Process for Acetic Acid Preparation Using Rhodium and Inorganic Iodide Catalyst Systems |
| abstract |
Process for substantially reducing the formation of carbonyl impurities by known methods of methanol carbonylation. The formation of carbonyl impurities, especially acetaldehyde, crotonaldehyde and 2-ethylcrotonaldehyde, by methanol carbonylation reactions is reduced by keeping the hydrogen partial pressure between 0.69 and 27.6 kPa (a) at a total reaction pressure of 15 to 40 atmospheres. |
