PRODUCTION OF ACETIC ACID

摘要

PURPOSE:To obtain acetic acid in high selectivity and high yield with significant reduction in reaction system corrosion and also in by-product (methane) formation, by using carbon dioxide and methanol as raw materials through a simplified production process. CONSTITUTION:The objective acetic acid can be obtained by catalytic reaction of carbon dioxide with methanol in gasous phase circumstance in the presence of a metallic catalyst (rhodium borne on a carbonaceous carrier), promoter (methyl iodide) and water.
