Abstract
Process for the epoxidation of an organic compound containing at least one C-C double bond by means of hydrogen peroxide in the presence of at least one compound which is catalytically active in respect of the epoxidation and methanol, in which water is separated off from a stream A1 leaving the process, comprising methanol and water, and a stream A2 comprising methanol and water resulting from this separation is returned to the process, wherein the stream A2 has a water content in the range of at least 3% by weight, based on the total weight of the stream A2.
