Problems solved by technology

[0008] While impregnated activated carbon tends to be more effective as an adsorbent for ammonia and volatile amines than activated carbon itself, the impregnated chemicals used can reduce the activated carbon's adsorption capacity for other volatile organic compounds (VOCs)

[0129] Gas adsorption analysis

[0130] Using the Rapid Surface Area and Porosity Analyzer (ASAP2020) system from Micromeritics Instrument Corporation (Norcross, GA), Micromeritics Instrument Corporation (Norcross, GA), USA, the porosity experiments and gas Adsorption experiment. Typical methods used to characterize porosity within example materials are described below. Take 50 to 300 mg of material into a half-inch diameter sample tube produced by Micromeritics, place the sample tube on the analytical port of ASPA 2020, and place the sample tube under ultra-high vacuum (3 to 7 μm Hg) at 150 °C for 2 hours to remove residual solvent and other adsorbates. When the relative pressure (p / p°) is less than 0.1, select low pressure dosing (low pressure dosing) mode (5cm 3 / g), and the argon adsorption isotherm at 77°K was obtained using a pressure plot of linearly spaced pressure points at relative pressures (p / p°) r...

[0139] Preparation Example 1 : Synthesis of 3,3,3',3'-tetramethyl-1,1'-spirobisindane-6,6'-divinyl (SBI-DV)

[0140] The monomer 3,3,3',3'-tetramethyl-1,1'-spirobisindane-6,6'-diethylene (SBI-DV) was prepared by first preparing 3,3,3',3' -tetramethyl-1,1'-spirobisindane-6,6'-diol (SBI-diol). The SBI-diol is then converted to perfluoromethane-1-sulfonic acid 6'-(perfluoromethane-1-sulfonyloxy)-3,3,3',3'-tetramethyl-1,1'- Spirobisindan-6-yl ester (SBI-bistriflate), which is further converted to SBI-DV.

[0142] 1000.69 g (4.38 moles) of 4,4'-isopropylidenediphenol (BPA) was melted in a 5.0 L round bottom flask. Once all the BPA had melted, 50.51 grams (0.526 moles) of methanesulfonic acid was slowly added. The temperature of the reaction mixture was maintained between 135°C and 150°C, and the reaction mixture was stirred under nitrogen atmosphere for 3 hours. After 3 hours, while still ...

Abstract

A method of capturing a basic, nitrogen-containing compound is provided. The basic, nitrogen-containing compound is captured by sorption (e.g., adsorption) on a sulfonic-acid containing polymeric material. The sulfonic acid-containing polymeric material is formed from a polymerizable composition that contains a free-radically polymerizable spirobisindane monomer. Additionally, a polymeric material is provided that is a reaction product of a sulfonic acid-containing polymeric material having at least one -SO3H group and a basic, nitrogen-containing compound of formula Q. This polymeric material has at least one group of formula -SO3 -(QH+).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 62 / 011694, filed June 13, 2014, the disclosure of which is incorporated by reference in its entirety. technical field [0003] The present invention provides a method of trapping basic nitrogen-containing compounds on sulfonic acid-containing polymer materials and materials resulting from the trapping. Background technique [0004] Ammonia is a commonly used chemical and is found in many different environments. For example, ammonia exists at various manufacturing sites for widespread range of chemical reactions. [0005] Ammonia vapors pose significant health risks. For example, in the United States, OSHA has set an 8-hour exposure limit of 25 ppm for ammonia vapor, and NIOSH has recently reduced IDLH (immediately threatening to life and health concentration) levels from 500 ppm to 300 ppm. That is, exposure to ammonia vapor at concentrations gr...
