Abstract :

Anetol is the anise oil main content and can be transformed into their derivatives with a higher level of benefits. The objective of this research are use and to find out the catalytic activity of impregnated phosphomolybdic acid on bentonite (H3PMo12O40/bentonite) in anethole transformation. This research was started by making H3PMo12O40 catalyst which was impregnated into activated bentonite. Furthermore, H3PMo12O40/bentonite was characterized by XRD and FT-IR. Then, H3PMo12O40/bentonite was applied in anethole transformation at 60oC with reaction time variation were 1,2,3,4,5, and 6 hours. Reaction products were analyzed by TLC, UV-Vis spectrophotometer, and GC-MS. The XRD characterization results showed typical peak of H3PMo12O40 at 26o with a very high intensity. Acidity test analysis showed the Bronsted acid site moles number of 0.3340 mmol/g, while the Lewis acid site moles number of 7.45 x 10-3 mmol/g. From the results test of TLC and UV-Vis spectrophotometer, the H3PMo12O40/bentonit catalytic activity began to look at anethole transformation since the first one hour, the optimum reaction time of 3 hours with %anethole conversion of 61.54%, and was obtained anethole’s λmaks at 258.5 nm and product’s λmaks of 207 nm. From the analysis by GC-MS, was obtained the product molekol weight of 208 g/mole and 210 g/mole.
