Abstract
The present invention relates to a process for the liquid phase epoxidation of a normally liquid olefinic compound to corresponding organic epoxide compound using aqueous or anhydrous organic hydroperoxide as an oxidizing agent in the presence of a supported nano-gold catalysts at the effective organic hydroperoxide/olefinic compound mole ratio, catalyst/olefinic compound weight ratio and temperature to yield the epoxide.
