  • Patent number: 9376373
    Abstract: The present invention provides novel polymerizable monomers having chelating functionality and processes to make them. In particular, the novel monomers are ethylenically unsaturated aminocarboxylates and are prepared by reacting ethylenediamine triacetic acid or its salt with an ethylenically unsaturated monomer. The ethyleneically unsaturated monomer may be a polymerizable vinyl monomer selected from (o-, p-, m-)DVBMO, allyl glycidyl ether, and glycidyl (meth)acrylate.
    Type: Grant
    Filed: August 6, 2015
    Date of Patent: June 28, 2016
    Inventors: Scott Backer, Allen Bulick, Joseph Manna, Cynthia Rand, Jia Xie
  • Patent number: 9346899
    Abstract: The present invention provides novel polymers having chelating functionality and comprising units derived from an ethylenically unsaturated aminocarboxylate monomer which comprises units derived from ethylenediamine triacetic acid or its salt and a polymerizable vinyl monomer. The polymerizable vinyl monomer may be selected from (0-, m-, p-)DVBMO, allyl glycidyl ether, and glycidyl (meth)acrylate. The polymer may also comprise units derived from one or more ethylenically unsaturated monomers.

  • Publication number: 20070166806
    Abstract: A process for making an amino acid by the steps of: (a) contacting a compound of formula I with a hydroformylation catalyst and synthesis gas to produce a mixture of aldehyde compounds comprising the formulas IIa, IIb and IIc; (b) reacting the mixture of aldehyde compounds from step (a) to produce a mixture of derivative compounds; (c) contacting the mixture of derivative compounds from step (b) with an enantioselective hydrolase enzyme in the presence of water to produce an L-amino acid having the formula IV; (d) isolating the amino acid having the formula IV in substantially pure form, wherein in formulas I, IIa, IIb, IIc, IIIa, IIIb, IIIc and IV, R is H, alkyl or aryl and R1 and R2 are the same or different alkyl groups and wherein R1 and R2 may be fused

  • Publication number: 20050070750
    Abstract: An olefin metathesis process involving contacting an unsaturated fatty acid ester or unsaturated fatty acid, such as methyloleate or oleic acid, with a lower olefin, preferably ethylene, in the presence of a metathesis catalyst so as to prepare a first product olefin, preferably, a reduced chain ?-olefin, such as methyl-9-decenoate or 9-decenoic acid, respectively. The metathesis catalyst contains ruthenium or osmium and a chelating ligand, preferably, a chelating ligand containing a carbene moiety and a second donor moiety of a Group 15 or 16 element Optionally, the catalyst can be supported on a catalyst support, such as, a cross-linked polymeric resin.
