Raw material stirring device with temperature detection function for preparing solid sodium methoxide

Abstract

The raw material stirring device comprises a tank body, a vacuum pump and a heater, a feeding pipe A is installed in the middle of one side of the top end of the tank body, and a feeding pipe B is installed in the middle of the side, away from the feeding pipe A, of the top end of the tank body; the heater is mounted at the top end of one side of the feeding pipe A on the outer surface of the tankbody through a hot air pipe, a vacuum pump is mounted at the lower end of the hot air pipe on the outer surface of the tank body through a vacuum pipe, and a nitrogen inlet pipe is mounted on one side, deviating from the vacuum pipe, close to the top end; a controller is mounted at the lower end of the nitrogen inlet pipe on one side of the tank body through a connecting rod. According to the invention, the problems of fewer temperature detection modules, easiness in causing safety accidents after the detection modules are damaged, simpler stirring structure, poor stirring uniformity and lowdissolving efficiency of the existing device are solved, and the use convenience of the device is improved.

Description

technical field [0001] The invention relates to the technical field of solid sodium methoxide preparation, in particular to a raw material stirring device with temperature detection for the preparation of solid sodium methoxide. Background technique [0002] Sodium methoxide, hazardous chemical, corrosive and spontaneously combustible. It is mainly used in the pharmaceutical industry, as a condensation agent, chemical reagent, and catalyst for edible oil treatment in organic synthesis. Sodium methoxide has a wide range of uses, mainly used in the production of sulfa drugs, sodium methoxide is also a catalyst for organic synthesis, used in pesticide production and oil processing industry, its production process is generally prepared by solid sodium hydroxide and methanol in a certain proportion , after stirring and dissolving, after precipitation and clarification, solid impurities are removed, the clear liquid is pumped into the top of the reaction dehydration tower, and re...
