Transesterifikasi Minyak Limbah Ikan Patin Menggunakan Isobutanol dengan Variasi Jumlah Katalis dan Waktu Reaksi

Abstract

Plastisizer is an organic solvent with high boiling point. Which had low meltingpoint. Plastisizer is produced from process called transesterification. It is a reaction between oil (ester) and alcohol, creating new esters and glycerol as it’s by products.This experiment used waste of cat fish oil, isobutanol as solvent, and H-Zeolit ascatalyst. The transesterification is performed in a reactor equipped with mixer.Independent variables were set prior to the study, consists of molar ratio 1:6, mixervelocity 175 rpm, and temperature of 90°C. While the dependent variables arereaction rate of 5, 6, and 7 hours, and respectavallly catalyst amount 10%, 15%,and 20% of oil weight. This experiment resulted in plastisizer with similarcharacteristics to commercial plastisizer in specific gravity, viscosity, except sapo-nification value. Furthermore, at reaction rate 6 hours and catalyst amount of 15%,the conversion of 18,03%.
