| Abstract: | Taking hexane and cyclohexane as inert diluent, 1:1 complex equilibrium constants for the N-methylpyrrolidone complexes with styrene, o-xylene, m-xylene and p-xylene have been determined in ultraviolet range by Spectrophotometric method. These equilibrium constants can be used to make qualitative indication of strength of weak chemical interaction. |
