First Photolysis of Benzidine Schiff Base in Non Aqueous Solvents

Sulaiman G. Muhamad

Abstract


The first photolysis of synthesized Schiff base [Bis-(2-chlorobenzalidene) benzidine] in the presence of various
solvents (methanol, acetonitrile and n-hexane) was carried out under UV-light radiation. The data obtained by
UV-Visible spectroscopy was used to determine the kinetic parameters of the Schiff base photolysis. It was found
that the degradation of Schiff base in all solvents followed a first order reaction. The results show the rate of
photolysis depends on the polarity of solvents. The effect of temperature on the photolysis process in methanol has
been studies at different temperature ranging from 10ºC to 50ºC. The activation energy has been determined. The
intermediates formed in the Schiff base photolysis processes were detected and identified, using High Performance
Liquid Chromatography analytical technique coupled with UV-visible spectrophotometer.
