Abstract: There is provided an industrially advantageous and efficient method of producing a Z-isomer of HCFO-1224yd or HCFO-1223xd by isomerizing an E-isomer thereof. The method produces HCFO (Z-isomer) by causing specific HCFO (E-isomer) contained in a raw material composition to undergo an isomerization reaction under a condition where the HCFO (E-isomer) is isomerized.
