Technical Field
[0001] The utility model relates to the technical field of chemical synthesis reactors, in particular to a reactor for chemical drug synthesis. Background Art
[0002] A reactor is an instrument for realizing a reaction process. It is usually capable of realizing a one-way liquid phase reaction process and a multiphase reaction process such as liquid-liquid, gas-liquid, or liquid-solid. A stirring structure is often provided inside the reactor, and a jacket or heat exchange surface is often installed on the outer wall of the reactor, which can exchange heat through an external circulation.

The top of the heat exchange chamber 1 is connected to the water tank 4 through a first medium channel 13. When a heat exchange medium, such as cold water, enters the heat exchange chamber 1 from the first medium channel 13, the heat exchange medium first impacts the inner bottom of the water tank 4 to cause the water tank 4 to react.
