Abstract
Silika tersulfat telah berhasil disintesis dengan metode impregnasi basah. Variasi yang digunakan adalah jumlah asam sulfat dalam toluena. Padatan dikarakterisasi dengan teknik spektroskopi inframerah, diffraksi sinar-X, dan keasaman permukaan. Uji aktivitas katalis dilakukan pada reaksi esterifikasi asam oleat dengan metanol dengan rasio molar 1:30 selama 5, 10, 15, 30 dan 60 menit. Hasil penelitian menunjukkan bahwa silika tersulfat merupakan padatan amorf dengan keasaman tertinggidan aktivitas katalis terbaik pada katalis 60S/MK dengan nilai konversi mencapai 94,12% untuk waktu reaksi selama 60 menit

Sulfated silica has been synthesized by wet impregnation method. Variation used was the amount of sulfuric acid in toluene. The catalysts were characterized byinfrared spectroscopic, X-ray diffraction and surface aciditytechniques. Catalyst activity was testedin the oleic acid esterificationwith methanol at a molar ratio of 1:30 for 5, 10, 15, 30 and 60 minutes. The results showed that sulfated silica is an amorphous solid withthe highest acidity and the best catalyst activitywas observed in60S/MK catalyst with a 94,12% conversionfor 60 minutes of reaction time
