The invention relates to the field of chemical reaction equipment, and particularly relates to a double-layer glass reaction kettle. The double-layer glass reaction kettle comprises a supporting frame and a double-layer glass reaction kettle, a variable-frequency speed-adjustable stirring motor and a motor controller which are mounted on the supporting frame; the variable-frequency speed-adjustable stirring motor is electrically connected with the motor controller; a constant-pressure funnel, a thermometer sleeve, a condensing device and a charging tube are arranged on the double-layer glass reaction kettle; the motor controller is arranged right above the double-layer glass reaction kettle; the output end of the variable-frequency speed-adjustable stirring motor is connected with a stirring rod by a universal joint; the stirring rod is arranged in the double-layer glass reaction kettle. The double-layer glass reaction kettle adopts a double-layer borosilicate glass reaction kettle body and a borosilicate glass reaction kettle cover; the material has excellent physical and chemical properties; moreover, the kettle has a good sealing effect, high stability and high safety; in addition, casters with brakes are arranged on four corners of the lower end part of the supporting frame, so that the entire kettle can be conveniently moved.
