Summary:Described herein is a process for the epoxidation of propene by reacting excess propene with hydrogen peroxide, non-reacted propene is recovered by a series of at least two sequential pressure reduction steps, recompressing the vapors resulting from pressure reduction in these steps in a corresponding series of compression steps in reverse order, and condensing the compressed vapor phase from the first pressure reduction step in a condensing step. В заявке описан способ эпоксидирования пропена по реакции избытка пропена с пероксидом водорода, непрореагировавший пропен извлекают путем проведения серий по меньшей мере двух последовательных стадий понижения давления, повторного сжатия паров, полученных при проводимом на этих стадиях понижении давления, с помощью проводимых в обратном порядке соответствующих серий стадий сжатия и конденсирования сжатой паровой фазы, полученной на первой стадии понижения давления на стадии конденсирования.
