    Abstract: The invention relates to a process for the epoxidation of an olefin comprising (a) reacting the olefin with hydrogen peroxide in the presence of methanol as solvent in at least two reaction stages to obtain a mixture (M-a) comprising olefin oxide, unreacted olefin, methanol and water, wherein between at least two reaction stages, olefin oxide is separated by distillation; (b) separating unreacted olefin from the mixture (M-a) by distillation to obtain a mixture (M-bi) comprising at least 80 wt.-% of olefin and a mixture (M-bii) comprising methanol, water and at least 7 wt.-% of olefin oxide; (c) separating olefin oxide from the mixture (M-bii) in at least one distillation stage to obtain a mixture (M-ci) comprising at least 99 wt.-% of olefin oxide and a mixture (M-cii) comprising water and at least 55 wt.-% of methanol; (d) separating methanol from the mixture (M-cii) in at least one distillation stage to obtain a mixture (M-di) comprising at least 85 wt.-% of methanol and up to 10 wt.-% of water, and a mixture (M-dii) comprising at least 90 wt.-% of water; wherein a vapor top stream (Td) obtained from at least one distillation column used in (d), said vapor top stream (Td) comprising at least 85 wt.-% methanol, is used to operate at least partially at least one vaporizer used in at least one distillation column used in at least one of stages (a), (b) and (c).

    Abstract translation: 本发明涉及烯烃的环氧化方法，其包括（a）在至少两个反应阶段中在甲醇作为溶剂的存在下使烯烃与过氧化氢反应，得到包含烯烃氧化物，未反应的烯烃，甲醇的混合物（Ma） 和水，其中在至少两个反应阶段之间，通过蒸馏分离烯烃氧化物; （b）通过蒸馏从混合物（Ma）中分离未反应的烯烃，得到包含至少80重量％的烯烃和包含甲醇，水和至少7重量％的混合物（M-bii）的混合物（M-bi） .-％的烯烃氧化物; （c）在至少一个蒸馏阶段从所述混合物（M-bii）分离烯烃氧化物以获得包含至少99重量％的烯烃氧化物的混合物（M-ci）和包含水的混合物（M-cii） 和至少55重量％的甲醇; （d）在至少一个蒸馏阶段中从混合物（M-cii）中分离甲醇以获得包含至少85重量％的甲醇和至多10重量％的水的混合物（M-di），以及 包含至少90重量％的水的混合物（M-dii） 其中从（d）中使用的至少一个蒸馏塔获得的蒸汽顶部流（Td），所述蒸气顶部流（Td）包含至少85重量％的甲醇，用于至少部分地使用至少一个使用的蒸发器 在（a），（b）和（c）中的至少一个中使用的至少一个蒸馏塔中。
