| titleOfInvention | Backpack reaction rectification equipment for synthesizing diethyl oxalate and process thereof |
| abstract | The invention relates to backpack reaction rectification equipment for synthesizing diethyl oxalate and a process thereof, wherein the equipment comprises a raw material preheater, a pre-reactor, a reaction rectification tower, a first backpack reactor, a second backpack reactor and an ethanol recovery tower which are connected with each other through pipelines; dimethyl oxalate and ethanol raw materials react through a pre-reactor and a two-stage knapsack reactor, and then a diethyl oxalate product with the quality purity higher than 99 percent is obtained under the action of a reaction rectifying tower; on the other hand, the mixture of ethanol and methanol extracted from the top of the reaction rectifying tower is sent to an ethanol recovery tower to obtain high-quality methanol and recyclable ethanol. The backpack reaction rectification process for synthesizing diethyl oxalate has the advantages of high reaction conversion rate, high selectivity, low energy consumption, high raw material utilization rate and the like. |
