ISOMERIZATION OF n-PENTANE CATALYZED BY IONIC LIQUIDS [BMIM] Cl-AlCl3

Abstract

Abstract: In order to study the catalytic isomerization performance of ionic liquid, the acidity of synthesized ionic liquid [BMIM]Cl-AlCl3 were characterized by acetonitrile adsorption FT-IR spectra and UV-vis spectra. The effects of AlCl3 mole fraction, types and amount of initiator, reaction temperature and catalyst/oil mass ratio on pentane isomerization were also investigated. The results show that the acidities of ionic liquids are enhanced with the increase of AlCl3 mole fraction. When the AlCl3 mole fraction and 1-chlorobutane volume fraction is 0.70 and 8%, respectively, the conversion of n-pentane and yield of isoparaffin can reach to 88.1% and 74.8%, respectively at the conditions of 120℃ and catalyst/oil mass ratio of 1:1.
