标题 :Synthesis of fluorinated dimethyl ethers
发明人：O'NEILL GERALD J
权利人:GRACE W R & CO
摘要:A novel process is disclosed for the synthesis of fluorinated dimethyl ethers of the formula CF 2 HOCCl x F y H 3- (x+y) wherein x is 0, 1 or 2; y is 1, 2 or 3; and wherein the total x+y is 1, 2 or 3. The process involves chlorination of methyl difluoromethyl ether to form a chlorinated reaction product, including at least one compound of the formula CF 2 HOCH 3-z Cl z , wherein z is 1, 2 or 3, which compound is then fluorinated with HF and/or an antimony salt and with or without separation from the chlorinated reaction product, to give a fluorinated reaction product including the aforementioned fluorinated dimethyl ethers.

摘要:Methods of producing N,N-branched sulfamoyl fluoride compounds of the formula F-S(O) 2 -NR 2 by contacting bismuth trifluoride with an N,N-branched sulfamoyl nonfluorohalide compound of the formula X-SO 2 NR 2 , wherein X=chlorine (Cl), bromine (Br), or iodine (I), and each R is, independently, a linear or branched alkyl, fluoroalkyl, alkenyl, fluoroalkenyl, alkynyl, or fluoroalkynyl with 1 to 12 carbon atoms, to fluorinate the N,N-branched sulfamoyl nonfluorohalide compound. This is a non-aqueous method, the purity of product is very high, and the desired product can be isolated in quantitative yield. The N,N-branched sulfamoyl fluoride compounds so produced are useful in various applications including as electrolyte solvents and additives in electrochemical devices, such as lithium batteries and capacitors, and in biological fields, among others.
