Abstract

The diepoxide of the formula: ##STR1## can be prepared from the corresponding diolefin in a technically simple manner by means of perpropionic acid in a benzene solution. The solution can also be employed in unpurified form with certain maximum contents of 1.5 weight percent of hydrogen peroxide, 1.5 weight percent of water, and of about 800 ppm of mineral acid.
