Abstract
The synthesis of an azo dye by
coupling the water extract of the fruit husk of Parkia
clappertoniana, a polyphenolic compound with diazonium salt was
attempted. A yellow dye soluble in water was obtained. The dye was
characterized using spectroscopic methods (infrared and ultraviolet)
and chromatographic analysis. Results obtained showed the
synthesized dye to have similar properties, which are characteristic
of conventional azo dyes. It is therefore deducted from these
findings that C. clappertoniana can serve as an alternative source
of raw materials for Azo dye production. |
