Processes for producing acetic acid and determining corrosion therein are described herein. The processes generally include contacting methanol and carbon monoxide in the presence of a liquid reaction medium under carbonylation conditions sufficient to form acetic acid, wherein the liquid reaction medium ...
Process for the production of acetic acidA process for the production of acetic acid by carbonylating methanol and/or a reactive derivative thereof with carbon monoxide in a carbonylation reactor containing a liquid reaction composition comprising an iridium carbonylation catalyst, methyl iodide co-...
The latest modification, named the Cativa process, was introduced in the 1990s, taking advantage of iridium metal (Kirk-Othmer, 2007). The acetaldehyde process is the second major process for acetic acid production. It is simply based on acetaldehyde oxidation, but the real reaction mechanism ...

Acetic acid is used in numerous industrial chemical preparations and the large-scale productionof acetic acid takes place through several processes. The main method of preparation ismethanol carbonylation. In this process, methanol reacts with carbon monoxide to give aceticacid: CH3OH(l)+ CO(g)→...
. A regular distillation process to dewater acetic acid is known to be energy intensive and to incur high operational costs. Since the separation of acetic acid from water using distillation is far from being the best process, any cost-efficient method to dehydrate acetic acid is in demand. ...
Acetic acid is produced while inhibiting increased concentrations of hydrogen iodide and acetic acid in an acetaldehyde distillation column. A production process of acetic acid comprises a step for allowing methanol to react with carbon monoxide; a step for feeding a flasher with the reaction mixture...
Acetic acid is produced while inhibiting an increased concentration or production of hydrogen iodide in a carbonylation reactor or corrosion of the carbonylation reactor.
