FIG. 1 is a schematic diagram of the present utility model;
in the figure: the device comprises a 1-reaction kettle, a 2-steam regulating valve, a 3-reaction kettle thermometer, a 4-circulating cooling pump, a 5-cooler, a 6-circulating water regulating valve, a 7-cooler thermometer, an 8-elevated tank, a 9-regulating valve, a 10-flowmeter, an L-base material pipe, an L1-liquid outlet pipe and an L2-liquid return pipe.
Detailed Description
In fig. 1, taking the reaction synthesis process for producing fenpyraclonil as an example, the specific operation method is as follows:
