Summary:In a process for continuously epoxidizing propene with hydrogen peroxide and an epoxidation catalyst, a liquid reaction mixture comprising dissolved propene is provided; a sample of this reaction mixture is withdrawn and its weight determined; the sample is depressurized providing a liquid sample and a vapor sample and the weight of one or both of these samples is determined; the content of at least one of hydrogen peroxide, oxygen, propene oxide and propene oxide byproducts is determined in of one or both of the samples; the content of a component in the reaction mixture is calculated from the content of the component in of one or both of the samples, the weight of the samples, and the weight of the sample of the reaction mixture; and a reaction parameter for reacting propene with hydrogen peroxide is adjusted based on the calculated content of a component in the reaction mixture.
