It can be used as a high permittivity component of electrolytes in lithium batteries.Purification Methods
Dry 1,3-dioxolan-2-one over P2O5, then fractionally distil it at low or atmospheric pressure. Recrystallise it from dry Et2O (plates, m 36.5o, 38.5-40o was also reported). It is soluble in H2O. [Beilstein 19 II 135,19 III/IV 1556, 19/4 V 6.]??? ????? ?? ?? ? ???
