    摘要: A process for preparing articles having a fluorocarbonsulfonic ionomer layer, such as membranes and catalysts, is disclosed wherein the fluorocarbonsulfonic ionomer is deposited upon support using an new annealing process. The annealing process of the present invention includes the step of heating a fluorocarbonsulfonic ionomer coated substrate in the presence of a vaporous solvent. This process provides for fluorocarbonsulfonic ionomer coated articles which can be annealed quickly at temperatures below the degradation point of many desirable support materials.

    摘要: A process for the recovery of an acid in its anhydrous form from an aqueous solution containing the acid in its hydrated form. Adding to the solution a weak base in the form of a soluble salt of the acid and concentrating the solution containing the acid hydrate and the salt of the acid to a substantially water-free, acid-salt mixture. The acid is distilled off in its anhydrous form from the acid salt mixture.

    摘要: Disclosed is a process for removing acid soluble oils, produced as an undesirable by-product of an acid catalyzed alkylation reaction, from a mixture containing a strong acid and methanesulfonic acid. The process includes the use of water to induce the formation of the two immiscible liquid phases of ASO and methanesulfonic acid with water. The two immiscible phases can subsequently be separated from each other.

    摘要: A method of regenerating a deactivated fluorocarbonsulfonic acid polymer catalyst by contacting the deactivated catalyst with a solvent combination wherein a first solvent swells the structure of the polymer and the other acts as a diluent to modify the swelling action of the first. The combination dissolves the deactivating components.
