[0002] In high-temperature chemical reactions, easily sublimable solid reactants (such as metal carbonyl compounds and elemental iodine) often condense and deposit on the inner wall of the condenser due to excessively high vapor pressure. Traditional reflux devices cannot effectively recover the condensate, leading to problems such as low raw material utilization, decreased reaction yield, and waste of high-value raw materials.

[0003] Therefore, how to improve the utilization rate of easily sublimable substances in high-temperature reactions is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0026] See Figure 1 This application provides a reaction apparatus suitable for easily sublimable reactants, including a reaction vessel 100, a first condenser 200, and a material removal component 500. The first condenser 200 is vertically disposed above the reaction vessel 100, and its first end is connected to the top of the reaction vessel 100. The material removal component 500 is disposed inside the first condenser 200 and can move along the inner wall of the first condenser 200 to scrape off the raw materials adhering to the inner wall of the first condenser 200.

[0027] Specifically, the first condenser 200 is vertically positioned above the reactor 100 and close to the top of the reactor 100 to ensure that high-temperature steam (140-180℃) enters the condensation area via the shortest path, thereby preventing premature sublimation of the steam during transport.

[0028] During use, as the reaction proceeds, easily sublimable solid reactants are deposited on the inner wall of the first condenser 200. The operator activates the material removal component 500 to act on the first condenser 200, applying force to the inner wall of the first condenser 200 to remove the reactants adhering to the inner wall of the first condenser 200. This allows the reactants adhering to the inner wall of the first condenser 200 to fall back into the reactor 100 to continue participating in the reaction, thereby improving the utilization rate of easily sublimable substances in high-temperature reactions.

[0029] To optimize the above technical solution, the reaction apparatus suitable for easily sublimated reactants also includes a connecting pipe 300 and a second condenser 400. The two ends of the connecting pipe 300 are respectively connected to the second end of the first condenser 200 and the inlet of the second condenser 400. The second condenser 400 is used to condense steam.

[0030] Specifically, during the reaction process, the steam generated inside the reactor 100 enters the first condenser 200. The steam that is not condensed by the first condenser 200 enters the second condenser 400 through the connecting pipe 300. The remaining steam is condensed into liquid inside the second condenser 400 and flows back to the first condenser 200 through the connecting pipe 300, thereby serving to flush the inner wall of the first condenser 200.

[0031] The reaction apparatus suitable for easily sublimable reactants has a two-stage condensation function: the first condenser 200 is the main sublimation zone, and the second condenser 400 is used for deep condensation to capture residual vapor.

[0032] In use, the easily sublimable solid reactant is deposited on the inner wall of the first condenser 200. The material removal component 500 is activated and moves against the inner wall of the first condenser 200 to scrape off the raw material adhering to the inner wall of the first condenser 200. The second condenser 400 is activated to condense the excess vapor generated in the reactor 100 into liquid, which flows into the first condenser 200 and washes away the raw material adhering to the inner wall of the first condenser 200, thereby improving the utilization rate of the easily sublimable substance in the high-temperature reaction.

[0033] It should be noted that, under normal circumstances, the first condenser 200 can complete the condensation of steam independently by adjusting the temperature of the first condenser 200. However, this application achieves further steam transport and condensation by setting up a connecting pipe 300 and a second condenser 400. During the transport process, the temperature of the steam will be reduced so that the second condenser 400 can further condense the steam. The temperatures of the first condenser 200 and the second condenser 400 can be the same or different.

[0034] Specifically, the set temperature of the second condenser 400 is lower than that of the first condenser 200 in order to improve the condensation efficiency of the second condenser 400, thereby improving the utilization rate of raw materials for easily sublimable substances in high-temperature reactions.

[0035] To optimize the above technical solution, the connecting pipe 300 is an inclined pipe, and in the vertical direction, the height of the inlet of the second condenser 400 is higher than the height of the first end of the first condenser 200.

[0036] Specifically, it is preferable that the connecting pipe 300 forms an angle of 15-25° with the horizontal plane, so that the liquid in the second condenser 400 can flow into the first condenser 200 by adhering to the connecting pipe 300, adhering to the inner wall of the first condenser 200, and flushing the inner wall of the first condenser 200, thereby playing an auxiliary role in removing sublimation products.

[0037] It should be noted that the material removal component 500 can have multiple designs, as long as it can act on the inner wall of the first condenser 200. Its action mode can be scraping or vibration. The following are three embodiments of the material removal component 500.

[0038] In some embodiments, the material removal assembly 500 includes a first motor, a rotating shaft, and a first scraper. The motor is connected to the rotating shaft and is used to drive the rotating shaft to rotate. The rotating shaft is axially disposed inside the first condenser 200. The first scraper is spaced apart on the outer wall of the rotating shaft, and the edge of the first scraper is disposed close to the inner wall of the first condenser 200.

[0039] Specifically, the first scraper and the second scraper described below can be made of polytetrafluoroethylene.

[0040] Specifically, the first scraper can be supported by a rod-like structure and installed on the rotating shaft, and there should be an angle between the first scraper and the axis of the rod-like structure to adapt to the inner wall structure of the cylindrical first condenser 200.

[0041] Specifically, a spring may be provided between the first scraper and the rod-shaped structure to abut against the inner wall of the first condenser 200, so as to facilitate the scraping off of the attached material.

[0042] In use, the first motor drives the rotating shaft to rotate, and the rotating shaft drives multiple first scrapers to rotate. The edges of the first scrapers act on the inner wall of the first condenser 200 to scrape off the raw materials adhering to the inner wall of the first condenser 200, thereby improving the utilization rate of raw materials for easily sublimable substances in high-temperature reactions.

[0043] The above solutions are for rotary scraping. Operators can choose the following linear scraping solutions according to their needs.

[0044] In other embodiments, the material removal assembly 500 includes a second motor, a ball screw, a screw nut, and a second scraper. The second motor drives the ball screw to rotate. The ball screw and the screw nut cooperate, and the screw nut moves linearly on the ball screw. The second scraper is fixedly connected to the screw nut and can move axially. The extension direction of the second scraper has an angle with the axial direction, and the edge of the second scraper is located close to the inner wall of the first condenser 200.

[0045] Specifically, the extension direction of the second scraper has an angle of 15-25° with the axial direction.

[0046] Specifically, the linear feed design allows the scraped material to fall off under gravity, while preventing it from re-adhering to the second scraper, thus further improving the utilization rate of easily sublimable substances in high-temperature reactions.

[0047] In use, the second motor drives the ball screw to rotate, and the screw nut moves linearly on the ball screw, which drives the second scraper to move axially. The edge of the second scraper acts on the inner wall of the first condenser 200 to scrape off the raw materials attached to the inner wall of the first condenser 200, thereby improving the utilization rate of easily sublimated substances in high-temperature reactions.

[0048] The above solutions are scraping-type solutions. Operators can choose the following vibration-type solutions according to their needs.

[0049] In other embodiments, the material removal assembly 500 includes an ultrasonic sound-generating element and an actuating element, the actuating element being arranged in contact with the inner wall of the first condenser 200 and being positioned within the range of the ultrasonic waves emitted by the ultrasonic sound-generating element.

[0050] Specifically, the active element can be multiple small thin sheets of metal or piezoelectric material. The ultrasonic waves emitted by the ultrasonic generating element are transmitted to the thin sheets, and the thin sheets vibrate violently at the resonant frequency, thereby shaking off the reactants attached to the inner wall of the reactor 100.

[0051] Specifically, the active element can be a piezoelectric ceramic ring or an array of patches. The ultrasonic waves emitted by the ultrasonic generating element are directly received by the piezoelectric ceramic ring or the array of patches, converted into electrical signals, and then inverted into mechanical vibrations, which act on the inner wall of the reactor 100, thereby shaking off the reactants attached to the inner wall of the reactor 100.

[0052] Specifically, the operator can change the frequency of the ultrasonic waves emitted by the ultrasonic transmitting element according to the needs of use. The ultrasonic waves are received by the acting element and thus act on soft sublimates or hard crystals. When the ultrasonic waves act on hard crystals, the ultrasonic frequency needs to be increased.

[0053] This arrangement enables continuous removal during the reaction process, eliminating the need for motors, shafts, and other mechanical structures, thus protecting the high-precision first condenser 200 and extending its service life.

[0054] To optimize the above technical solution, the reaction apparatus suitable for easily sublimable reactants also includes a tail gas absorption section, which is located at the outlet of the second condenser 400 and is used to absorb the reaction tail gas.

[0055] Specifically, the tail gas absorption section is used to absorb and treat the tail gas generated during the reaction to meet the environmental protection requirements of reaction devices suitable for easily sublimable reactants. The tail gas absorption section may include a Venturi injector, an absorption tower, and an adsorption tank. The operator may set an absorption medium in the absorption tower according to the needs of use, such as sodium hydroxide solution, sodium thiosulfate modified activated carbon, etc.

[0056] To optimize the above technical solution, the first condenser 200 is a straight condenser, and the second condenser 400 is a serpentine condenser.

[0057] Specifically, the serpentine condenser has a water inlet, a water outlet, a steam inlet, and a gas outlet. The "inlet of the second condenser 400" mentioned above refers to the steam inlet, and the "outlet of the second condenser 400" refers to the gas outlet.

[0058] Specifically, the inlet of the serpentine condenser is connected to the water supply component to achieve steam cooling.

[0059] By arranging the serpentine condenser, compared to the linear condenser 400 of the second condenser, the condensation efficiency can be improved, thereby increasing the utilization rate of raw materials for easily sublimable substances in high-temperature reactions.

[0060] To optimize the above technical solution, the reaction apparatus suitable for easily sublimated reactants further includes a driving component, a connecting rod, and a stirring blade 600. The driving component is located at the top of the first condenser 200 and is connected to the first end of the connecting rod. The connecting rod passes through the first condenser 200 and is located inside the reaction vessel 100. The second end of the connecting rod is connected to the stirring blade 600. The connecting rod is used to drive the stirring blade 600 to rotate.

[0061] To optimize the above technical solution, the reaction apparatus suitable for easily sublimated reactants also includes a heater 700, which is connected to the reaction vessel 100 and used to heat the reaction vessel 100.

[0062] Specifically, heater 700 can control the heating temperature to suit the preparation of different products.

[0063] To optimize the above technical solution, the reaction device suitable for easily sublimated reactants also includes a gas supply component. The reaction vessel 100 also includes an inlet valve and an exhaust valve disposed on the outer wall of the reaction vessel 100. The gas supply component is connected to the inlet valve and is used to introduce inert gas into the interior of the reaction vessel 100.

[0064] In operation, raw materials are placed in the reactor 100, and then the inlet and outlet valves are opened. The gas supply component introduces inert gases such as nitrogen into the reactor 100 through the inlet valve, creating a nitrogen atmosphere in the reactor 100, the first condenser 200, the connecting pipe 300, and the second condenser 400. Then, the heater 700 is turned on, and the reaction begins. The drive component rotates the connecting rod, which in turn rotates the stirring blades 600 to stir the raw materials in the reactor 100. The first condenser 200 is turned on, and at the same time, the material removal component 500 is turned on to scrape the wall, improving the utilization rate of easily sublimable substances in the high-temperature reaction. The second condenser 400 is turned on, and the steam is further condensed into a reaction liquid that flows back to the first condenser 200 and the reactor 100. At the same time, the raw materials adhering to the first condenser 200 are flushed back into the reactor 100, further improving the utilization rate of easily sublimable substances in the high-temperature reaction.

[0065] The raw material, chromium hexacarbonyl, is a white crystalline solid with a boiling point of 220°C. It is stable in air, has a high vapor pressure, and is easily sublimated.

[0066] The current main process for preparing aromatic tricarbonyl chromium complexes involves a high-temperature stirred reaction of hexacarbonyl chromium with an aromatic solvent in a mixed solvent of n-butyl ether and tetrahydrofuran. During the reaction, hexacarbonyl chromium easily sublimates and adheres to the lower end of the condenser, resulting in a low reaction yield. According to existing literature, the current methods and apparatus for preparing aromatic tricarbonyl chromium have yields of only 40%–50%.

[0067] The following are examples of preparing methyl benzoate tricarbonyl chromium using the reaction apparatus provided by this invention, which is suitable for easily sublimable reactants:

[0068] Chromium hexacarbonyl, methyl benzoate, n-butyl ether, and tetrahydrofuran are added to reactor 100. The gas supply is purged with nitrogen to create a nitrogen atmosphere. Heater 700 is turned on for heating, and the drive unit is activated for stirring. The heating temperature is set to 150°C, and the reaction begins. The condensation temperature of the first condenser 200 is set to 10°C, and the wall scraping speed of the first motor is set to 60 r / min. During this process, the chromium hexacarbonyl adhering to the lower end of the first condenser 200 can automatically return to reactor 100 to participate in the reaction. The condensation temperature of the second condenser 400 is -10°C. The reaction liquid flows into the first condenser 200, scouring the inner wall of the first condenser 200 and further scouring the chromium hexacarbonyl adhering to the lower end of the first condenser 200 into reactor 100 to participate in the reaction. The tail gas absorption section is turned on, and the reaction is stopped after 48 hours. The product methyl benzoate tricarbonyl chromium can be obtained after rotary evaporation of the reaction liquid. The above process achieves two-stage recovery of raw materials, with a final product yield of 84.3% and a purity of 99.4%, significantly improving the utilization rate of easily sublimable substances in high-temperature reactions.
