Abstract:
1. A carbonylation process for producing a carbonylation product having a low aromatic content, the process comprising: contacting a reactant composition that comprises (i) a reactant selected from the group consisting of methanol, methyl acetate, methyl formate, dimethyl ether, and mixtures thereof and (ii) an aromatic compound, with a guard bed that comprises an adsorbent to form a de-aromatic reactant composition; reacting carbon monoxide with the de-aromatic reactant composition in a reactor containing a reaction medium to produce a reaction solution comprising acetic acid, and wherein the reaction medium comprises water, acetic acid, methyl acetate, methyl iodide, and a catalyst; and withdrawing a reaction solution from the reactor, wherein the reaction solution comprises less than 40 wppm aromatic compounds, based on the total weight of the reaction solution.
