    Abstract: 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.

    Abstract: To provide a method for producing a fluorovinyl ether compound, whereby it is possible to suppress the generation of byproducts. The method for producing a fluorovinyl ether compound of the present invention is a method for producing a fluorovinyl ether compound, which comprises heat-treating a compound having a group represented by the formula (1): F—C(═O)—CF(X)—(CF2)n—O— in the presence of an oxide containing at least one element selected from the group consisting of alkali metal elements and alkaline earth metal elements, to obtain a fluorovinyl ether compound having a group represented by the formula (2): CF2═CF—O—, wherein the specific surface area of the oxide before the heat treatment is at least 1.0 m2/g. In the formula (1), n is 0 or 1, wherein when n is 0, X is CF3 and when n is 1, X is F.
