Continuous Catalytic Process for Synthesis of Dimethyl Carbonate by Oxidative Carbonylation of Methanol

摘要

invention the oxidative carbonylation reaction of methanol to dimethyl carbonate produced by the device and It relates to a method, and more particularly the dimethyl carbonate production apparatus and method according to the oxidative carbonylation reaction of methanol to dimethyl carbonate to improve the synthesis yield. That is, the present invention improves the conventional reaction systems, but at the same time injecting the methanol, carbon monoxide, oxygen, an inert gas (argon, nitrogen) to a fixed bed gas phase continuous flow reactor, the improvement for changing the material injection line according to the reaction mechanism of dimethyl carbonate through methanol, oxygen, such as by injection to the injection of inert gas and carbon monoxide separately in the reaction vessel, methanol, carbon monoxide, oxygen, an inert gas (argon, nitrogen) at the same time, dimethyl carbonate synthesis reaction as compared to the conventional system for injecting oxidizing carbonate that can improve yield of the methanol carbonylation intended to provide the dimethyl carbonate production apparatus and method of the reaction. ;
