    Abstract: PROBLEM TO BE SOLVED: To provide a catalyst having excellent characteristics, and to provide a production method of an aromatic polyamine mixture.
    SOLUTION: The production method of an aromatic polyamine mixture comprises, for producing aromatic polyamine mixtures containing the compound of formula (I), reacting a compound of formula (IV) and/or a compound of formula (V) at 20-200°C in the presence of a heterogeneous inorganic catalyst selected from the following groups: (b) montmorillonite which is doped with at least one element of group 2, group 3, group 4, group 7 or group 13 or an oxide of lanthanide and may be acid-activated and (c) one or more sheet silicates having an acidity of ≥0.05 mmol/catalyst g at
    p K
    a =1.5 and selected from the group consisting of montmorillonite and sepiolite (these may be acid-activated) and attapulgite. Formula (I): H
    2 N-A-CH
    2 -B-NH
    2 . Formula (IV): H-A-NH-CH
    2 -HN-B-H. Formula (V): H-A-NH-CH
    2 -B-NH
    2 (Wherein, A and B are each independently a 1-4C phenylene group which may have 1-4 substituents selected from a 1-20C alkyl group and a halogen).
