dc.description.abstract | In this study citronellal conversion has been carried out into isopulegol through
the mechanism of cyclization reaction with precurso type of ZrO2/SiO2 catalyst.
Citronellal was isolated from lemon grass oil with a reduced pressure
fractionation distillation method. Citronellal with the highest levels was
obtained in fraction III with a pressure of 10 kpa, which was 20.23%.
characterization of precursors of ZrO2 / SiO2 catalysts was carried out by XRD,
BET analysis and acidity analysis using FTIR. The product characterization of
the reaction was carried out using gas chromatography (GC) based on the
results of the study. Cytronelal conversion to isopulegol was carried out using
precursors of ZrO2/SiO2 catalysts and time variations for each precursor type.
The highest isopulegol level was obtained at 2 hours reflux time of 99.72% by
using the precursor type of ZrOCl2. Cytronelal cyclization into isopulegol was
carried out using a variety of precursor types. Where isopulegol with the highest
level is obtained by using the type of precursor from ZrOCl2. That is produced
by Isopulegol as well as 99.72%. | en_US |
