  • Publication number: 20160185722
    Abstract: A method for producing meta-xylylenediamines includes a reaction step in which monohalogenated benzenes, formaldehydes, and an amide compound having a primary amide group or a secondary amide group are allowed to react in the presence of an acidic liquid, a dehalogenation step in which the halogen atom derived from the monohalogenated benzenes is replaced with a hydrogen atom, and a deprotection step in which the primary amide group or the secondary amide group derived from the amide compound is converted to an amino group. In the reaction step, the acidic liquid contains inorganic acid, the equivalent ratio of the hydrogen atom of the inorganic acid relative to the monohalogenated benzenes is more than 16; the acidic liquid has an inorganic acid concentration of more than 80 mass %; and the reaction temperature is more than 40° C.
