| 发明名称 | Production of acetic acid with high conversion rate | ||
| 摘要 | A process for producing acetic acid comprising the steps of reacting carbon monoxide and at least one of methanol and a methanol derivative in a first reactor under conditions effective to produce a crude acetic acid product; separating the crude acetic acid product into at least one derivative stream, at least one of the at least one derivative stream comprising residual carbon monoxide; and reacting at least a portion of the residual carbon monoxide with at least one of methanol and a methanol derivative over a metal catalyst in a second reactor to produce additional acetic acid. | ||

| 主权项 | 1. A process for producing acetic acid, comprising: contacting at least one of a carbonylation reaction stream and a derivative thereof comprising from 25 mol % to 75 mol % carbon monoxide with at least one of methanol and a methanol derivative over a metal catalyst to produce an acetic acid composition. | ||
