Process for producing a polyglycidylamino compound characterized by comprising:
(I) an addition reaction step at which a diamine is reacted with an excess amount, based on diamine, of an epihalohydrin in the presence of water,
(II) a primary dehydrohalogenation reaction step at which the addition reaction mixture from the step (I) is reacted with a halogen-removing agent in the co-presence of at least one phase transfer catalyst,
(III) a step at which the dehydrohalogenation reaction mixture from the step (II) is separated into an organic phase and a water phase by adding water thereto, and an unreacted epihalohydrin is distilled off from the organic phase,
(IV) a step at which the reaction mixture from the step (III) is washed with water,
(V) a secondary dehydrohalogenation reaction step at which the crude polyglycidylamino compound from the step (IV) is reacted with a halogen-removing agent in the co-presence of at least one phase transfer catalyst, and
(VI) a step at which the dehydrohalogenation reaction mixture from the step (V) is washed with water.
