摘要:A composition includes an aqueous solution including at least one fluorinated organic compound; and a reaction product of a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. A method of making a catalyst includes reacting a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. The water may include less than or equal to 1 weight percent dissolved molecular oxygen. The catalyst may be used for degrading fluorinated organic chemicals in aqueous media.

标题:5-(hydroxymethyl) furan-2-carbaldehyde (hmf) sulfonates and process for synthesis thereof
发明人：STENSRUD KENNETH
权利人:ARCHER DANIELS MIDLAND CO
摘要:5-(hydroxymethyl)furan-2-carbaldehyde (HMF)-sulfonates and a method of preparing the same are described. The method involves reacting a mixture of 5-(hydroxymethyl)furfural (HMF), with at least one of a) a trifluoromethanesulfonate anhydride (triflate), b) a p-toluene-sulfonyl halide (tosylate), and c) methane-sulfonyl halide (mesylate), and a reagent of either 1) a nucleophilic base or 2) a combination of a non-nucleophilic base and a nucleophile. The HMF-sulfonates (e.g., triflate, tosylate, mesylate, etc. analogs of HMF) can serve as precursor materials from which various derivative compounds can be synthesized.
