Highly Swellable Composite Polyamide Membrane

US Patent:
2016031, Nov 3, 2016
Filed:
Dec 15, 2014
Appl. No.:
15/104023
Inventors:
- Midland MI, US
Nicholas S. Beck - Minneapolis MN, US
Robert C. Cieslinski - Midland MI, US
Bruce B. Gerhart - Midland MI, US
David D. Hawn - Midland MI, US
Duane Jacobson - Minneapolis MN, US
Mou Paul - Edina MN, US
Carl W. Reinhardt - Kawkawlin MI, US
Katmerka Tabakovic - Edina MN, US
Ian A. Tomlinson - Midland MI, US
International Classification:
B01D 69/12
B01D 67/00
B01D 71/56
Abstract:
A method for making a composite polyamide membrane including the step of applying a polar solution including a polyfunctional amine monomer and a non-polar solution comprising a polyfunctional acyl halide monomer to a surface of a porous support and interfacially polymerizing the monomers to form a thin film polyamide layer, wherein the method is characterized by including a tri-hydrocarbyl phosphate within the polar coating solution. The thin film polyamide layer is characterized by possessing an equilibrium water swelling factor of greater than 35% as measured by PFT-AFM.

Composite Polyamide Membrane With Improved Structure

US Patent:
2015016, Jun 18, 2015
Filed:
Jul 3, 2013
Appl. No.:
14/407366
Inventors:
Abhishek Roy - Edina MN, US
Tina L. Arrowood - Elko New Market MN, US
Anand S. Badami - Midland MI, US
Robert C. Cieslinski - Midland MI, US
David D. Hawn - Midland MI, US
Steven D. Jons - Eden Prairie MN, US
Mou Paul - Edina MN, US
Steven Rosenberg - Shorewood MN, US
Huang Wu - Midland MI, US
International Classification:
B01D 71/56
B01D 69/12
B01D 69/10
B01D 67/00
Abstract:
A thin film composite polyamide membrane having a porous support and a thin film polyamide layer comprising a reaction product of m-phenylene diamine (mPD) and trimesoyl chloride (TMC), characterized by the thin film polyamide layer having a critical strain value of less than 10%. In another embodiment, the thin film polyamide layer has a modulus of greater than 0.75 (GPa). In yet another embodiment, the thin film polyamide layer has an equilibrium swelling value of at least 45%. In another embodiment, the thin film polyamide layer has a thickness of at least 230 nm.

Cheng Li Zu - Midland MI, US
International Classification:
B01D 71/56
B01D 69/12
Abstract:
A thin film composite polyamide membrane including a porous support and a thin film polyamide layer which is a reaction product of m-phenylene diamine (mPD) and trimesoyl chloride (TMC), wherein the membrane is characterized by the thin film polyamide layer having a dissociated carboxylic acid content of at least 0.18 moles/kg at pH 9.5, and wherein pyrolysis of the thin film polyamide layer at 650 C results in a ratio of responses from a flame ionization detector for fragments produced at 212 m/z and 237 m/z of less than 2.8.

2015015, Jun 4, 2015
Filed:
Jul 3, 2013
Appl. No.:
14/405711
Inventors:
- Midland MI, US
Tina L. Arrowood - Elko New Market MN, US

Assignee:
Dow Global Technologies LLC - Midland MI
International Classification:
B01D 69/12
Abstract:
A method for making a composite polyamide membrane comprising a porous support and a thin film polyamide layer, wherein the method includes the step of applying a polyfunctional amine monomer and polyfunctional acyl halide monomer to a surface of the porous support and interfacially polymerizing the monomers to form a thin film polyamide layer, wherein the step of applying the polyfunctional acyl halide monomer to the porous support includes the step of combining the polyfunctional acyl halide monomer with a non-polar solvent at a concentration of at least 0.18 weight percent to form a coating solution which is applied to the surface of the porous support, and wherein the interfacial polymerization is conducted in the presence of a tri-hydrocarbyl phosphate compound which is provided in a molar ratio of at least 0.5:1 with the polyfunctional acyl halide monomer. Many additional embodiments are described including membranes made from the subject method and applications for such membranes.
