Abstract

In this paper, polysalisylaldehyde (PSA) has been synthesized from the oxidative polycondensation (OP) of 2-[(2,4-dichlorophenylimino)methyl]-phenol (sal-2,4-Clan) with NaOCl in an aqueous alkaline medium between 50 and 90Â°C and characterized by 1H-NMR, FT-IR, UV-Vis and TGA/DTA techniques. The conversion of PSA was 61.23% in optimum conditions such as [sal-2,4-Clan]0 = 0.02, [KOH]0= 0.1 [NaOCl]0 = 0.12 mol/L at 90Â°C for 10 h. Additionally, the crystal structure of sal-2,4-Clan has been determined by single-crystal X-ray crystallography.
