Abstract: An object is to provide a method for producing a catalyst molded article which is high in mechanical strength and which enables unsaturated aldehyde and/or unsaturated carboxylic acid to be produced at high yield(s). The object is achieved by a method for producing a catalyst molded article, the method including (1) a step of adding an ammonium radical to a slurry (liquid A) including molybdenum and phosphorus, at a rate satisfying the following expression (I), to prepare a slurry (liquid B), 0.1?v/M?3 (I), in which v represents the rate of addition of the ammonium radical [mol/hour], and M represents the mass of the liquid A [kg], (2) a step of adjusting the pH of the liquid B, to prepare a slurry (liquid C) having a pH lower than that of the liquid B by 0.

Abstract: Audio equipment configured to perform a special operation or an effecting on music data being played by an external device includes: an operation control signal group storage configured to store an operation control signal group for commanding the special operation or the effecting for the music data; an operation control signal group calling section configured to call up the operation control signal group stored in the operation control signal group storage at a timing in accordance with an operation by an operator; and an operation control signal group outputting section configured to output the operation control signal group called by the operation control signal group calling section to the external device.

Abstract: Provided is a method for producing at least one type of thermoplastic resin selected from polycarbonate, polyester and polyester carbonate. The method includes a step of subjecting a dihydroxy compound and diaryl carbonate and/or dicarboxylic acid ester to melt polycondensation in the presence of a transesterification catalyst selected from a compound represented by formula (1) and/or formula (2). In formula (1), R1 to R24 are each a hydrogen atom, an alkyl group having 1-10 carbon atoms or a cycloalkyl group. Some of the carbon atoms may be substituted by heteroatoms. Among R1 to R24, alkyl groups or the like substituted on the same N atom may bond to each other to form a ring. The values of a to d are each 0 or 1. X? is a monovalent anion. In formula (2), Ar1 to Ar12 are each a substituted or unsubstituted aryl group. M? is a monovalent anion.

Abstract: A catalyst for producing unsaturated aldehyde and unsaturated carboxylic acid, wherein the cumulative pore volume (A) of pores having a pore diameter of 1 ?m or more and 100 ?m or less, in the catalyst, is 0.12 ml/g or more and 0.19 ml/g or less, and the ratio (A/B) of the cumulative pore volume (A) to the cumulative pore volume (B) of pores having a pore diameter of 1 ?m or more and 100 ?m or less, in a pulverized product not passing through a Tyler 6 mesh, in a pulverized product obtained by pulverization of the catalyst under a particular condition is 0.30 or more and 0.87 or less.

Abstract: An object of the present invention is to provide a catalyst ensuring that in the case of causing gas-phase catalytic oxidation of an unsaturated aldehyde and an oxygen-containing gas with use of the catalyst to produce a corresponding unsaturated carboxylic acid, the pressure loss can be kept low and an unsaturated carboxylic acid can be produced with high selectivity. The present invention relates to a ring-shaped or columnar catalyst, which is used at the time of producing a corresponding unsaturated carboxylic acid by causing gas-phase catalytic oxidation of an unsaturated aldehyde and an oxygen-containing gas, wherein the outer peripheral edge part is inclined relative to the center line.
