Abstract

CaOMgO telah disintesis dari serbuk kapur menggunakan metode kopresipitasi dengan NaOH 0,075 M dan Na2CO3 0,075 sebagai agen pengendap. Padatan hasil sintesis dikalsinasi dengan variasi suhu 500 700, dan 900ºC. Selanjutnya padatan dikarakterisasi menggunakan difraksi sinar-X (XRD) dan spektroskopi inframerah (FTIR). CaOMgO hasil sintesis kemudian digunakan sebagai katalis dalam reaksi transesterifikasi minyak kemiri sunan dengan metanol. Reaksi transesterifikasi dilakukan pada variasi rasio metanol minyak (9:1 ; 26:1 ; 54:1), variasi konsentrasi katalis (2, 4, 8 %berat minyak) dan variasi suhu kalsinasi katalis (500, 700, 900ºC). Kadar metil ester dianalisis menggunakan kromatografi gas (GC). Yield optimum diperoleh dari reaksi menggunakan rasio metanol minyak 9:1, konsentrasi katalis 2%, dan suhu kalsinasi katalis 900ºC sebesar 37%.

CaOMgO have been synthesized of lime powder using coprecipitation method with 0.075 M NaOH and Na2CO3 0.075 as precipitating agent. Solid were calcination in temperature variations (500, 700, 900 º C) to characterized using X-ray diffraction (XRD) and infrared spectroscopy (FTIR). CaOMgO are used as catalysts in oil transesterification with methanol and kemiri sunan oil. Optimation of yield can obtained from the transesterification reaction using variation ratio methanol oil (9:1; 26:1; 54:1), variations in the concentration of catalyst (2, 4, 8 wt% oil) and catalyst calcination temperature variations (500, 700, 900 º C). Methyl esters were analyzed using gas chromatography (GC). Results showed that the highest yield obtained from reaction using methanol oil ratio of 9:1, catalyst concentration of 2%, and the catalyst calcination temperature of 900 º C with 37% yield.
