SPECTROPHOTOMETRIC STUDY OF THE THERMODYNAMICS AND KINETICS OF CHARGE-TRANSFER COMPLEXATION OF DIBENZO- 18-CROWN-6 WITH IODINE IN CHLOROFORM SOLUTION
The charge-transfer complexation reaction between iodine and dibenzo- 18-crown- 6 (DB18C6) has been studied spectrophotometrically in chloroform solution at different temperatures. The resulting donor-acceptor complex was formulated as (DB 18C6…I )I . The spectrophotometric results , as well as the conductivity measurements, indicated that the gradual release of tiiodide ion from its contac...

15 صفحه اولSpectroscopic analytical study for the charge-transfer complexation of certain cephalosporins with chloranilic acid.
Studies were carried out to develop a simple, rapid and accurate spectrophotometric method for the analysis of fifteen cephalosporins. The method depends on the charge-transfer complexation reaction between any of these drugs as an n-electron donor and p-chloranilic acid (p-CA) as a pi-acceptor to form a violet chromogen measured at 520 nm. Different variables affecting the reaction were studie...
