Abstract: Methods and systems for an integrated acid regeneration of ion exchange resins are disclosed for use in cleaning applications. Acid resins designed for use in a variety of cleaning application using a treated, softened, acidic water source are disclosed. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins within a cleaning application, e.g. ware wash machine, are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.

Abstract: Multi-acid polymers for use as a fuel cell membrane, for example, have multi-acid monomers that have an imide base and more than two proton conducting groups. The multi-acid polymers are made by reacting a polymer precursor in sulfonyl fluoride or sulfonyl chloride form with a compound with an acid giving group. One example of a multi-acid polymer is: wherein R is one or more units of a non-SO2F or non-SO2Cl portion of a polymer precursor in sulfonyl fluoride or sulfonyl chloride form.

Abstract: An ion exchange chromatographic packing material is described that includes a copolymer grafted to support resin particles. The copolymer includes an ion exchange group, an ionic crosslinking group configured to ionically bind to the ion exchange group, and an adjustable ionization state group having at least a first net charge at the first pH and a second net charge at the second pH. An overall first net charge of the chromatographic packing material at the first pH is opposite in polarity to the overall second net charge of the chromatographic packing material. This allows impurities to be removed from the chromatographic packing material at the second pH.

Abstract: Method for preparing methyl formate and coproducing dimethyl ether by reacting a formaldehyde and methanol raw material (molar ratio range of 1:4 to 1:0.05) in a First Reaction Region at ranges from 50° C. to 100° C. with Catalyst A resulting in post-reaction material separated into Constituent I. Reacting Constituent I in a Second Reaction Region at ranges from 50° C. to 200° C. and from 0.1 MPa to 10 MPa with Catalyst B resulting in post-reaction material, which is separated into methyl formate, dimethyl ether and Constituent II. At least 1% of dimethyl ether is product, and recycling the rest to the First Reaction Region. Constituent II is recycled to the Second Reaction Region. Each component is gaseous phase and/or liquid phase, independently. The method shows long catalyst life, mild reaction condition, high utilization ratio of raw materials, continuous production and large scale industrial application potential.
