The reaction process was monitored by HPLC, and the structures of related intermediates and products were identified by (1)H NMR, FT-IR and LC-MS techniques. The experiments proved that mono-Schiff base and bis-Schiff base could both be synthesized at the same time when o-phenylenediamine and aldehydes were in a molar ratio of 1 : 1, and the influences of the reaction were proposed.
