A PROCESS FOR PREPARATION OF AN AROMATIC N-GLYCIDYLAMINE
A process for preparing an aromatic N-glycidylamine comprising a step of heating a mixture of an amine having at least one aromatic aminohydrogen atom with at least 0.7 equivalent of epichlorohydrin per aminohydrogen equivalent of the amine in presence of a catalyst dissolved in an inert organic solvent, at a pressure in a range of 200 mbar to 600 mbar; and adding a base to the mixture at a pressure in a range of 200 mbar to 600 mbar to facilitate dehydrochlorination of product of the previous step to obtain the aromatic N-glycidylamine.

Manufacturing method for compound having N,N-bis(2-hydroxy-3-chloropropyl)amino group
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.sup.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.

Nucleophilic substitution of carbon nanotubes
Compounds are attached to carbon nanotubes (CNT) by a process which comprises: subjecting surface treated CNTs which have been treated to induce negatively charged surface groups thereon, to nucleophilic substitution reaction with a compound carrying a functional group capable of reacting with the negatively charged groups on the CNT surface, whereby the compound chemically bonds to the CNT. The surface CNT treatment may be reduction. The compounds which are bonded to the CNT may be epoxy resins, bonded directly or through a spacer group. Bi-functional CNTs, grafted to both epoxy resins and other polymers such as polystyrene, are also made by this process.
