Abstract: This invention relates to a process for the epoxidation of a tetrasubstituted alkene such as terpinolene to the corresponding epoxide such as terpinolene epoxide by reacting the tetrasubstituted alkene with peracetic acid prepared in situ from acetic anhydride and hydrogen peroxide in the presence of at least one buffering agent. Further, the invention relates to the use of an oxidizing agent comprising hydrogen peroxide and acetic anhydride for the in-situ epoxidation of a tetrasubstituted alkene.
