| titleOfInvention | Low energy carbonylation process |
| abstract | The present invention relates to a low energy production process of acetic acid by carbonylation of methanol. The process of the present invention includes a rhodium-catalysis system performed by using up to two distillation columns under less than about 14% moisture. The process of the present invention preferably controls the product stream to have low levels of propionic acid impurities, and the level of aldehyde impurities is minimized by removing aldehydes or minimizing aldehyde production. The level of iodide is controlled by contacting the product with the ion exchange resin at high temperatures. In a preferred embodiment, the product is purified using one or more silver or mercury ion exchange macroreticular strong acid ion exchange resins. High temperature treatment has the added advantage of controlling the color values (in Pt-Co units) of the product stream. |
