Claims (4)

1. Способ проведения каталитической жидкофазной экзотермической реакции олефина С35 с гидроперекисью алкиларила, включающий пропускание смеси, содержащей олефин и гидроперекись, при условиях повышенной температуры и давления реакции, через ряд отдельных реакционных зон, каждая из которых содержит слой твердого катализатора эпоксидирования, удаление жидкой реакционной смеси из последней из упомянутых отдельных реакционных зон, редуцирование давления для обеспечения частичного испарения и понижения температуры реакционной смеси, удаленной из последней из отдельных реакционных зон, нагрев частично испаренной смеси путем косвенного теплообмена с реакционной смесью из первой или промежуточной реакционной зоны и нагрев исходной смеси, содержащей олефин и гидроперекись, путем косвенного теплообмена с реакционной смесью из первой или промежуточной реакционной зоны.1.

The method according to claim 1, in which the propylene is reacted with ethylbenzene hydroperoxide to form propylene oxide. 3. Способ по п.1, в котором частично испаренную смесь нагревают путем косвенного теплообмена с реакционной смесью из предпоследней реакционной зоны. 3. The method according to claim 1, in which the partially evaporated mixture is heated by indirect heat exchange with the reaction mixture from the penultimate reaction zone. 4. Реакционная система для проведения экзотермической реакции олефина с органической гидроперекисью с образованием оксиранового соединения, содержащая реактор, имеющий ряд отдельных зон, содержащих слои твердого катализатора эпоксидирования, устройства для отвода тепла экзотермической реакции путем косвенного теплообмена из реакционной жидкости их каждой отдельной зоны, кроме последней в ряде, устройства для редуцирования давления и частичного испарения реакционной смеси из последней отдельной зоны и устройства для нагрева путем косвенного теплообмена холодного потока на входе в реактор, а также частично испаренной смеси из последней отдельной зоны путем косвенного теплообмена с реакционной смесью из каждой отдельной зоны, кроме последней в ряду. 4. A reaction system for conducting an exothermic reaction of an olefin with organic hydroperoxide to form an oxirane compound, containing a reactor having a number of separate zones containing layers of a solid epoxidation catalyst, devices for removing heat of an exothermic reaction by indirect heat exchange from the reaction liquid of each individual zone, except the last in a number, devices for reducing pressure and partial evaporation of the reaction mixture from the last separate zone and a device for heating by consecrated heat exchange of a cold stream at the inlet to the reactor, as well as partially evaporated mixture from the last separate zone by indirect heat exchange with the reaction mixture from each separate zone, except the last in a row.
