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.
Claims14
A process for the epoxidation of a tetrasubstituted alkene to the corresponding epoxide comprising 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 wherein the hydrogen peroxide is used as an aqueous solution and the reaction is carried out in the presence of at least one inert organic solvent selected from non-halogenated aromatic hydrocarbons, and wherein the tetrasubstituted alkene contains one additional carbon-carbon double bond being trisubstituted.
