The epoxidation of D-limonene and b-pinene was successfully carried out using peroxyacetic acid produced in situ in a two-phase dichloromethane and water system, from the commercial reagents tetraacetylethylenediamine (TAED) and sodium peroxycarbonate (PCS) with sodium bicarbonate. The progress of the reaction was evaluated by thin layer chromatography (CCD) and separation by flash column chromatography (CCF), using silica gel 230- 400 mesh. The TAED used in this study was previously purified by recrystallization, with a yield of 80%. The epoxides obtained were analyzed by nuclear magnetic resonance and mass spectrometry and the yields were 72% for D-limonene and 75% for -pinene epoxides.
