| titleOfInvention | Method of obtaining acetic acid (options) |
| abstract | FIELD: chemistry. n SUBSTANCE: invention pertains to perfection of the method of obtaining acetic acid with rate of volume flow of at least 15g-mol/l/h, a catalytic carbonylation reaction, involving reaction of a compound, chosen from a group containing methanol, methyliodide, methylacetate, dimethyl ether, or their combination, in the presence of carbon monoxide and a catalyst system based on rhodium in a reaction mixture, where the reaction mixture consists of not less than 2.0% mass, water, metal, in concentration of at least 1000 h/million, chosen from a group containing rhodium and a combination of rhodium and iridium, iodide ion in concentration from 2 to 20% weight, and a halogen promoter, chosen from a group, containing halogen-hydrogen, alkyliodide, iodine salt or acetate salt of a group IA metal, group II metal, quatanary ammonium salt, phosphoric acid salt, or their combination in concentration from 2.0% mass to 30.0% mass. The method is used for attaining reaction speed of at least 15 g-mol/l/h. The invention also pertains to the method of obtaining acetic acid from a carbonylation reaction in a system, consisting of a reaction zone and a cleaning zone, and involves the following stages: (a) reaction of methanol, methyliodide, metylacetate, dimethyl ether or their combination with carbon monoxide in the presence of a catalyst system based on rhodium in a reaction mixture, with water content from 0.1% mass to 5.0% mass, iodide ion in concentration from 2 to 20% mass, and a halogen promoter, chosen from a group, containing halogen-hydrogen, alkyliodide, iodine salt or an acetate salt of a group IA metal, group IIA metal, quaternary salt of ammonia, phosphoric acid salt or their combination, in concentration from 2.0% mass to 30.0% mass, and (b) putting a compound, chosen from a group, consisting of methylacetate, dimethyl simple ether, acetic anhydride and their mixture in the reaction zone. n EFFECT: perfection of the method of obtaining acetic acid. n 26 cl, 1 dwg, 4 ex, 1 tbl |
