Synthesis and charactreization of azo and Schiff base new compounds based on 2-amino 3- hydroxi pyridine and their complexes with Co ls and investigation of their conversion to nano materials

2-Amino-3-Hydroxy Pyridine (AHP) was reacted with aniline in the presence of (NaNO2) and concentrated HCl and NaOH(10%) to produce azo compounds(-N=N-). The new Schiff base compounds were prepared by the reaction of them with two different aromatic aldehides, namely: therphetaldehide and 5-bromosalicylealdehide. The new complexes of Co(II)acetate have been synthesized and characterized in water and alcohol. The thermal stability of nano-structure Co( II ) was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). CoO nano powders have been optained by calsinations of the compounds at 750°C for 2h and characterized by FT-IR spectroscopy, X-ray powder determined and SEM.
