Abstract

Characterisation and catalytic ativities investigation of modified natural zeolite on cyclisation acetylation reaction of (R)-(+)-citronellal was performed. The experimental work involved isolation of (R)-(+)-citronellal from Java Citronella oil (Cymbopogon winterianus) by vacuum fractional distillation, determination of its enantiomer, preparation and characterisation of different catalysts i.e. H-natural zeolite (H-Za), Fe3+-natural zeolite (Fe3+-Za), and Zn2+-natural zeolite (Zn2+-Za), followed by examination of catalytic activity and selectivity. Isolated citronellal contained 88.21% ee of (R)-(+)-citronellal. The main products of cyclisation-acetylation of (R)-(+)-citronellal was IPA (isopulegyl acetate) and NIPA (neo-isopulegyl acetate). Although the highest yield of IPA and NIPA was obtained by Fe3+-Za catalyst (78.69%) at 80oC and 120 min, the stereoselectivity of Fe3+-Za slightly lower than that of Zn2+-Za. Structure elucidation of citronellal and products was carried out by means of GC and GC-MS. Lewis acidity plays the role of acetyl ionic formation from acetic anhydride. The Activity and stereoselectivity of catalysts depended on Lewis acidity and cation distribution on the catalyst surface. © 2014 BCREC UNDIP.

Abstract

Natural Turen bentonite has been modified and applied as catalyst for palmitic acid esterification. Modification of natural Turen bentonite was conducted by cation exchange method using AlCl3 solution. Catalyst characterization was performed on X-ray Fluoroscence, X-ray Diffraction, nitrogen adsorption-desorption and infrared spectroscopy techniques. The catalytic activity test in the esterification reaction of palmitic acid with methanol was conducted by bath at 65 °C with a variation of reaction time of 1, 2, 3, 4 and 5 h. Catalytic activity has been observed qualitatively using GC-MS and quantitatively by changes in acid number. The analysis showed the formation of Al3+-bentonite. Observation on the elements has shown that the presence of calcium decreased from 10.2% to 4.17%, with an increase of aluminium content from 9.9% to 13%. Diffraction line at 2θ 5.7379º became 5.6489º, along with changes in d-spacing of 15.3895 Å to 15.6319 Å. The surface area increased from 83.78 m2/g to 91.26 m2/g, while Brönsted acid sites increased from 10.2 µmol/g to 67.5 µmol/g and Lewis acid sites increased from 94.9 µmol/g to 132 µmol/g. Furthermore, Al3+-bentonite has showed as active catalyst in the esterification reaction of palmitic acid with palmitic acid with conversion of 78.78% for 5 h. © 2014 BCREC UNDIP.
