Assessment Of Two Local Plant Dyes As Colourants For Petroleum Products (Petrol, Kerosene And Diesel)

ABSTRACT

Dyes from Pterocarpus osun Craib and Lawsonia inermis Linn. were extracted

using ethanol and methanol respectively. The extracted dyes were subsequently

purified using chromatographic methods. Purified pigments were characterized

using Ultra-Violet Visible Spectrophotometer, Fourtier Transform Infrared

Spectrophotometer and Lovibond Tintometer. The UV spectra of the dyes in

petrol, kerosene and diesel showed presence of chromophores. The FTIR

spectra of the dyes showed presence of phenolic O-H stretching and C=C of

aromatic functional groups. The dye from Lawsonia inermis Linn. was

remarkably stable in colouring petrol for a period of twenty-eight days but not

in kerosene and diesel while the dye from Pterocarpus osun Craib was not

stable. Thus, dye from Lawsonia inermis Linn. can be used as alternative

source of colourant for petrol while the dye can not be used for the same

purpose for kerosene and diesel due to their instability. The dye from

Pterocarpus osun Craib cannot be used because of their instability. They are

not remarkably active in colouring any of the petroleum products (petrol,

kerosene and diesel).
