摘要: Provided are a water-soluble triarylphosphine for a palladium catalyst, which has high selectivity in a telomerization reaction and is easily recovered with efficiency, an ammonium salt thereof, and a method for efficiently producing the same. Specifically, provided are bis(6-methyl-3-sulphophenyl)(2-methylphenyl)phosphine; a bis(6-methyl-3-sulphonatophenyl)(2-methylphenyl)phosphine diammonium salt obtained by reacting the phosphine with a tertiary amine having a total of 3 to 27 carbon atoms in groups bonded to one nitrogen atom; and a method for producing the same.

摘要: An electric double layer capacitor has two polarized electrodes each comprising a porous sintered body, and two current collectors each made of an electrically conductive material composed of a base and electrically conductive fine particles mixed in the base. The current collectors are held in contact with surfaces of the polarized electrodes and enter pores of the polarized electrodes.

摘要: The polarizing electrode of an electrical double-layer capacitor cell is constituted with solid plate-like polarizing electrodes (61, 71) and paste-like polarizing electrodes (6, 7). The solid plate-like polarizing electrodes (61, 71) are counterposedly arranged by being separated with a separator (5). The paste-like polarizing electrodes (6, 7) are coated on the surfaces at the outside of the solid plate-like polarizing electrodes (61, 71). Since the paste-like polarizing electrodes (6, 7) contact also to the solid plate-like polarizing electrodes (61, 71) and the collecting electrodes (1, 2) well, the contact resistance becomes small.

摘要: In producing an electrical double-layer capacitor cell, when the polarizing electrode (61,71) is formed by sintering to the collecting electrode (11,21) obtained by sintering a conductive powder into plate-like form, the contact resistance between the collecting electrode (11,21) and the polarizing electrode (61,71) becomes extremely small. Thereby, the internal resistance of the electrical double-layer capacitor cell becomes small.
