Abstract

Pada penelitian ini telah dilakukan sintesis katalis Mg1-xZnxF2 (x= 0,025; 0,05; 0,10 dan 0,15) dengan metode sol-gel. Katalis dikarakterisasi dengan difraksi sinar-X (XRD) dan adsorpsi piridin-FTIR Aktivitas katalitik katalis diuji pada reaksi minyak RPO (Refined palm Oil) dan metanol. Hasil XRD menunjukkan bahwa semua katalis Mg1-xZnxF2 memiliki kecocokan struktur dengan database MgF2 tetragonal. Semua katalis Mg1-xZnxF2 memiliki sisi asam Lewis dan asam Brønsted pada spektra FT-IR. Aktivitas tertinggi diperoleh pada katalis Mg0,95Zn0,05F2 dengan konversi asam palmitat dan asam stearat masing-masing sebesar 3,6% dan 37,06% dan konversi total sebesar 40,66%. =====================================================================================================\ Mg1-xZnxF2 (x= 0,025; 0,05; 0,10 dan 0,15) catalysts were synthesized by a sol-gel method. The catalysts were characterized by X-ray diffraction and FT-IR pyridine adsorption method. The catalytic activity of the samples were tested by Refined Palm Oil (RPO) and methanol reaction. The result of XRD pattern showed that the structure Mg1-xZnxF2 catalysts match with MgF2 tetragonal database. Mg1-xZnxF2 catalysts have a Lewis and Brønsted acid from FT-IR spectra. The best results of catalytic testing were obtained by Mg0,95Zn0,05F2 catalyst with conversion of palmitat acid and stearat acid 3,6% and 37,06% respectively and total conversion is 40,66%.
