[0024] See also Figure 1-4The utility model provides a synthesis device of 3,5-di-tert-butyl salicylaldehyde, comprising a base 1 and a magnetic stirring rotor device, a rotating card seat 2 is rotatably mounted on the top of the base 1 through a bearing, a card cavity is provided on the top of the rotating card seat 2, a positioning sleeve 3 is installed on the top of the rotating card seat 2 and located outside the card cavity, a reaction glass cup 4 is movably connected inside the positioning sleeve 3, the magnetic stirring rotor device is arranged inside the reaction glass cup 4, a sealing cover 5 is installed on the top of the reaction glass cup 4 through a thread, an installation cavity is provided on the top of the base 1 and located in the middle, and a driving device is arranged inside the installation cavity;

[0025] The driving device includes a small driving motor 6, a power gear ring 7, a vertically mounted magnet block 8, a meshing gear 9 and a transmission gear ring 10. The small driving motor 6 is mounted on the bottom inner wall of the installation cavity, the power gear ring 7 is mounted on the output end of the small driving motor 6, the vertically mounted magnet block 8 is mounted on the inner wall of the power gear ring 7, the meshing gear 9 is mounted on the bottom inner wall of the installation cavity and located on the right side of the power gear ring 7 through the cooperation and rotation of the bearing and the bracket, and the transmission gear ring 10 is mounted on the bottom of the rotating base 2 and located on the outside of the meshing gear 9;

[0026] The magnetic stirring rotor device includes a protective cover 11, a vertical rod 12, a top ball 13, a stirring blade 14, a second positioning sleeve 15 and a horizontal magnet column 16. The second positioning sleeve 15 is installed on the inner wall of the protective cover 11, and the horizontal magnet column 16 is transversely sleeved at the center position of the second positioning sleeve 15. The vertical rod 12 is installed on the upper side of the protective cover 11, the top ball 13 is installed on the top of the vertical rod 12, and the stirring blade 14 is installed on the outer wall of the vertical rod 12.

[0027] Furthermore, the protective cover 11, the vertical rod 12 and the top ball 13 are all made of glass. Glass products are easy to clean and will not react with the experimental solution.

[0028] Furthermore, the stirring blade 14 is spiral-shaped, and the top ball 13 is a hollow sphere. When the stirring blade 14 rotates, the solution in the middle is pushed downward and flows outward to diffuse for stirring. The buoyancy provided by the top ball 13 enables the magnetic stirring rotor device to remain in a vertical state during the stirring process.

[0029] Furthermore, the second positioning sleeve 15 is made of rubber. When the magnetic stirring rotor device is vibrated, the transverse magnet column 16 will pull the second positioning sleeve 15 to deform and displace, thereby buffering the vibration force received, thereby preventing the transverse magnet column 16 from directly exerting force on the glass and causing damage to the glass.

[0030] Furthermore, the angle between the top plane of the rotating holder 2 and the top plane of the base 1 is 15°, so that when the reaction glass 4 is fixed above the rotating holder 2, the reaction glass 4 is in an inclined state, so that when pouring the solution into the reaction glass 4, the solution can be poured against the inclined inner wall of the reaction glass 4 to prevent the poured chemical solution from splashing, making it easy to use and improving the safety of use.

[0031] Furthermore, there are two vertically mounted magnet blocks 8, the magnetic poles of the two vertically mounted magnet blocks 8 are installed in opposite directions, and the length of the horizontal magnet column 16 is smaller than the gap between the two vertically mounted magnet blocks 8. The two ends of the horizontal magnet column 16 are respectively adsorbed and positioned by the two vertically mounted magnet blocks 8, so that the horizontal magnet column 16 is maintained horizontally inside the reaction glass cup 4 and is located between the two vertically mounted magnet blocks 8.

[0032] Embodiment 1: Rotate the sealing cover 5 to open the top of the reaction glass cup 4, and then add nitric acid for the experiment into the reaction glass cup 4. Since the reaction glass cup 4 is tilted, when pouring into the reaction glass cup 4, the raw material will be poured into the inclined inner wall of the reaction glass cup 4 to contact, thereby preventing sputtering. Then, benzaldehyde is added to the nitric acid, and the magnetic stirring rotor device is put into the reaction glass cup 4. The top ball 13 floats on the liquid surface under the action of buoyancy. The top of the reaction glass cup 4 is sealed by the sealing cover 5, and the small drive motor 6 is started. The small drive motor 6 drives the power gear ring 7 to rotate, and the power gear ring 7 drives the vertical magnet block 8 to rotate. When the vertical magnet block 8 revolves, the magnetic adsorption force drives the horizontal magnet column 16 to rotate synchronously. The horizontal magnet column 16 drives the protective cover 11 to rotate through the second positioning sleeve 15, and the protective cover 11 drives the vertical rod 12 and the stirring blade 14 to rotate. When the stirring blade 14 rotates, it pushes the solution in the middle downward and The reaction glass 4 is rotated in an inclined state. The rotation direction of the reaction glass 4 is opposite to that of the magnetic stirring rotor device. The internal solution is accelerated and stirred and mixed by the cooperation of the two. After the mixing is completed, the sealing cover 5 is opened, sulfuric acid is added, and then the top of the reaction glass 4 is sealed by the sealing cover 5 and the stirring is continued. After the reaction is completed, the obtained reaction solution is poured out and added into ice water for filtration to obtain benzaldehyde nitrate.

[0033] Embodiment 2: Add sodium sulfite solution into the reaction glass cup 4, add the obtained benzaldehyde nitrate into the solution, and then continue to stir for reaction, start the small drive motor 6, drive the power gear ring 7 to rotate through the small drive motor 6, the power gear ring 7 drives the vertical magnet block 8 to rotate, and the vertical magnet block 8 drives the horizontal magnet column 16 to rotate synchronously through the magnetic adsorption force when it revolves, and the horizontal magnet column 16 drives the protective cover 11 to rotate through the second positioning sleeve 15, and the protective cover 11 drives the vertical rod 12 and the stirring blade 14 to rotate. When the stirring blade 14 rotates, it pushes the solution near the middle downward and flows outward to diffuse, so that the solution at the top flows to the middle, while the solution near the inner wall of the reaction glass cup 4 flows to the middle. It will flow upward, so that the solution inside the reaction glass cup 4 forms a circulation flow, and the solution will flow between the upper and lower sides, so as to prevent the stratification of solutions of different densities during the stirring process. At the same time, the power gear ring 7 drives the meshing gear 9 to rotate, and the meshing gear 9 drives the rotating card seat 2 to rotate through the transmission gear ring 10. The rotating card seat 2 drives the reaction glass cup 4 to rotate, so that the reaction glass cup 4 rotates in a tilted state. The rotation direction of the reaction glass cup 4 is opposite to the rotation direction of the magnetic stirring rotor device. Through the cooperation of the two, the internal solution is accelerated to be stirred and mixed at the same time. Finally, the obtained solution is poured into ice water for filtration to obtain salicylaldehyde, and its purity is improved by washing with ethanol.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
