Abstract

Telah dilakukan sintesis doping katalis Mg1-xNixF2 (x= 0,025; 0,05; 0,10 dan 0,15 mol) pada penelitian ini dengan metode sol-gel. Katalis dikarakterisasi struktur kristal dengan difraksi sinar-X (XRD) dan ditentukan keasaman adsorpsi piridin- FTIR dengan metode adsorpsi nitrogen. Aktivitas katalis diuji pada reaksi metilasi minyak kelapa sawit antara RPO (Refined Palm Oil) dan metanol. Hasil XRD menunjukkan bahwa katalis Mg1-xNixF2 berstruktur yang sama dengan database MgF2 yaitu tetragonal. Katalis Mg1-xNixF2 memiliki asam Lewis dan asam Brønsted dari spektra FTIR. Konversi asam palmitat dan asam stearat oleh katalis MgF2 diperoleh masing-masing 0,33% dan 13,73%. Hasil terbaik dari uji katalitik diperoleh katalis Mg0,85Ni0,15F2 dengan konversi terhadap asam palmitat dan asam stearat masing-masing sebesar 4,51% dan 76,21%. ============================================================================================================ In this studied, Mg1-xNixF2 (x= 0; 0,025; 0,05; 0,10 dan 0,15 mol) catalysts were synthesized by a sol-gel technique. The catalysts were characterized by X-ray diffraction and acidity was determined by FTIR-pyridine adsorption analysis. The catalytic behavior of the samples were tested by metilation reaction between RPO (Refined Palm Oil) and methanol. The result of XRD pattern showed that the structure of Mg1-xNixF2 match with MgF2 tetragonal database. Mg1-xNixF2 catalysts have a Lewis and Brønsted acid from FTIR spectra. Conversion of palmitate acid and stearate acid by MgF2 catalyst are 0,33% and 13,73% respectively. The best results of catalytic testing were obtained by Mg0,85Ni0,15F2 catalyst with conversion of palmitate acid and stearate acid are 4,51% and 76,21%, respectively.
