Determination of Physical and Chemical Properties of Benzylidenanilines And their Polymer Analogues in Organic Solvents
Abstract: The physicochemical characteristics of monomeric azomethins, their polymer analogs and low molecular weight model compounds were studied. Derived from substituted aromatic amines and aldehydes in non-aqueous solvents: basicity, full exchange capacity for hydrogen, IR and UV spectra, and ability to complex. Measured pKa by semi-neutralization in dimethylformamide. Electronic effects are investigated. The effect of substituents on the characteristics of azomethins using s-constant Jaffe; it has been established correlation dependencies. The total exchange capacity of polyazomethines for hydrogen (POEН+) was determined by the method of inverse potentiometric titration; the correlation dependences of POEН+ on the s-constants of the substituents were established. The UV and IR spectra of mono- and polyazomethines and their complexes with Cu2+ ions were studied. The features of the influence of substituents on the position of the absorption bands in the UV and IR spectra are established.
Keywords: azomethines, polyazomethines, low molecular weight model compounds, inorganic solvent, UV- and IR-spectra, basicity, OEE, complexation.
