Yield:134-20-3 96.8%

Reaction Conditions:

with sodium hypochlorite;sodium hydroxide in methanol;water at 0 - 80; for 0.0583333 h;Temperature;

Steps:

1.1; 2.1; 3.1; 1; 4.1; 5.1; 6.1; 2.1; 7.1; 8.1; 9.1; 3.1; 4.1 Example 5: (Only the reaction temperature is different, other parameters are the same as Example 4)

(1) Phthalimide, water, sodium hydroxide and methanol are prepared into a phthalimide solution in a mass ratio of 1:1.12:0.28:1.006. The phthalimide solution and the sodium hypochlorite solution were pumped into the micro-channel reactor at a flow rate of 15.50 ml/min and 24.03 ml/min through a metering pump, respectively. The reaction temperature was 0° C. and the reaction solution retention time was 30 s. Reactor and pipeline react in series; at the same time preheat the water, turn on the water pump, the flow rate is 24.03ml/min, the reaction liquid and the preheated water are mixed into the pipeline after micro-mixer to react, the reaction temperature is 80 , the reaction liquid remains At a time of 180s, the reaction solution flows out and is continuously centrifuged in an annular gap to obtain a solution of methyl anthranilate for use. The effluent from different batches was sampled and the purity was determined to be greater than 99.2% by liquid chromatography, and the yield was not less than 96.8%.
