[0024] Example 1:
[0025] Such as figure 1 As shown, a reaction device for producing methyl propionate includes a static mixer, a carbonylation reactor, and a flash evaporator connected in sequence, the top of the flash evaporator is connected to a light removal tower, and the bottom of the flash evaporator is reacted with a catalyst recovery The tail gas from the light removal tower enters the tail gas treatment system after passing through the condenser, and the bottom of the light removal tower is connected to the rectification refining system; the catalyst recovery reactor is connected to the liquid-liquid separation tower through the The upper material separated by the liquid-liquid separation tower enters the tar incineration system, and the obtained heavy phase is returned to the carbonylation reactor. The bottom of the carbonylation reactor is provided with a gas distributor (not shown in the figure).
