The utility model discloses an electronic-grade chemical reaction kettle with a feeding device. The electronic-grade chemical reaction kettle comprises a kettle body which is internally provided with a stirring device, wherein a material inlet in the kettle body is connected with the feeding device; the feeding device comprises a raw material storage tank which is provided with a nitrogen inlet and a material outlet; a nitrogen pressure pipeline is arranged at the nitrogen inlet and is provided with a pressure reducing valve; the raw material storage tank is internally provided with a pressure sensor; a pressure signal of the pressure sensor is led out of the raw material storage tank through a lead and is connected to the signal input end of a controller; the signal output end of the controller is connected with the pressure reducing valve in a controlling manner; a material outlet pipe is arranged at the material outlet of the raw material storage tank; a regulating valve and a mass flow meter are arranged on the material outlet pipe; and the other end of the material outlet pipe is connected to the material inlet in the kettle body. By increasing the nitrogen pressure at the top end of the raw material storage tank and controlling the materials to enter the reaction kettle in cooperation with a mass flow meter, the electronic-grade chemical reaction kettle not only can greatly reduce the investment cost, but also always keep the feeding at a stable state.
