Abstract

Pada penelitian ini telah dilakukan sintesis katalis Fe2O3 dan Mg1-xFexF2 (x= 0; 0,025; 0,05; 0,075; 0,10 dan 0,15 mol) dengan metode sol-gel. Katalis dikarakterisasi dengan difraksi sinar-X (XRD) dan adsorpsi piridin-FTIR. Aktivitas katalitik katalis diuji pada reaksi transesterifikasi antara Refined Palm Oil (RPO) dengan metanol. Hasil XRD menunjukkan bahwa katalis Mg1-xFexF2 berhasil disintesis karena logam Fe masuk ke dalam struktur MgF2. Semua katalis menunjukkan pita serapan sisi asam Lewis dan Brǿnsted dari kompleks piridin. Hasil terbaik dari uji katalitik diperoleh katalis Mg0,9Fe0,1F2 dengan total konversi 71,78%.
==============================================================================================================================
Fe2O3 and Mg1-xFexF2 (x= 0; 0,025; 0,05; 0,075; 0,10 and 0,15 mol) catalysts were synthesized by a sol-gel technique. The catalysts were characterized by X-ray diffraction and FT-IR pyridine. The catalytic behavior of the samples were tested by Refine Palm Oil (RPO) with methanol transesterification reaction. The result of XRD pattern showed that the structure of Mg1-xFexF2 successful because metal Fe into the structure of MgF2. All the systems showed Lewis and Brǿnsted acid band in the FT-IR of pyridine complexes. The best results of catalytic testing were obtained by Mg0,9Fe0,1F2 catalyst with conversion 71,78%.
