Title:
METHOD FOR PRODUCING HALOGENATED BUTENE
Document Type and Number:
WIPO Patent Application WO/2020/170980
Kind Code:
A1
Abstract:
A method for producing a halogenated butene compound represented by CX1X2X3CX4=CHCX7X8X9 [In the formula, X1, X2, X3, X4, X7, X8 and X9 are identical or different and represent halogen atoms.], the method being equipped with a step for reacting a hydrogen halide with a halogenated butyne compound represented by CX1X2X3C≡CCX7X8X9 [In the formula, X1, X2, X3, X7, X8 and X9 are the same as indicated above.] in the presence of a catalyst. This production method makes it possible to selectively obtain a butene compound which has seven halogen atoms at a high conversion ratio.
