A method efficiently and safely manufactures, on an industrial scale, a compound having an N,N-bis(2-hydroxy-3-chloropropyl)amino group. (1) an amine compound or a solution thereof, (2) epichlorohydrin or a solution thereof, and (3) an acidic compound or a solution thereof are continuously supplied to a flow reactor and reacted at a reaction temperature of 40 to 130° C. and a liquid space velocity of 0.2 to 10 h
−1
so that a compound having an N,N-bis(2-hydroxy-3-chloropropyl)amino group is manufactured. The obtained compound having an N,N-bis(2-hydroxy-3-chloropropyl)amino group is dehydrochlorinated by reaction with an alkali so that a polyfunctional glycidylamine type epoxy compound is manufactured.
A novel epoxy compound represented by the following formula and a method for producing the same are provided:
wherein R
1
and R
2
are members selected from the group consisting of hydrogen, aliphatic hydrocarbon group having 1 to 4 carbon atoms, alicyclic hydrocarbon group having 3 to 6 carbon atoms, aromatic hydrocarbon group having 6 to 10 carbon atoms, halogen atom, ether group, ester group, acyl group and nitro group, n is an integer of 1 to 4, and m is an integer of 1 to 5.
