Abstract

the production of ethyl ester from the triglyceride molecules of used cooking oil via sodium hydroxidetransesterification was optimized using response surface methodology or RSM. The variables chosen were ethanol-to-oi molar ratio. NaOH-to-oil molar ratio, temperature and reaction time. The response was the purity of biodiesel,which was quantified using CP Atlas 2.0 Software. Through the response surface methodology, via Design Expert 9.0.4.1 trial version, the optimum conditions to meet the PNS standard for biodiesel purity were found to be 11.34:1 ethanol-to-oil molar ratio, 0.229:1 NaOH0to-oil molar ratio and 40.57ºC. These conditions were used in time profiling which showed that a minimum reaction time of 75 minutes, at least 96.5%
