PROCESSES FOR REMOVING AND/OR REDUCING PERMANGANATE REDUCING COMPOUNDS AND ALKYL IODIDES
Continuous acetic acid production with a process to remove and/or reduce permanganate reducing compounds (PRCs), including acetaldehyde. The process involves obtaining a stream comprising the PRCs and removing water from the stream through a dehydrating step, involving distillation, extraction, or p...

| description | Continuous acetic acid production with a process to remove and/or reduce permanganate reducing compounds (PRCs), including acetaldehyde. The process involves obtaining a stream comprising the PRCs and removing water from the stream through a dehydrating step, involving distillation, extraction, or phase separation. After removing water, an alkane may be combined to enhance the separation of PRCs from alkyl iodides.
La présente invention porte sur la production continue d'acide acétique à l'aide d'un procédé afin d'éliminer et/ou de réduire des composés réducteurs de permanganate (PRC), y compris l'acétaldéhyde. Le procédé comprend l'obtention d'un flux comprenant les PRC et l'élimination de l'eau du flux grâce à une étape de déshydratation, impliquant la distillation, l'extraction ou la séparation de phases. Après élimination de l'eau, un alcane peut être combiné pour améliorer la séparation de PRC à partir d'iodures d'alkyle. |
