Abstract
Continuous processes comprising: oxidizing a ketone with a solution comprising active oxygen in a reactor in the presence of a buffer substance and a stripping gas to form a gas stream comprising a dioxirane and a liquid stream; and continuously drawing the gas stream comprising the dioxirane and the liquid stream from the reactor; wherein a liquid phase residence time of 1 minute to 4 hours and a normalized condensate mass flow rate of at least 500 g/mol of active oxygen are maintained.
