The present invention relates to a process of producing oxalate by CO gas phase method for chiefly solving the technical problem of the low utilization efficiency of nitrogen oxides or nitrous acid esters in the prior art. The present invention solves the problem in a better way by using the following steps including: a gas phase stream V containing NO and methanol and oxygen enter a supergravity rotating bed reactor II and are subjected to the oxidative esterification reaction to produce an effluent VI containing methyl nitrite; a methyl nitrite effluent VII obtained from separating said effluent VI together with a CO gas II enter a coupling reactor II and is contacted with a catalyst II to react to form a dimethyl oxalate effluent VIII and a gas phase effluent IX containing NO; the resultant dimethyl oxalate effluent VIII is separated to obtain a dimethyl oxalate product I; optionally, the gas phase effluent IX containing NO is returned to the step above so as to be mixed with the gas phase stream V containing NO for being recycled. Therefore, the process is applicable to the industrial production of oxalate by CO gas phase method.
