Title:
HALOGENATED ALKENE COMPOUND AND METHOD FOR MANUFACTURING FLUORINATED ALKYNE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2020/171011
Kind Code:
A1
Abstract:
A halogenated alkene compound and a halogenated alkyne compound are obtained at a high conversion rate and selectivity by employing any of the following methods (1) through (4): (1) a halogenated butane compound represented by CX1X2X3CHX4CFHCX5X6X7 (where X1, X2, X3, X4, X5, X6, and X7 are the same or different, and are halogen atoms) is subjected to a dehydrofluorination reaction; (2) a halogenated butene compound represented by CX1X2X3CX4=CHCX5X6X7 (where X1, X2, X3, X4, X5, X6, and X7 are the same as above) is subjected to a dehydrohalogenation reaction; (3) a halogenated alkane compound represented by CHX8A1CHX9A2 (where A1 and A2 are fluorine atoms or perfluoroalkyl groups, and X8 and X9 are the same or different, and are halogen atoms) is subjected to a dehydrohalogenation reaction in a vapor phase in the presence of a catalyst; and (4) a halogenated alkene compound represented by CX8A1=CHA2 (where A1, A2, and X8 are the same as above) is subjected to a dehydrohalogenation reaction in the presence of a catalyst.
