Abstract

Описан способ дистилляции альдегидной смеси, содержащей альдегид с неразветвленной цепью и альдегид с разветвленной цепью, где способ включает подачу исходного материала, содержащего альдегидную смесь, в резервуар для первого разделения; функционирование указанного резервуара для первого разделения при первой температуре и первом давлении таким образом, что происходит разделение; извлечение первого потока, содержащего альдегид с неразветвленной цепью, из указанного резервуара для первого разделения и подачу указанного первого потока в резервуар для второго разделения; функционирование указанного резервуара для второго разделения при второй температуре и втором давлении таким образом, что происходит разделение; извлечение потока продукта, содержащего альдегид с неразветвленной цепью, и второго потока, содержащего высококипящие компоненты, из указанного резервуара для второго разделения и подачу указанного второго потока в резервуар для третьего разделения; функционирование указанного резервуара для третьего разделения при третьей температуре и третьем давлении таким образом, что происходит разделение; и извлечение третьего потока, содержащего альдегидную смесь, из указанного резервуара для третьего разделения и повторное введение указанного третьего потока в резервуар для первого разделения.
