Description

Technical Field

[0001] The invention relates to the technical field of reaction devices, and in particular to a cyanate synthesis reaction device and method which are convenient for preparing alkali solution. Background Art

[0002] Cyanate esters are a class of organic compounds containing isocyanate groups (–N=C=O). Cyanate esters are important chemical intermediates and are widely used in the synthesis of polymer materials, pharmaceutical chemicals, pesticides, dyes, etc. The most common cyanate esters are isocyanates, which are often used in the production of polyurethane. Alkali needs to be added during the synthesis of cyanate esters. By accurately adjusting the concentration and addition rate of the alkali solution, the main reaction can be selectively promoted (in the synthesis process of cyanate esters, cyanide reacts with alcohol to form cyanate esters. The alkali solution can increase the alkalinity of the reaction system, enhance the nucleophilicity of cyanide, and make it easier to react with alcohols); inhibit the occurrence of side reactions (by adjusting the concentration and addition rate of the alkali solution, the reaction rate can be controlled to avoid excessive reactions, resulting in the formation of by-products or instability during the reaction process), thereby improving the yield and purity of the product.

When the upper liquid outlet nozzle 24 sprays alkali solution from the spray hole 29, the inclination angle of the stirring blade 11 drives the mixed raw materials inside the reaction barrel 1 to turn downward; when the lower liquid outlet nozzle 24 sprays alkali solution from the spray hole 29, the inclination angle of the stirring blade 11 drives the mixed raw materials inside the reaction barrel 1 to turn upward.

[0030] It should be noted that when the present invention is used, the operator lifts the mounting frame 3 by a lifting tool so that the rotating drum 9 is completely exposed from the reaction barrel 1, and then the operator injects the alkali solution required for the cyanate synthesis reaction into the interior of the liquid storage barrel 14 through the liquid adding nozzle 1402, and then seals the inlet of the liquid adding nozzle 1402 through the sealing cap. Before adding the alkali solution, the rotary disk 12 is manually turned so that the arc retaining ring 25 completely seals the two liquid outlet nozzles 24 to prevent the newly added alkali solution from flowing out of the liquid outlet nozzle 24 and the spray hole 29; After adding the alkali solution, the operator adds the raw materials for the cyanate synthesis reaction into the reaction barrel 1, then releases the mounting frame 3 and covers the cover plate 6 on the top of the reaction barrel 1, and starts the driving motor 4 to drive the turntable 12 to rotate, and the turntable 12 drives the multiple rotating drums 9 to move, and the rotating drum 9 rotates by meshing with the annular inner gear 7 through the gear 8, and the rotating drum 9 transmits torque through the limit block 26 and the limit slide 27 to drive the T-shaped drum 10 to rotate, and drives the stirring fan blade 11 to move through the T-shaped drum 10, and the raw materials in the reaction barrel 1 are stirred by the movement of the rotating drum 9, the T-shaped drum 10 and the stirring fan blade 11 to facilitate the mixing of the raw materials; The movement of the plurality of rotating drums 9 drives the sliding rod 19 to move, and the sliding rod 19 drives the arc sliding block 17 to slide along the inner wall of the arc sliding groove provided between the outer surfaces of the outer ring 15 and the inner ring 16, and the movement of the arc sliding block 17 drives the guide column 1701 to slide intermittently into the interior of the groove 1601. At this time, under the action of the spring 1703, the arc sliding block 17 drives the sliding rod 19 to intermittently reciprocate up and down, and the sliding rod 19 drives the T-shaped cylinder 10 to intermittently reciprocate up and down through the U-shaped frame, and the T-shaped cylinder 10 drives the rotating rod 20 to intermittently reciprocate up and down, and the rotating rod 20 intermittently reciprocates forward and reverse through the cooperation of the driving column 21 and the spiral driving groove 28. The rotating rod 20 drives the first bevel gear 22 to rotate forward and reverse through its own forward and reverse rotation, and the first bevel gear 22 drives the stirring blade 11 to intermittently reciprocate 90° through the second bevel gear 23, and the stirring blade 11 intermittently reciprocates 90°; At the same time, the stirring blade 11 is intermittently reciprocating, driving the arc retaining ring 25 to intermittently rotate 90°, and the arc retaining ring 25 drives the two spray holes 29 to be intermittently connected with the upper and lower liquid outlet nozzles 24, and the piston plate 1407 is driven to move up and down through the intermittent up and down reciprocating motion of the slide rod 19, and then through the action of the one-way air inlet valve 1404 and the one-way air outlet valve 1405, the piston plate 1407 compresses the upper cavity and the lower cavity, so that the air inside the upper cavity and the lower cavity alternately enters the interior of the liquid storage barrel 14, so that the pressure inside the liquid storage barrel 14 rises to a fixed value, so that the alkali liquid inside it can be sprayed out from the liquid outlet nozzle 24 later; By adjusting the inclination angle of the stirring blade 11, when the T-shaped cylinder 10 rotates and drives the stirring blade 11 to rotate, the mixed raw materials in the reaction barrel 1 can be turned up and down. When the upper liquid outlet nozzle 24 sprays alkali solution from the spray hole 29, the inclination angle of the stirring blade 11 drives the mixed raw materials in the reaction barrel 1 to turn downward; when the lower liquid outlet nozzle 24 sprays alkali solution from the spray hole 29, the inclination angle of the stirring blade 11 drives the mixed raw materials in the reaction barrel 1 to turn upward. The device can quantitatively and accurately add alkali solution to the cyanate synthesis reaction, and the up and down movement and rotation of the stirring blade 11 can make the newly added alkali solution be turned up and down in time and uniformly, ensuring that the alkali solution can promptly and quickly promote the main reaction and suppress the side reaction, thereby ensuring the reaction efficiency and product purity of the cyanate synthesis reaction; The rotation of the turntable 12 drives the air outlet pipe 18 to move, so that the air outlet hole 13 is connected with the exhaust hole 5 through the air outlet pipe 18. The exhaust hole 5 is connected with the external exhaust pipe to discharge the waste gas generated by the cyanate synthesis reaction into the waste gas treatment device for filtration to avoid the discharge of harmful gases to pollute the environment; after the cyanate synthesis reaction is completed, the synthetic product is discharged from the discharge end of the discharge pipe to the inside of the collecting device by opening the liquid outlet valve 2 for subsequent production process.
