Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to an integrated synthesis and purification device for nitrile-based resin materials. Background Art

[0002] Nitrile resin is a kind of compound containing phthalonitrile structure and can be cross-linked and polymerized into macromolecular structure. At present, its synthesis method can be divided into four types according to the reaction type: coupling reaction synthesis method, complexation reaction synthesis method, substitution reaction synthesis method and Mannich reaction synthesis method. The coupling reaction synthesis method has harsh reaction conditions, single product, low yield, and is rarely used;

[0003] The complex reaction synthesis method has a complex separation process and a limited number of nitrile resin structures that can be designed, so it is less practical; while the Mannich reaction synthesis method is more used to synthesize thermosetting resins-benzoxazine resins. Therefore, we usually use the substitution reaction synthesis method to synthesize nitrile resins. The substitution reaction synthesis method refers to the use of phenolic compounds and their derivatives with 4-nitrophthalonitrile in a strong polar solvent under the catalysis of a weak base to undergo nucleophilic substitution to finally generate a nitrile resin monomer. The synthesis method has mild reaction conditions, easy control of the synthesis process, and can synthesize nitrile resins of different structures by selecting different phenol sources. It has strong molecular designability and is currently the most important synthesis method for nitrile resins. However, its synthesis and purification process is relatively cumbersome, and the process links are complicated. At present, there is no integrated synthesis device and method for synthesizing and purifying nitrile resins, which brings inconvenience to people's use.

[0004] In order to solve the problems existing in the background technology, the utility model provides an integrated synthesis and purification device for nitrile-based resin materials based on the substitution reaction synthesis method. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an integrated synthesis and purification device for nitrile-based resin materials, comprising a cavity, a cover plate is arranged on the upper surface of the cavity, a servo motor is arranged in the middle of the upper surface of the cover plate, a feed port and a condensation pipe port are arranged on both sides, the output end of the servo motor passes through the cover plate to the inside of the kettle body, a plurality of stirring rods are arranged at the output end of the servo motor, electric heating tubes are arranged on both sides of the lower surface of the cover plate, and heating wires are arranged inside the electric heating tubes;

[0006] Water circulation chambers are provided on both sides of the cavity, and a temperature detector, a water inlet and a water outlet are provided inside the water circulation chamber, and the temperature detector, the water inlet and the water outlet are fixedly connected to the water circulation chamber, and a servo motor is provided in the middle of the upper surface of the cover plate, and the servo motor is connected to a stirring rod that penetrates the reaction chamber;

[0007] When the water in the water circulation chamber of the nitrile-based resin material integrated synthesis and purification device needs to be replaced, it can be replaced through the water inlet and outlet of the water circulation chamber, and the temperature detector can monitor the water temperature inside the chamber in real time. When the chemical material reacts completely inside the reaction chamber and needs to be purified, it can be directly purified inside the reaction chamber. Since the nitrile-based resin is insoluble in water and has a density less than that of water, a water outlet is provided at the bottom of the reaction chamber, and the wastewater is discharged through the water outlet. After multiple purifications and drying, the target nitrile-based resin can be obtained, and the practical performance is relatively high.

[0008] Preferably: a time regulator and a temperature setter are arranged on both sides of the front end outer wall of the cavity; through the above technical scheme, the heating time of the water circulation heating cavity can be set by the time regulator, and the heating temperature of the water circulation heating cavity can be set by the temperature setter.

[0009] Preferably: a transparent observation window is provided in the center of the cavity surface; through the above technical solution, the reaction of the chemical materials inside the reaction chamber can be conveniently observed through the transparent observation window.

[0010] Preferably: a plurality of supporting legs are provided on the underground surface of the cavity; through the above technical solution, the cavity can be supported by the supporting legs.

[0011] Preferably: the water circulation heating chamber is connected to the water outlet, the reaction chamber is connected to the material outlet, and the hydraulic cooler is detachably connected to the water outlet or the material outlet.

[0012] Technical effects and advantages of the utility model:

[0013] The utility model has a reasonable structure and is easy to use. The temperature in the water circulation cavity can be observed in real time through the temperature detector, and the water inside the cavity can be replaced through the water inlet and the water outlet. The mixed solution after the reaction can be directly purified and washed through the water outlet of the reaction chamber. After purification, the reaction sample can be directly dried inside the reaction chamber by heating the water circulation cavity, avoiding the shortcomings of existing equipment. The heating time of the water circulation cavity can also be controlled by the time regulator, and the heating temperature of the water circulation cavity can also be controlled by the temperature setter. The stirring rod connected to the servo motor can fully stir the reaction materials to make the reaction more complete and improve the yield. The device fully considers the convenience of reaction and purification integration, and has high practical performance. BRIEF DESCRIPTION OF THE DRAWINGS
