Title:
パーフルオロシクロアルケン化合物の製造方法
Document Type and Number:
Japanese Patent JP6753443
Kind Code:
B2
Abstract:
A perfluorocycloalkene compound represented by formula (1) [in the formula, R1-R4 are the same or different and represent a fluorine atom or a perfluoroalkyl group] is obtained at a high yield and high selectivity as well as a high reaction conversion rate by subjecting a perfluoroalkadiene compound represented by CR1 2=CR2-CR3=CR4 2 [in the formula, R1-R4 are the same or different and represent a fluorine atom or a perfluoroalkyl group] to a cyclization reaction. The cyclization reaction can be carried out in the presence of a catalyst, by a gas-phase flow continuous system, or both in the presence of a catalyst and by a continuous gas-phase flow system.
