    摘要： To provide a novel immobilized product in which a carbon material and/or a silicon material is/are immobilized on a base material surface by a chemical bond via a linking group, and a method for producing the same. The immobilized product (10) of the present invention is an immobilized product in which a carbon material (11) is immobilizing on a surface of a base material (12), wherein the carbon material (11) is chemically bonded on the surface of the base material (12) via a linking group, and the linking group is at least any one selected from the group consisting of a -NH group, a -NH-R 1 -NH group, a -SO group, a R 2 group, an -O-R 3 -O group, and a R 4 group (in which the R 1 to R 4 each independently represent at least one selected from the group consisting of a chain alkyl group, a cyclic alkyl group, a chain alkenyl group, a cyclic alkenyl group, a chain alkynyl group, an aryl group, and functional groups in which at least one of a hydroxyl group, a halogen, an ester group, an ether group, a carbonyl group, an amino group, an amide group, a cyano group, a thiol group, a thioester group, or a thioether group is further bonded to these functional groups).

    摘要： Provided is a method for producing a difluorophosphate, which can simply and easily produce a high-purity difluorophosphate in an industrially advantageous manner. The method includes steps of: reacting an aqueous hydrofluoric acid solution with an oxyhalide of phosphorous (except phosphoric trifluoride) to produce a crude difluorophosphoric acid; reacting the crude difluorophosphoric acid with a halide of an alkali metal, an alkaline earth metal, aluminum or an onium to produce a difluorophosphate in the crude difluorophosphoric acid; and heating and drying the crude difluorophosphoric acid containing the difluorophosphate to distill away the crude difluorophosphoric acid, or precipitating the difluorophosphate in the crude difluorophosphoric acid by crystallization, subsequently separating the difluorophosphate by solid-liquid separation, and further distilling away the crude difluorophosphoric acid contained in the difluorophosphate after solid-liquid separation.

    摘要： An object of the invention is to provide a tetrafluoroborate producing method that allows high-yield, high-efficiency production of a tetrafluoroborate by a continuous process, a tetrafluoroborate-containing electrolyte, and an electrical storage device including such an electrolyte. The invention provides a method for producing a tetrafluoroborate, which includes: a first step including dissolving boron trifluoride gas in an organic solvent; a second step including adding, to the organic solvent, a fluoride (MF n , wherein M represents a metal or NH 4 , and 1 ≤ n ≤ 3) in an amount stoichiometrically equivalent to or less than the amount of the boron trifluoride so that a tetrafluoroborate solution is produced; and a third step including circulating the tetrafluoroborate solution through the first step so that the boron trifluoride gas is dissolved in the tetrafluoroborate solution instead of the organic solvent.
