Abstract
The present invention provides a method for producing a fluorine-containing haloolefin compound, said method being able to reduce the generation of overly fluorinated compounds as by-products in the production of the fluorine-containing haloolefin compound and produce the target product of high purity at a high yield. The invention also provides a halogenated hydrocarbon composition. The method for producing a haloolefin compound through the step of fluorinating a starting material containing at least one of a pentachloropropane or a tetrachloropropene in the presence of a fluorinating agent in a reactor, according to the present invention, includes the step of adding hydrogen chloride to the reactor. The composition according to the present invention contains: at least one member selected from the group consisting of a pentachloropropane and a tetrachloropropene; and hydrogen chloride.
