摘要： It is an object of the present invention to provide an exhaust gas purifying catalyst filter which has enhanced soot collection performance without increasing pressure loss caused by the formation of a catalyst layer in a partition wall of a wall flow type substrate.
A gasoline engine exhaust gas purifying catalyst filter for purifying exhaust gas of a gasoline engine includes: a wall flow type substrate in which an introduction-side cell having an open exhaust gas introduction-side end, and a discharge-side cell adjacent to the introduction-side cell and having an open exhaust gas discharge-side end are defined by a porous partition wall; and a catalyst layer formed in a pore of the partition wall. An absolute value of a maldistribution degree of the catalyst layer formed in the pore of the partition wall is 4.50 or less. A wash coat amount, excluding a mass of a platinum group, of the catalyst layer formed in the pore of the partition wall, is 40 g/L or more and 50 g/L or less. The catalyst layer formed in the pore of the partition wall is a single layer. The catalyst layer is free of Ba.-

摘要： Provided is a hydrogenation catalyst for an amide compound, containing hydroxyapatite and platinum and vanadium that are fixed on the hydroxyapatite, 15 to 80% of the surface of the platinum being covered with vanadium. The hydrogenation catalyst can promote a reduction reaction in which an amide compound is converted into an amine compound, can be used under mild conditions, and has such durability that the catalyst can be repeatedly used while retaining a high activity.

摘要： An organometallic complex catalyst is disclosed for use in a cross-coupling reaction. In formula (1), M is the coordination center and represents a metal atom such as Pd or an ion thereof. R1, R2, and R3 may be the same or different and are a substituent such as a hydrogen atom. R4, R5, R6, and R7 may be the same or different and are a substituent such as a hydrogen atom. X represents a halogen atom. R8 represents a substituent that has a n bond and 3-20 carbon atoms. With regard to the electron-donating properties of R1-R7 with respect to the coordination center M of the ligand containing R1-R7 that is indicated in formula (2), R1-R7 are arranged in combination such that the TEP value obtained from infrared spectroscopy shifts toward the high frequency side compared to the TEP value of the ligand of formula (2-1).

摘要： Provided is a catalyst mixture which, in a nitro group hydrogenation reaction of an aromatic nitro compound having a structure in which nitro groups and halogen atoms are directly bonded as substituents to a ring skeleton of the same ring while separated from each other, is capable of selectively hydrogenating the nitro groups and sufficiently reducing the removal of the halogen atoms from the ring. This catalyst mixture includes a catalyst which is used in a hydrogenation reaction of at least one among one or more nitro groups present in a reactant, which is an aromatic nitro compound having a structure in which one or more nitro groups and one or more halogen atoms are directly bonded as substituents to a ring skeleton of the same ring while separated from each other.

摘要： The present invention provides a technique capable of adjusting the loading positions of gold and palladium in a VAM catalyst by a method of producing a palladium-gold loaded catalyst for vinyl acetate synthesis. The method includes a step of impregnating a spherical porous molded carrier of an inorganic oxide with a mixed aqueous solution containing a palladium precursor as a catalytically active species and a gold precursor as a co-catalyst component, and subsequently impregnating the resultant spherical porous molded carrier with an aqueous alkaline solution to water-insolubilize the palladium precursor and the gold precursor in the spherical porous molded carrier to obtain a palladium-gold immobilized spherical porous molded carrier; and a subsequent step of adjusting the moisture content of the palladium-gold immobilized spherical porous molded carrier.
