Sintesis Bioaditif Melalui Asetalisasi Gliserol Menggunakan Katalis Basolite F300
Abstract
Biodiesel transesterification process yields glycerol as by-product, accounting for 10 % of the total biodiesel production. Crude glycerol remains untreated and can cause severe environmental issues as it disposes directly. Catalytic conversion may be the best solution to convert crude glycerol into high value-added chemicals. A batch process was carried out for glycerol acetalization to produce solketal, an oxygenated fuel additive, by reacting glycerol and acetone through heterogeneous acid-catalyzed reaction using Basolite F300. The objective of this research is to investigate the effect of temperature, mole ratio of reactants, stirring speed and catalyst loading. Process optimization was performed under various experimental conditions. Solketal synthesis using crude glycerol from biodiesel production was also studied. The obtained results reveal that, in general, increasing the value of all parameters varied gave rise to the increasing of glycerol conversion. The optimum conditions were achieved when 500C, 700 rpm, 1:4 mole ratio of reactants, and 1 % (w/w) catalyst were used, exhibited 84.33 % of glycerol conversion. However, a different result was observed, the conversion was only 14.83 % when using waste glycerol as reactant.
