    • A process for preparing an alkylene oxide comprising contacting an alkyl phenyl hydroperoxide with an alkene in an epoxidation reaction to obtain an alkylene oxide and an alkyl phenyl alcohol, wherein the alkyl phenyl hydroperoxide is prepared by a process comprising reacting an alkyl aryl compound and oxygen to produce a reaction mixture comprising alkyl phenyl hydroperoxide, alkyl aryl compound and oxygen; separating at least a part of the reaction mixture into a product stream comprising alkyl phenyl hydroperoxide and an alkyl aryl compound stream; mixing at least a part of the alkyl aryl compound stream with a basic aqueous solution; separating at least a part of the mixture of alkyl aryl compound and basic aqueous solution with the help of a coalescer to obtain an organic phase containing alkyl aryl compound, and an aqueous phase; and recycling at least a part of the organic phase to the reacting step.
    • 一种制备烯化氧的方法,该方法包括制备烷基苯基氢过氧化物,并使该烷基苯基氢过氧化物与烯烃在环氧化反应中接触以获得烯化氧和烷基苯基醇,其中烷基苯基氢过氧化物通过包括 a)使烷基芳基化合物和氧气反应以制备包含烷基苯基氢过氧化物,烷基芳基化合物和氧气的反应混合物; (b)将至少一部分反应混合物分离成包含烷基苯基氢过氧化物和包含烷基芳基化合物的物流的产物物流; (c)将至少一部分分离的烷基芳基化合物流与碱性水溶液混合; (d)借助聚结器分离至少一部分步骤(c)的混合物以获得含有烷基芳基化合物的分离的有机相和分离的水相; 和(e)将至少一部分含有烷基芳基化合物的分离的有机相再循环至步骤(a)。
