Effective and Fast Epoxidation Reaction of Linseed Oil Using 50 wt% Hydrogen Peroxyde

摘要: Epoxidation of linseed oil was performed with peracetic acid formed in situ by the reaction ofhydrogen peroxide and acetic presence Amberlite 120H as catalyst, toluene solvent. Some variables were evaluated temperature molar ratio solution aqueous hydrogen (30 50 wt%) for obtaining a maximum yield conversion epoxidized oil. The characterization double bonds (DB) to epoxy ring, relative percentage epoxidation selectivity, 1H-NMR FTIR-HART. conditions rendered 93.4%, or 97% selectivity 96.3% obtained at 80°C, employing 1:1.5 H2O2 (50 wt%), 1:0.5 DB acid, 25 wt% only min good reproducibility (±1.1%).
