Abstract
Изобретение относится к способу извлечения капролактама из смеси, содержащей капролактам, воду, легкие и тяжелые компоненты, путем проведения первой вакуумной перегонки смеси, приводящей в результате к получению первого кубового продукта, содержащего тяжелые компоненты и капролактам, и первого дистиллятного продукта, содержащего капролактам, воду, ненасыщенные лактамы и легкие компоненты; и проведения, по меньшей мере, для части ненасыщенных лактамов гидрирования.Международная заявка была опубликована вместе с отчетом о международном поиске.
