| titleOfInvention | The preparation method of acetic acid |
| abstract | The present invention prepares acetic acid, inhibits the concentration rising of the hydrogen iodide in carbonylation reactor or the corrosion of generation and carbonylation reactor simultaneously.Described acetic acid comprises: comprising metal catalyst (rhodium catalyst etc.), under the existence of the catalyst system of ionic iodide (lithium iodide etc.) and methyl iodide, make the reactions steps of methyl alcohol and carbon monoxide successive reaction in carbonylation reactor, in the method, i () is all relative to the liquid phase in reactor, metal catalytic agent concentration keeps counting more than 860ppm with weight basis, water concentration remains 0.8 ~ 15 % by weight, methyl iodide concentration remains less than 13.9 % by weight, and methyl acetate concentration remains more than 0.1 % by weight, and/or (ii) is all relative to the liquid phase in reactor, metal catalytic agent concentration keeps counting more than 660ppm with weight basis, water concentration remains 0.8 ~ 3.9 % by weight, ionic iodide concentration remains less than 13 % by weight, methyl iodide concentration remains less than 13.9 % by weight, and methyl acetate concentration remains more than 0.1 % by weight. |
