Efficient hydrolysis reaction kettle for preparing photoinitiator

The utility model relates to the technical field of reaction kettles, and discloses an efficient hydrolysis reaction kettle for preparing a photoinitiator, which comprises a fixed box, a fixed rod is fixedly mounted at the top of one side of the fixed box, a collecting box is fixedly mounted on the outer side of the fixed box, a kettle body is fixedly arranged at the middle position in the fixed box, and cooling liquid is injected into the fixed box. According to the photoinitiator reaction kettle, photoinitiator raw materials broken under high pressure of the kettle body flow into cooling liquid, the water pressure of the cooling liquid rises to push a sealing convex block to move upwards, and at the moment, the cooling liquid flows into a collecting box through a connecting pipe; meanwhile, the sealing convex block can extrude the reset switch to start the alarm, so that people are reminded of timely treatment by making a sound, greater safety accidents are prevented, and meanwhile, the situation that high-
