Green Synthesis Of Isopulegol From Citronellal Catalysed By Zeolite Based Solid Acid Catalysts
Natural zeolite (NZ) was modified by acid treatment (H-NZ) and applied as a solid acid catalyst in the green synthesis of isopulegol from the essential oil of citronella. The synthesis involves a cyclisation reaction of citronellal to isopulegol at a temperature range of 50 to 120˚C. The catalytic activity of H-NZ was higher than that of the commercially available H-ZSM5 and much superior to bentonite based solid acid catalyst. The best yield of 87 persen isopulegol was obtained using the H-NZ catalyst at 100 ºC for 3 h without the use of any solvent. Jurnal Chimica et Natura Acta
