Abstract: The present invention relates to a method for producing fluorine-containing dialkyl carbonate compounds, which are suitable as non-aqueous solvents for non-aqueous electrolytes used in secondary batteries. When an alkyl chloroformate and an alcohol are reacted in the presence of an ether-containing imidazole derivative base, the reaction can be carried out at room temperature as compared with the prior art, and the products can be separated within a short time from the reactants. This is an economical process, and according to the present invention, it is possible to obtain alkyl carbonates containing fluorine atoms simply and without difficulty in the removal of solvents, salts formed during the reaction, and by-products.

Abstract: The present invention relates to a method for preparing a fluorinated methacrylate compound which can be used as a fluorine monomer for synthesizing a functional polymer having high oxygen permeability, water repellency and stain resistance. Specifically, the method can be carried out by a process of reacting an alcohol derivative and methacrylic acid anhydride in the presence of an imidazole-based base to obtain a fluorinated methacrylate. According to the preparation method of the present invention, since the reaction is carried out at room temperature and there is no process of removing the byproducts formed during the reaction, a high yield of fluorinated methacrylate can be obtained by a simple method within a short period of time.
