The invention discloses an organic chemical reaction cup which comprises an inner cup, an outer cup and a temperature monitoring device, wherein the inner cup is arranged inside the outer cup; a cup cover is mounted on the outer cup; a liquid guide hopper is arranged at the top end of the cup cover; a spiral circulation cooling square tube is welded inside the outer cup; the water inlet of the circulation cooling square tube is formed above one side of the outer cup; a flow control valve is mounted at the water inlet of the circulation cooling square tube; the temperature monitoring device ismounted on one side of the outer cup. According to the organic chemical reaction cup disclosed by the invention, due to adoption of a double-cup structure and a cup cover on the double-cup structure,the consequence that experiment operators are hurt by fragments and liquid splashing caused by exploded glass cups in sharp reactions can be avoided, meanwhile, cooling water can be circulated throughthe circulation cooling square tube, the flow of the cooling water can be controlled by using the flow control valve, furthermore the velocity and the cooling temperature of a reaction liquid cooledby the cooling water inside the inner cup can be controlled, monitoring can be carried out by using the temperature monitoring device, and the organic chemical reaction cup is good in security and convenient to popularize and use.
