Abstract
To confirm the advantage for synthesis of Schiff base using jet milling, Schiff base derived from p-chlorobenzaldehyde and p-aminobenzoic acid was synthesized using jet milling. The 1H NMR and FTIR technology confirmed the structure of Schiff base. Optimized geometrical structure showed that the HOMO and LUMO of Schiff base were -9.16 eV and -1.256 eV, respectively. And that the HOMO of Schiff base focused on benzene, in contrast, the LUMO of Schiff base was dispersed. The bond length and bond angle between atoms at imine group was smaller than that of other group.
