Method for producing propylene oxide

A method for producing propylene oxide, in which the method comprises: producing propylene oxide by supplying a liquid containing a peroxide and propylene to a fixed bed reactor filled with a catalyst; stopping the supply of the peroxide-containing liquid; bringing a liquefied gas into contact with a catalyst in the fixed bed reactor after the stopping of the supply of the liquid containing the peroxide; and supplying an inert gas to the fixed bed reactor. 一种方法，其为制造环氧丙烷的方法，其中，所述方法包含：向填充有催化剂的固定床反应器供给包含过氧化物的液体和丙烯，从而制造环氧丙烷；停止包含过氧化物的液体的所述供给；在包含过氧化物的液体供给的所述停止之后，使液化气体在所述固定床反应器内与催化剂接触；和向所述固定床反应器供给非活性气体。
