(57) Abstract: [PROBLEMS] To provide a method for directly producing an oxygenated acetyl compound ethylidene diacetate, acetic acid, acetic anhydride and methyl acetate from synthesis gas via an intermediate compound dimethyl ether. A dimethyl ether is produced from the synthesis gas 13 in the first liquid phase reactor apparatus 201, and an intermediate product stream 25 containing dimethyl ether, methanol and unreacted synthesis gas is fed to the second liquid phase reactor apparatus 301. hand, An oxygenated acetyl compound is synthesized by a catalytic reaction. |
