دراسة ثرموداينميكية وتوتومرية للسالسيليدين بارا-نايترو أنلين

Abstract

This research involve studying the factors affecting tautomeris form equilibrium of Salicylidene P-Nitro aniline (I), the effect of solvent (polar or non polar) like ethanol ,acetone and benzene, as well as, The change of concentrating , PH (from 4-10), and temperature (from 288-318 K) in UV& IR.Were investigated thermodynamic changes in different temperatures,show non- spontaneous (+G), endothermic (+H) processaccompanied by a decrease in the disorder of the system(-S).
