Abstract
Pada penelitian ini telah dipelajari aplikasi MgF2, Fe2O3 dan Mg1-xFexF2 (x=0,025; 0,050; 0,100 dan 0,150 mol) sebagai katalis dalam reaksi sintesis vitamin E. Katalis dipreparasi dengan metode sol gel kemudian dikarakterisasi dengan XRD dan uji keasaman ditentukan dengan FTIR-piridin dan luas permukaan S(BET) dengan adsorpsi nitrogen. Fe hasil doping memiliki struktur yang sama dengan MgF2 dan juga memiliki sifat keasaman yang sama ditunjukkan dengan adanya sisi asam Lewis dan Bransted. Hasil penelitian menunjukkan bahwa aktivitas tertinggi didapat pada katalis MgF2 yaitu sebesar 98,47% sedang selektivitas tertinggi untuk vitamin E terbesar diperoleh dari katalis Mg0,85Fe0,15F2 yaitu sebesar 79,36%

In this research has studied the application MgF2, Fe2O3 and Mg1-xFexF2 (x = 0.025; 0.050; 0.100 and 0.150 mol) as catalysts in the reaction synthesis of vitamin E. The catalyst prepared by sol gel method and characterized by XRD and acidity test is determined by FTIR-pyridine and the surface area S(BET) with nitrogen adsorption. The result of Fe doped has same structure and acidity with MgF2 that showed by Lewis and Bransted acid site. The results showed that the highest activity obtained in MgF2 catalyst that is equal to 98.47% being the highest selectivity to the largest vitamin E obtained from Mg0,85Fe0,15F2 catalyst that is equal to 79.36%.
