| titleOfInvention | Method by removing permanganate reducing compound purification of acetic acid logistics |
| abstract | Disclose reduction and/or remove by the method for the permanganate reducing compound (PRC ' S) for making methanol carbonyl in the presence of group VIII metal carbonylating catalyst to produce acetic acid and be formed.More particularly, disclose and PRC ' s or the method for their precursor are reduced and/or removed from the intermediate stream during acetic acid is formed by the carbonylation method.Especially, disclosing wherein makes the low boiling Overhead vapors logistics from light fraction tower undergo the method for being distilled to get overhead, and overhead experience is extracted optionally to remove and/or reduce PRC ' s from this method.This method includes the step of making one or more return logistics from distilation steps and/or extraction steps be recycled to light fraction tower and/or drying tower to improve the control in whole reaction system to water. |
