Abstract | 나트륨 함유량이 많은 알루미나를 함유하는 촉매를 사용했다고 해도, (E)-1,1,1,4,4,4-헥사플루오로-2-부텐을 고수율로 얻을 수 있는 제조 방법을 제공한다. (E)-1,1,1,4,4,4-헥사플루오로-2-부텐의 제조 방법은 알루미나를 함유하는 촉매에 (Z)-1,1,1,4,4,4-헥사플루오로-2-부텐을 접촉시켜서, (Z)-1,1,1,4,4,4-헥사플루오로-2-부텐을 (E)-1,1,1,4,4,4-헥사플루오로-2-부텐으로 이성화하는 이성화 공정을 구비한다. 알루미나는 복수의 세공을 갖는 다공질체이며, 중심 세공 지름이 5nm 이상 40nm 이하이다. 다공질체가 갖는 모든 세공 중, 중심 세공 지름의 -50% 이상 +50% 이하의 범위 내의 세공 지름을 갖는 세공의 합계의 용적의 비율이, 전 세공 용적에 대해서 70% 이상이다.
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. |
