  • Halogen Resistant Amides, Polyamides, and Membranes Made From the Same
    Publication number: 20160074817
    Abstract: A halogen resistant polyamide is formed from the reaction product of an amine monomer and an acid chloride monomer wherein the amino group of the starting amine monomer is separated from the aromatic amine ring system by an alkyl group and (i) minimizes halogenation on the amine and (ii) minimizes N-halogenation at a pH range of approximately 7 to approximately 10.5. A membrane is made from the polyamide for use, for example, in a reverse osmosis desalination unit.
    Type: Application
    Filed: September 17, 2015
    Publication date: March 17, 2016
    Inventors: Andrew P. Murphy, Robert L. Riley, Yuliana E. Porras Mendoza
  • CHLORINE RESISTANT AMIDES, POLYAMIDES, AND MEMBRANES MADE FROM THE SAME
    Publication number: 20140042082
    Abstract: A chlorine resistant polyamide is formed from the reaction product of an amine and an acid chloride monomer wherein both the amine and the acid chloride monomer are modified with electron-withdrawing groups that exhibit sufficient activity to (i) minimize any chlorination on both the amine and acid chloride and (ii) minimize N-chlorination. A membrane is made from the polyamide for use, for example, in a desalination unit.
