Özet
The bleaching process for sunflowerseed oil follows a rate formula, log (A/A(0)) = -k root t, according to absorbance measurements. The dark color of crude oil converts to a light color as the absorbance value decreases. The activation energy E-a was calculated from the Arrhenius equation as 3 kJ, and other activation thermodynamic parameters were determined as Delta S-not equal = -4.4 J K-1, Delta H-not equal = -31.2 J mol(-1), and Delta G(not equal) = 1.6 kJ mol(-1). The study showed that the bleaching process was exothermic, presented a decrease of entropy, and was a non-spontaneous process during activation.
