Abstract

PRODUCTION OF PROCESS OF METHYL ESTER FROM MAHOGANY SEED OIL WITH IN SITU TRANSESTERIFICATION USING CO-SOLVENT THF (TETRAHYDROFURAN). The purpose of this research was to assess the effectiveness of the use of co-solvent THF for in situ transesterification reaction mahogany seed oil. Mahogany seeds which have been dried and pulverized size +20/-30 mesh around 50 grams. The pulverized seeds were inserted in to three-neck flask equipped with condenser. Methanol, THF and catalyst NaOH were added to the flask then the reaction was carried out with the certain variables and operating conditions. After the reaction was complete then the filtrate and cake were separated. To stop the reaction with neutralized the NaOH catalyst with added HCl 1 mol/L to pH 4. The filtrate was distilled at a temperature of 70°C and the residue placed separating funnel and allowed for 12 hours in order to obtain two layers. The top layer as methyl ester was analyzed by GC as concentration of methyl ester. According to the result was obtained that the best results of this process achieved at a molar ratio of oil to THF of 1: 67.85 and reaction time of 23 minutes with methyl ester concentration of 69.28% and methyl ester yield of 67.95%. Methyl ester density attained at 0.8791 g/cm3 regards with SNI 04-7182-2006. Keywords: biodiesel; co-solvent; in situ transesterification; mahogany seed oil
