在297 ~ 343 K的条件下，初始溶液温度继续升高，温差变化较为剧

Under the condition of 297 ~ 343 K, the temperature of the initial solution continued to rise, and the temperature difference changed drastically (46 K). The mass transfer rate has less influence on the mass transfer effect than the thermal effect on the mass transfer effect, so the degradation effect is significantly worsened. At 278 to 297K, the opposite is true. It is worth mentioning that it can be seen that in the first 3 minutes, the curve with an initial solution temperature of 278 K reaches the turning point first. It shows that when the initial solution temperature is 278 K, the degradation rate is the fastest. However, the initial solution temperature is the lowest at 278 K, and the corresponding mass transfer rate is the lowest. This is also because at 278 K, the initial solution temperature is the lowest, so during the rising process of the bubble from the capillary, the expansion caused by the heating effect of the bubble is the smallest, so the time for the bubble to escape from the solution is the longest. The quality time is the longest, so the reaction rate is the fastest. This is confirmed by the previous analysis of the influence of gas flow on the degradation of azoxystrobin.

Under conditions from 297 to 343 K, the initial solution temperature continued to rise and the temperature difference changed more dramatically (46 K). The effect of mass transfer rate on mass transfer effect is less than that of heat effect on mass transfer effect, and the degradation effect is significantly worse. At 278-297K, the opposite is true. It is worth mentioning that in the first 3 min, the curve with an initial solution temperature of 278 K is the first to reach a turning point. This indicates that the degradation rate is fastest when the initial solution temperature is 278 K. However, the initial solution temperature of 278 K temperature is the lowest, corresponding to the lowest rate of mass transfer. This is also because 278 K, the lowest temperature of the initial solution, so in the process of the rise of bubbles after leaving the capillary tube, bubbles are the least affected by the heat effect of the expansion, so bubbles from formation to escape solution the longest time, that is, the longest transfer time, so the reaction rate is the fastest. This is confirmed by the analysis of the effect of the previous gas flow on the degradation of the ester.

The temperature of the initial solution continued to rise under the condition of 297 ~ 343K, and the temperature difference was more violent (46 K). The effect of mass transfer rate on mass transfer effect is less than that of heat effect, and the degradation effect is significantly worse. But in 278-297k, it is the opposite. The initial temperature of 278 min is the first turning point. When the initial solution temperature is 278 K, the degradation rate is the fastest. However, the initial solution temperature of 278 K is the lowest and the corresponding mass transfer rate is the lowest. This is also because the initial solution temperature is the lowest at 278k, so in the process of bubble rising after the bubble is separated from the capillary, the bubble has the smallest expansion caused by the heating effect. Therefore, the bubble has the longest time from formation to escaping from the solution, that is, the longest mass transfer time, so the reaction rate is the fastest. This is confirmed by the analysis of the effect of gas flow rate on azoxystrobin degradation.<br>
