    摘要： There are provided: a proton transporting material that improves mechanical characteristics of a sulfonated liquid crystalline polymer material, can be kept as a membrane even though it is made a solid state while maintaining a molecular arrangement of a liquid crystalline state, and is suitable for electrolyte membranes of fuel cells etc.; an ion exchange membrane, a membrane electrolyte assembly (MEA), and a fuel cell that use the proton transporting material; a starting material for the proton transporting material. The proton transporting material has a molecular structure produced by crosslinking the sulfonated liquid crystalline polymer material with a crosslinking agent having two or more functional groups in sites except that of the sulfonic acid group.

    摘要： Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's will extend the buffering range, derivatives that result in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability.

    摘要： Propanone-1,3-disulfonic acid (acetone disulfonic acid) may be prepared by reacting chlorosulfonic acid with acetone preferably in the presence of a solvent for the reactants, such as methylene chloride, although a neat reaction is possible. The reactants and reaction conditions prior to separation should be substantially anhydrous, but water may be added after reaction to separate the product as an aqueous solution.

    摘要： 2,4-pentanedione-1,5-disulfonic acid is prepared by reacting chlorosulfonic acid with 2,4-pentanedione with heating to a temperature greater than about 50.degree. C., preferably in the presence of an anhydrous solvent. The method of this invention generally yields 2,4-pentanedione-1,5-disulfonic acid in excess of about 60 percent. The novel pentanedionedisulfonic acid (2,4-pentanedione-1,5-disulfonic acid acetylacetone disulfonic acid) is disclosed.
