SYNTHESIS OF 2-OXY-1-NAPHTHALDEHYDE SCHIFF BASES: ANALYSIS OF PHYSICO-CHEMICAL PROPERTIES AND SPECTROSCOPIC RESULTS
Main Article Content
Abstract
In the article, new Schiff bases of 2-oxy-1-naphthaldehyde were synthesized as a result of the condensation reaction with some primary amines of different structures. Physico-chemical properties of new Schiff bases were studied. The purity of 2-oxy-1-naphthaldehyde Schiff bases was determined by thin-layer chromatography and high-performance liquid chromatography. In determining the chemical structures of substances, it was analyzed by means of comparative comparison using modern spectroscopy methods. In the ultraviolet spectrum, 446 nm and 468 nm are characteristic of π→π* electron transitions, and absorption maxima, which were not observed in the starting substances, were observed. In the infrared spectrum, the deformation vibrations of С-Н bonds in the aromatic ring were shown at 793 cm-1, 742 cm-1. In addition, at 653 cm-1 vibrational frequencies corresponding to C=N bonds of the Schiff basis were observed.
