Abstract

Раскрыто улучшение способа карбонилирования метанола для получения уксусной кислоты. В частности, раскрыт способ уменьшения образования алкилйодидов и Скарбоновых кислот путем удаления соединений, восстанавливающих перманганат (СВП), из легкой фазы конденсированного потока дистиллята легких фракций, который включает (а) дистилляцию легкой фазы для получения потока дистиллята, обогащенного СВП; и (b) экстракцию третьего потока дистиллята водой в не менее чем два последовательных этапа, и сепарацию из него одного или более водных потоков, которые содержат СВП.
