Abstract

In MTO-catalyzed epoxidation, aqueous hydrogen peroxide is typically added dropwise to a dichloromethane solution of the olefin, pyrazole as accelerant, and MTO. The use of sodium percarbonate (SPC) offers a slow release of hydrogen peroxide, that can be accelerated using trifluoroacetic acid.
