Abstract

Раскрыто улучшение процесса карбонилирования метанола для получения уксусной кислоты. В частности, раскрыт способ выделения соединений, восстанавливающих перманганат (СВП), из конденсированного потока дистиллята легких фракций, который включает: (а) дистилляцию, по меньшей мере, части конденсированного дистиллята легких фракций для получения потока второго дистиллята, обогащенного СВП; (b) экстракцию потока второго дистиллята водой и выделение из него водного потока, который содержит СВП; и (с) возврат, по меньшей мере, части экстрагированного второго дистиллята ко второму дистиллятору.
