Abstract

N,N‐bis(2,3‐epoxypropyl) aniline (N,N‐diglycidylaniline, DGA) and an intermediate of its synthesis, N,N‐bis(2‐hydroxy‐3‐chloropropyl) aniline (N,N‐dichlorohydrin of aniline, DCHA), were analyzed by GPC and HPLC. The main impurities were isolated by semipreparative HPLC and their structure was identified by mass, IR, and NMR spectroscopy. Attention was also paid to the mechanism underlying the formation of these impurities.

The course of intramolecular cyclization of N,N-bis ( 2-hydroxy-3-chloropropyl) aniline (DCHA) was followed by HPLC. The rate constants (at 70,85,100, and 115OC) and the Arrhenius parameters for individual reaction steps were determined. The resulting product was isolated by semipreparative HPLC and
