Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessels, specifically a reaction vessel for the synthesis of caprylic / capric glyceride. Background Technology
[0002] The basic steps for synthesizing caprylic / capric glyceride inside a reaction vessel are as follows:
[0003] First, prepare the main raw materials such as octanoic acid, capric acid, and glycerol. Octanoic acid and capric acid are usually liquid organic acids, while glycerol is a triol. Ensure that the purity of the raw materials meets the synthesis requirements and weigh them according to a certain molar ratio. Generally, the ratio of the total molar amount of octanoic acid and capric acid to the molar amount of glycerol is close to 3:1, which is the ideal ratio for synthesizing triesters. Clean and dry the reaction vessel to ensure that there are no impurities or moisture inside the reaction vessel.
[0004] Add the weighed glycerol to the reaction vessel, and then slowly add octanoic acid and capric acid. The materials can be added through the feed port at the top of the reaction vessel, and the stirring device should be turned on during the feeding process to ensure that the raw materials are initially mixed evenly. The stirring speed is generally controlled at about 100-300 rpm to avoid splashing of raw materials.
[0005] To accelerate the esterification reaction, a suitable catalyst needs to be added; commonly used catalysts include acidic catalysts such as p-toluenesulfonic acid.
[0006] Heating the reactor and controlling the reaction temperature at approximately 180-220℃ is crucial for successful esterification. Stirring must be maintained throughout the reaction to ensure thorough contact between the reactants. Simultaneously, the reflux device in the reactor continuously separates the water generated during the reaction, promoting the reaction towards ester formation. Reduced pressure distillation can be used to lower the pressure of the reaction system, facilitating water evaporation. The reaction time is generally around 4-8 hours, but the exact time can be determined by monitoring the reaction progress.
[0007] After the reaction is complete, stop heating and stirring; allow the reaction product to cool to room temperature in the reaction vessel; transfer the reaction product to a separation device and remove the catalyst and other solid impurities by filtration or other methods; if the product is dark in color, it can be treated by activated carbon decolorization or other methods to obtain a colorless or pale yellow caprylic / capric glyceride product.
[0008] After the synthesis of caprylic / capric glyceride is completed inside the reactor, it needs to be cooled to room temperature. If the cooling rate is too slow, it will prolong the entire production cycle. In industrial production, time is cost, and a long cooling process will reduce the turnover rate of equipment.

[0026] Please see Figure 1-5This utility model provides a reactor for the synthesis of caprylic / capric glycerol ester, including a reactor body 1. A reducer 2 is fixedly installed on the top of the reactor body 1, and a stirring blade 3 is installed on the lower side of the interior of the reactor body 1. The stirring shaft of the stirring blade 3 is fixedly connected to the output shaft of the reducer 2 through a coupling. A rapid cooling component mounting plate 4 is fixedly installed on the upper side of the interior of the reactor body 1. A cooling coil 44 is installed at the bottom of the rapid cooling component mounting plate 4. An inlet pipe 42 is fixedly installed at one end of the cooling coil 44, and an outlet pipe 41 is fixedly installed at the other end of the cooling coil 44. A medium discharge pipe 43 is fixedly provided at the end of the outlet pipe 41 away from the cooling coil 44, and a medium inlet pipe 431 is fixedly provided at the end of the inlet pipe 42 away from the cooling coil 44. The medium inlet pipe 431 and the medium discharge pipe 43 are sealed and inserted into the side wall of the reactor body 1.
[0027] Working Principle: After the synthesis of caprylic / capric glyceride is completed inside the reactor, it needs to be cooled to room temperature. When cooling is required, a cooling medium enters the medium inlet pipe 431. The cooling medium includes, but is not limited to, cooling water and liquid nitrogen. At this time, the medium inlet pipe 431 enters the cooling coil 44 through the inlet pipe 42. The cooling coil 44 is set in four sets and connected end to end. At the same time, the four sets of cooling coils 44 are submerged in the material, which increases the cooling effect between the cooling medium and the high-temperature material. The cooling water inside the cooling coil 44 can cool the material inside the reactor, increasing the cooling effect. This reduces speed, shortens the overall production cycle, and increases equipment turnover. When cooling medium is introduced into the four sets of cooling coils 44, to ensure stability and prevent shaking during operation, upper limit plates 45 and lower limit plates 47 are installed on the outer sides of each coil. The lower limit plates 47 and upper limit plates 45 are fixed together by four sets of stabilizing seats 46. Additionally, positioning seats 471, evenly installed on the outer circumference of the lower limit plate 47, each have a positioning post 472 inserted inside. This method ensures the stability of the four sets of cooling coils 44 during operation.
[0028] The spiral cooling coil 44 has a large contact area with the material; the cooling coil 44 is coiled inside the reactor, which can provide more surface area for material contact in a limited space compared to other simple-shaped cooling devices; the structure of the cooling coil 44 allows the cooling medium to form a more complex flow path inside the coil; the flow pattern can ensure that the cooling medium is in full contact with the coil wall and absorbs heat better; the heat in the material can be quickly transferred from the material to the surface of the cooling coil 44 and then carried away by the cooling medium, thereby achieving efficient cooling.
[0029] As a preferred embodiment, the rapid cooling component mounting plate 4 is a circular structure made of metal, and four sets of cooling coils 44 are evenly installed on the bottom of the rapid cooling component mounting plate 4. At the same time, the four sets of cooling coils 44 are all spiral structures made of copper.
[0030] The four sets of cooling coils 44 have the same pitch and number of threads, and the bottoms of the four sets of cooling coils 44 are connected by a connecting pipe 48. At the same time, the four sets of cooling coils 44 are connected end to end.
[0031] In a preferred embodiment, an upper limit plate 45 is installed on the upper outer side of the four sets of cooling coils 44, and a lower limit plate 47 is installed on the lower outer side of the four sets of cooling coils 44. Both the lower limit plate 47 and the upper limit plate 45 are arranged in a ring shape, and the diameters of the lower limit plate 47 and the upper limit plate 45 are the same.
[0032] The lower limit plate 47 and the upper limit plate 45 are evenly provided with four sets of arc-shaped slots, and the lower limit plate 47 and the upper limit plate 45 are evenly fixedly connected by four sets of parallel stabilizers 46.
[0033] In a preferred embodiment, three sets of positioning seats 471 are evenly installed on the outer circumference of the lower limit piece 47, and the positioning seats 471 are provided with positioning holes that are adapted to the size of the positioning posts 472, while the positioning posts 472 are inserted into the positioning holes.
[0034] A fixing seat 473 is welded and fixed to the bottom of the positioning column 472. An "L"-shaped connecting frame is fixedly installed at the end of the fixing seat 473, and the end of the "L"-shaped connecting frame is fixedly installed on the inner wall of the reactor body 1.
