Abstract: PROBLEM TO BE SOLVED: To provide a method for suppressing the biased flow of liquid phase without using a device such as a liquid distributer or a porous material in a packed column-type chemical device.SOLUTION: In the method for moving and/or reacting the liquid phase having a step 1 for surface-treating solid particle and a step 2 in which the liquid phase comes in contact with the surface-treated particle in the packed column after the step 1, the content ratio of the particle having particle size of 0.09 mm or less is 0 to 33 mass% and the content ratio of the particle having particle size larger than 16 mm is 0 to 33 mass% in the particle size distribution of the solid particle. The liquid phase is hydrophilic liquid 1, and the surface-treatment includes a step of bringing the surface of the solid particle into contact with the hydrophilic liquid 2 and a step of drying the hydrophilic liquid 2. In the surface treatment, a spread area increasing ratio is 10 to 10,000% calculated by a standard examination.

Abstract: PROBLEM TO BE SOLVED: To make a catalyst for decomposing a gaseous fluorine compound maintain high decomposition performance for a long time under reaction conditions by being composed of a perfluoro compound in which γ-alumina is added with at least one metal selected from V, Nb, and Ta and a chlorofluorocarbon compound. SOLUTION: A catalyst contains the largest number of strong acid points, uses γ-alumina which indicates high activity in the decomposition of a fluorine compound, and is composed of a perfluoro compound in which at least one metal selected from V, Nb, and Ta which uses a metal salt such as a chloride, a sulfate, an oxalic salt or an oxy salt, an alkoxide, an organometalic complex for the γ-alumina by an impregnation method and a chlorofluorocarbon compound. In this way, since high decomposition activity can be maintained for a long time by the γ-alumina catalyst for the decomposition reaction of a perfluoro compound the decomposition of which is more difficult than that of a chlorofluorocarbon, a catalytic decomposition method of a fixed bed passage system is made possible.

Abstract: PROBLEM TO BE SOLVED: To provide a new improved method for producing biphenyls by which the biphenyls especially the biphenyls having asymmetrical substituents such as a tetraester of 2,3,3',4'-biphenyltetracarboxylic acid are selectively produced by oxidatively coupling benzene-based aromatic compounds, especially the aromatic compounds having substituents such as a diester of phthalic acid. SOLUTION: The benzene-based aromatic compound, especially the aromatic compound having substituents such as the diester of the phthalic acid are oxidatively coupled in the presence of a palladium salt, a copper salt and a bidentate compound foaming a complex of the palladium salt with a nitrogen atom and an oxygen atom, in an atmosphere containing molecular oxygen.
