Abstract

The invention relates to an integrated process for the preparation of epoxidised olefins. In the first stage, dilute hydrogen peroxide solutions are prepared from the elements hydrogen and oxygen and are reacted in a subsequent liquid-phase epoxidation with olefin in the presence of titanium silicalite to form epoxidised olefins, and the solvents are returned to the H2O2 process again.
