Optimization of chemical transesterification of palm oil using response surface methodology. - (:unkn) unknown (Medan : IOPRI, 1998)
The effect of catalyst concentration (0.1-0.5per cent), temperature (50-92C), and time (30-480 min) of chemical transesterification was studied to determine the optimun condition for maximizing concentration of triunsaturated and trisaturated triglyceride (TG) in palm oil. TG compositions of the oil were analysed using high performance liquid chromatography. The optimun condition of the process was determined using statistical response surface methology. The result show that the triunsaturated and trisaturated responses followed a second order form of the treatments with R20.83 and 0.85 respectively. Considering the two responses, it was concluded that the overall optimum condition was achieved at 0.36per cent of catalyst at 78-81C and 325-360 min reaction time. Such condition increased trisaturated triglyceride in palm oil by 2.34 times and triunsaturated by 1.54 times.
