    摘要： The present invention relates to a catalyst having at least one peak in each of a range of a pore diameter of 0.45 µm to 10.0 µm and a range of a pore diameter of 0.040 µm to 0.45 µm in a pore distribution (-dV/d (log D) vs D) measured by mercury porosimetry, in which when a maximum value of -dV/d (log D) in the range of the pore diameter of 0.45 µm to 10.0 µm is represented by A and a maximum value of -dV/d (log D) in the range of the pore diameter of 0.040 µm to 0.45 µm is represented by B, (B/A) is 0.20 to 13.0 (V represents a volume (unit: mL/g) of filled mercury per sample weight, D represents the pore diameter (unit: µm), log D represents a natural logarithm of D, and -dV/d (log D) represents a reciprocal of a value obtained by differentiating a cumulative pore volume in a specific pore diameter range by a logarithm of the pore diameter).

    摘要： Provided is a method capable of producing (E)-1,1,1,4,4,4-hexafluoro-2-butene at a high yield even with a catalyst containing alumina having a large sodium content. The method for producing (E)-1,1,1,4,4,4-hexafluoro-2-butene includes an isomerization step of bringing (Z)-1,1,1,4,4,4-hexafluoro-2-butene into contact with a catalyst containing alumina to isomerize the (Z)-1,1,1,4,4,4-hexafluoro-2-butene to (E)-1,1,1,4,4,4-hexafluoro-2-butene. The alumina is a porous body having a plurality of pores and having a central pore size of 5 nm or more and 40 nm or less. The proportion of the total volume of pores having a pore size of not less than -50% and not more than +50% of the central pore size, of all the pores of the porous body, to the total pore volume of the porous body is 70% or more.
