Abstract


This research proposes the synthesis of SO4
2-/TiO2 heterogeneous catalysts and their application to the manufacture of
biodiesel from palmitic fatty acid through the esterification chemical reaction pathway using ethanol. This SO4
2- / TiO2
material performs as a super acidic heterogeneous catalyst. This catalyst, has demonstrated its performance in the
esterification reaction of palmitic acid into a palmitic acid ester with a conversion of 97.09%. The SO4
2- / TiO2 material
is a heterogeneous catalyst that can be applied in the processing of biodiesel from raw materials with high free fatty acid
content. This has an effect on improving the mastery of biodiesel production technology. In addition, the catalyst
material is environmentally friendly and economical so it can contribute to the increase of national energy security. The
research activity begins with catalyst synthesis, followed by applying the catalyst to the esterification chemical reaction.
The ester analysis obtained using GC-MS and obtained ester product 97,09%. Analysis of biodiesel properties for
viscosity at 40 ° C and density at 15 ° C obtained 2.051 mm2 / s (cSt) and 0.8448 g / cm3.
