Abstract

The invention discloses distillation equipment for synthesizing acid salicylic acid and a distillation method of the distillation equipment. The distillation equipment comprises a base, a distillation shell, a mounting shell, a distillation mechanism and a cooling mechanism, wherein the top side surface of the base is fixedly connected with a distillation shell, the top side of the distillation shell is provided with a mounting shell, and the side surface of the mounting shell is fixedly communicated with a feeding pipe; the distillation mechanism comprises a servo motor, a stirring shaft, a stirring rod and a heating plate, the servo motor is fixedly connected to the surface of the top side of the mounting shell, the output end of the servo motor is connected with the stirring shaft, the stirring rod is fixedly connected to the side surface of the stirring shaft, the heating plate is placed in the distillation shell, and a baffle plate is fixedly connected to the inner wall of the distillation shell. And through holes are formed in the side surfaces of the baffle plates. According to the distillation equipment for synthesizing the acid-based salicylic acid and the distillation method of the distillation equipment, the design is novel, the structure is simple, heating distillation can be conveniently carried out on acid-based salicylic acid liquid, liquid in the distillation shell can be conveniently stirred, and the distillation effect is improved.

Description

technical field [0001] The application relates to the technical field of distillation equipment, in particular to a distillation equipment for synthesis of acid-based salicylic acid and a distillation method thereof. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. The combination of unit operations; compared with other separation methods, such as extraction, filtration and crystallization, etc., its advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities will be introduced. [0003] At present, there are many problems in the use of distillation equipment. The distillation effect of acid-based salicylic acid synthesis in ...
