Abstract
The present invention provides a process for preparing fluorinated 1,3-dioxolan-2-one by reacting a derivative of 1,3-dioxolan-2-one having halogen atom other than fluorine with an amine hydrofluoride in an organic solvent, and in this preparation process, fluorinated 1,3-dioxolane-2-on can be prepared in a short period of time by liquid-liquid reaction while maintaining high yield, by using a derivative of 1,3-dioxolan-2-one having halogen atom other than fluorine as a starting material and fluorinating the derivative with a fluorinating agent.
