D-optimal design optimization of jatropha curcas L. seed oil hydrolysis via alkali-catalyzed reactions

Potassium hydroxide (KOH)-catalyzed reactions were utilized to hydrolyze Jatropha curcas seed oil. In this study, the effect of ethanolic KOH concentration, reaction temperature and reaction time to the free fatty acid (FFA) produced were investigated. D-Optimal Design was employed to study the sign...
