    摘要: A useful evaluation method which enables highly efficient production of a partially fluorinated alumina having good catalytic activities is discovered, and a method for isomerizing an organic compound whereby it becomes possible to improve a conversion rate in the desired isomerization reaction is provided. The method for isomerizing an organic compound comprises a step of selecting an alumina so that the acid amount calculated from the amount of ammonia desorbed at a desorption temperature of at least 300° C. by temperature-programmed desorption of ammonia is at least 0.10 mmol/g and at most 0.25 mmol/g; a step of fluorinating the selected alumina by a fluorinating agent to produce a partially fluorinated alumina; and a step of isomerizing, by using the obtained partially fluorinated alumina, an organic compound having at least two carbon atoms wherein to at least one of the adjacent carbon atoms, at least one fluorine atom is bonded and to the other, at least one chlorine atom or hydrogen atom is bonded.

    摘要: A method for producing 1234Z from 1234E while generation of 245fa as a byproduct is suppressed. The method for producing cis-1,3,3,3-tetrafluoropropene includes putting trans-1,3,3,3-tetrafluoropropene into contact with a catalyst. The trans-1,3,3,3-tetrafluoropropene is put into contact with the catalyst at a reaction temperature of higher than or equal to 200° C. and lower than or equal to 550° C. for a contact time of longer than or equal to 0.01 seconds and shorter than or equal to 500 seconds.
