Experimental device for synthesizing 3, 5-di-tert-butyl-4-hydroxybenzoic acid

The utility model discloses an experimental device for synthesizing 3, 5-di-tert-butyl-4-hydroxybenzoic acid, and relates to the technical field of fine chemical experiments. According to the experimental device for synthesizing the 3, 5-di-tert-butyl-4-hydroxybenzoic acid, the moisture detection device probe and the electric control valve are arranged in the high-pressure ball valve and are connected with the external controller, so that the moisture in a removed solvent is detected in real time, and when the moisture requirement is met, the high-pressure ball valve is automatically closed, so that the 3, 5-di-tert-butyl-4-hydroxybenzoic acid is synthesized. Meanwhile, the high-pressure needle valve is opened through the controller, reaction gas is introduced, the pressure in the kettle is detected in real time through the pressure sensor in the stirring rod, when the pressure requirement is met, the high-pressure needle valve is automatically closed, automatic control is conducted through the system, the pu
