标 题:Process for the synthesis of ethers of aromatic acids
发明人:RITTER JOACHIM C
权利人:DU PONT
摘要:The inventions disclosed herein include processes for the preparation of an ether of an aromatic acid, processes for the preparation of products into which such an ether can be converted, the use of such processes, and the products obtained and obtainable by such processes. A key feature of the processes described is the use of a solvent comprising an alcohol ROH and an alcoholate RO − M + .

摘要:Fluorinated ethers of aromatic acids are produced from halogenated aromatic acids in a reaction mixture containing a copper (I) or copper (II) source and a Schiff base ligand that coordinates to copper. The fluorinated ethers of aromatic acids made using the process described herein can be applied to, e.g., fibers, yarns, carpets, garments, films, molded parts, paper and cardboard, stone, and tile to impart soil, water and oil resistance. By incorporating the fluorinated ethers of aromatic acids, or diesters thereof, into polymer backbones, more lasting soil, water and oil resistance, as well as improved flame retardance, can be achieved.
