PROCESS FOR IMPROVING PRODUCTIVITY OF A CARBONYLATION CATALYST SOLUTION AND IMPROVED CARBONYLATION OF METHANOL

摘要

, Low water-containing reaction medium, rhodium, and corrosion metal contaminants of this invention tartalmazókarbőnilezőkatalizátőr solution to improve the efficiency szőlgálóeljárás during contacting ésvízzel the carbonylation solution ion exchange resin, wherein the katalizátőrőldatvíztartalmát held% range contacting during 0.25 to 50 parts by weight, and then reduced in volume a catalyst solvent containing metal impurities is obtained. The invention further relates to a process for the improved carbonylation of methane to acetic acid, in the removal of which the corroded metal impurities are removed. ŕ
