Process for the production of acetic acid from methanol and carbon monoxide using supported rhodium catalyst. |
摘要 |
<p>A liquid feed containing methanol, carbon monoxide, an alkyl iodide and a solvent is contacted with a supported rhodium catalyst to produce acetic acid at a temperature of 140-250 DEG C and a pressure of 15-60 kg/cm<2>G with a partial pressure of carbon monoxide of 7-30 kg/cm<2> while maintaining (a) the water concentration of the product solution in the range of 0.5-10 % by weight and (b) the carbonylation degree Cr, defined in the specification, of the solution within the reactor at 0.15 or more. The solvent may be a carboxylic acid or a carboxylic acid ester.</p> |
