Description
A high-efficiency distillation and separation apparatus for the synthesis of side-chain alcohols Technical Field
[0001] This utility model relates to the field of distillation and separation equipment technology, specifically to a high-efficiency distillation and separation equipment for the synthesis of side-chain alcohols. Background Technology
[0002] Side-chain alcohol synthesis refers to the process of attaching specific side-chain groups to alcohol molecules through chemical reactions to generate new compounds or materials. Side-chain alcohols play an important role in organic synthesis and are often used in fields such as drug synthesis and materials science. The synthesis of side-chain alcohols requires separation and processing using distillation equipment.
[0003] For example, the announcement number CN219897088U (named "A Subdivision Distillation Apparatus for the Preparation of Synthetic Leaf Alcohol") includes a support base, a heating base, a distillation kettle, a feed pipe, a steam guiding pipe, a condenser, and a condenser. The heating base is connected to the upper left side of the support base, and the distillation kettle is connected to the top of the heating base. The feed pipe is connected to the upper left side of the distillation kettle, and the steam guiding pipe is connected to the top of the distillation kettle. The condenser is connected to the upper right side of the steam guiding pipe, and the condenser is connected to the lower part of the condenser. The feed pipe is connected to an external conveying device, which transports the raw material to the distillation kettle. The heating base then heats the raw material, and the generated steam enters the condenser through the steam guiding pipe. Under the action of the condenser, the steam condenses into liquid in the condenser and is discharged. The output shaft of the servo motor rotates, which drives the rotating disk to rotate. The rotating disk rotates, which in turn drives the collection bottle to rotate, so that the collection bottle is located below the outlet of the condenser. The collection bottle can be automatically replaced according to the different liquids formed by condensation, improving the convenience of operation.
[0004] The aforementioned distillation apparatus lacks protection against heat-sensitive substances during use, which can lead to the decomposition of these substances required for the synthesis of side-chain alcohols, thus affecting the synthesis efficiency. Therefore, we provide a highly efficient distillation and separation apparatus for the synthesis of side-chain alcohols. Summary of the Invention

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Please refer to Figures 1-4. One embodiment of this utility model is provided: a high-efficiency distillation and separation device for side-chain alcohol synthesis, including a device platform 1.

A vacuum pump 17 is provided at the rear end of the electric heating base 6, and the suction pipe of the vacuum pump 17 is connected to the inside of the distillation tank 8.
[0028] The condenser 14 is located on one side of the distillation tank 8, and the upper and lower ends of the condenser 14 are respectively connected to the sleeve pipe 12 and the drain pipe 16. The top of the top cover 9 is connected to the guide pipe 13, and the guide pipe 13 is movably connected to the sleeve pipe 12.

[0030] In use, the substances required for the synthesis of side-chain alcohols are poured into the interior of the distillation tank 8 for distillation. The top cover 9 is pressed down by the electric push rod 3, sealing the top of the distillation tank 8. Then, the evacuation valve 20 is opened, and the gas inside the distillation tank 8 is extracted by the vacuum pump 17, reducing the pressure inside the distillation tank 8. Then, the switch 5 is pressed, which powers the electric heating element 6 from the power supply box 4. The electric heating element 6 heats the distillation tank 8 for distillation. During the distillation process, the substances required for synthesis are heated in a low-pressure environment, so that the distillation separation of the substances required for synthesis can be achieved without heating to the boiling point of the liquid. This avoids the decomposition of the heat-sensitive substances required for the synthesis of side-chain alcohols due to excessive heating temperature.

Please refer to Figure 1. A sealing plug 10 is fixed to the lower end of the top cover 9 with adhesive. The top cover 9 is connected to the top of the distillation tank 8 by the sealing plug 10. The sealing plug 10, fixed to the lower end of the top cover 9 with adhesive, facilitates the sealing connection between the top cover 9 and the distillation tank 8. Please refer to Figure 1. Support rods 15 are welded to both sides of the outer wall of the condenser 14. Both support rods 15 are welded to the device platform 1. The support rods 15 on both sides of the outer wall of the condenser 14 support and connect the condenser 14 and the device platform 1. Please refer to Figure 1.
