Abstract
Catalytic transformation of 1,8-cineole from Cajeput oil was studied with Fe3+-Zeolite beta and Ni3+-Zeolite beta catalysts. 1,8-Cineole was obtained by fractional distillation under reducing pressure of Cajeput oil from Gundih Purwodadi. Preparation of Fe3+-Zeolite beta and Ni2+-Zeolite beta catalysts was conducted by ion exchange and calcination, followed by catalytic activity test on aromatization of 1,8-cineole reaction in acetic anhydride. Optimization of reaction condition was studied with variation of temperature, reaction time and reactant mole ratio. The purity of 1,8-cineole isolated from Cajeput oil was 84.81%. The best total activity and selectivity of Fe3+-zeolite beta catalysts were obtained by molar ratio [SIN]/[AA] 1:4 at reaction times of 720 minutes of 69.66% and 20.47% respectively.
