摘要：
A method for isomerizing a hydrohalofluoroolefin isomer to produce a corresponding hydrohalofluoroolefin isomer includes a step contacting a composition that contains at least a hydrohalofluoroolefin isomer and that has been adjusted to 100 ppm or lower in moisture concentration, with a catalyst in a gas phase, thereby obtaining a product. This method makes it possible to suppress the catalyst performance lowering.
