PROCESS OF PRODUCING OXALATE BY CO GAS PHASE METHOD |
摘要 |
A process of producing oxalate by CO gas phase method includes the following steps: a) introducing nitrite salt, water and an inorganic acid first into a reactor I to produce a NO containing effluent I; and separating the resultant effluent to obtain the effluent II of NO; b) introducing the effluent II of NO, a C1-C4 alkanol and oxygen into a reactor II to be subjected to the reaction, and separating the resultant effluent to obtain the effluent IV of C1-C4 alkyl nitrites; c) introducing the effluent IV of C1-C4 alkyl nitrites and a CO gas stream into a coupling reactor where they are reacted to produce a NO containing effluent VI. The reactor I and/or the reactor II are preferably rotating supergravity reactors. Therefore, the process is applicable to the industrial production of oxalate by CO gas phase method. |
