Optimization of Linoleic Acid Monoepoxidation Condition from Malaysian Jatropha curcas Using Central Composite Design (CCD)

Abstract

The aim of this study was to optimize the monoepoxidation process of linoleic acid obtained from Malaysian Jatropha curcas oil using central composite design (CCD). There were four independent variable factors had been studied which involved reaction temperature (X1), reaction time (X2), catalyst loading (X3) and H2O2 concentration (X4). Thirty experiments were carried out based on the experimental design responses obtained. The results showed that the optimum condition was obtained at catalyst loading of 0.11% (w/w) methyltrioxorhernium (VII) (MTO), H2O2 mole of 99%, reaction temperature of 58.41oC for 5 hours. The central composite design was proven to be simpler method, time saving and required less samples compared to the conventional method.
