FARIAS, Maritana  and  MARTINELLI, Márcia. Epoxidation of soybean oil with [MoO2(acac)2]/TBHP CAtalytic system in [bmim][PF6]. Quím. Nova [online]. 2012, vol.35, n.8, pp.1538-1541. ISSN 0100-4042.

Epoxidation of soybean oil was investigated using 1-n-butyl-3-methylimidazolium hexafluorophosphate [bmim][PF6] ionic liquid as biphasic medium with molybdenum(VI) acetylacetonate complex and tert-butyl hydroperoxide TBHP as oxidizing agent. Reaction conditions were molar ratio TBHP:number of double bonds of oil:catalyst of 100:100:1, reaction temperature of 60 ºC and reaction time between 2 and 24 h. The proposed system showed catalytic activity for epoxidation reactions under tested conditions. Reuse of ionic liquid/catalyst system for epoxidation reactions was also investigated. Evaluation of epoxidation observed in this catalytic system was done by quantitative 1H NMR data.

Keywords : soybean oil; epoxidation; ionic liquids.
