Abstract

A process for preparing 4-fluoro-1,3-dioxolan-2-one comprising adding 4-fluoro-1,3-dioxolan-2-one to ethylene carbonate in an amount of from 3 to 20% by weight relative to the ethylene carbonate as a solvent for the ethylene carbonate, and introducing fluorine or a mixture containing fluorine in an inert gas is introduced into the resulting solution at 15 to 45° C.
