FLUOROCARBON ETHERS HAVING SUBSTITUTED HALOGEN SITE(S) AND PROCESS TO PREPARE

摘要

Novel perhalofluoro ethers and methods for preparing the same having generic formula, wherein, a is 0 or an integer greater than 0; b is 0 or an integer greater than 0; m = zero or an integer greater than zero; n = zero or an integer greater than zero; Rf and Rf are each independently selected from the group consisting of F, C1, perfluoroalkyl and fluorochloroalkyl; X = F, C1, Br, or mixtures thereof when n >1; X' is independently C1 or Br, or mixtures thereof; Y is an acid group or an acid derivative easily convertible to an acid group; Z = F, C1, Br, OH, NRR' or OA; R and R' are independently selected from the group consisting of hydrogen, an alkyl having one or more than one carbon atom and aryl; A = alkali metal, quaternary nitrogen, or R. These compounds may be reacted to form various derivatives.
