Abstract
Sintesis katalis magnesium fluorida terdoping Ni (Mg0,95Ni0,05F2) dengan metode sol gel dan optimasi reaksi katalitik untuk pembentukan metil oleat telah diteliti. Katalis dikarakterisasi dengan difraksi sinar-X dan FTIR. Hasil karakterisasi menunjukkan bahwa terjadi proses doping Ni pada katalis MgF2, dan nilai sisi asam Lewis dan Brønsted, SBET, dan volume pori masing-masing sebesar 0,117; 0,047; 12,97 m2/g dan 0,093 cm3/g. Kinerja katalis telah diuji pada esterifikasi asam oleat dengan metanol menjadi metil oleat dengan mengoptimalkan beberapa faktor yang mempengaruhi reaksi yaitu suhu, waktu, dan konsentrasi katalis. Hasil penelitian menunjukkan bahwa kinerja katalis (Mg0,95Ni0,05F2) untuk produksi metil oleat optimum pada suhu 150°C, waktu reaksi 120 menit, konsentrasi katalis terhadap asam oleat 6% dengan konversi FFA 77,63%. Massa jenis, titik nyala, pH dan warna metil oleat menurut ASTM D 6751 dan SNI 7182:2015 masing-masing adalah 0,8739 g/cm3, 104°C, 6 dan 3,586.

Nickel-doped magnesium fluoride catalyst (Mg0,095Ni0,05F2) synthesis by sol gel method and optimization of the catalytic reaction for the formation of methyl oleate have been investigated. The catalyst was characterized by X-ray diffraction and FTIR. The characterization results showed that the Ni doping process in the MgF2 catalyst occurred, and the Lewis and Brønsted acid side values, SBET, and pore volume were 0,117; 0,047; 12,97 m2/g and 0.093 cm3/g respectively. The performance of the catalyst has been tested on the esterification of oleic acid with methanol into methyl oleate by optimizing several factors that affect the reaction, namely temperature, time, and catalyst concentration. The results showed that the optimum catalyst performance was at a temperature of 150°C, reaction time of 120 minutes, 6% catalyst concentration of oleic acid with FFA conversion 77,63%. Density, flash point, pH and color of methyl oleate according to ASTM D 6751 and SNI 7182:2015 are 0,8739 g/cm3, 104°C, 6 and 3,586 respectively.
