Description

A kind of purification method of emamectin salt

Technical field

The present invention relates to the technical field of extracting emamectin salt, specifically a method for purifying emamectin salt.

Background technique

Emamectin salt generally refers to a new type of high-efficiency semi-synthetic antibiotic pesticide synthesized from the fermentation product avermectin B1. It has the characteristics of ultra-high efficiency, low toxicity (the preparation is nearly non-toxic), low residue, and no pollution. Features, widely used in the prevention and control of various pests on vegetables, fruit trees, cotton and other crops.

The existing application number is 201610348559.2. There are the following problems in the implementation of a certain technology:

1. As described in the original text, take 500 ml of mebamectin extract (concentration 700 mg/ml), heat it to 38±2°C, add 75 ml of saturated sodium chloride solution at 15% (V/V), and stir thoroughly for 40 minutes, let it stand for 20 minutes, separate water, and filter. In the filtration step, the method for dealing with impurities on the top of the filter after filtration is generally to open the device after filtration, remove the filter for cleaning. In this patent, there is no treatment after the filtrate is obtained. Impurities must be cleaned. Conventional treatment methods increase the loss of the filter during the entire process. Cleaning or replacing the filter is not only time-consuming and laborious, but also requires disassembly of the filter. This low efficiency affects the entire preparation process.

2. Add the above eluate into a 5000ml three-neck reaction bottle, control the temperature to 60±2°C, distill under reduced pressure, remove the dichloroethane, and obtain the methylaminoavermectin concentrate. During the reduced pressure distillation process, The water vapor condenses into water droplets after cooling, and flows back into the reaction bottle along the steam pipe, making the solubility of the solution inaccurate and affecting the entire preparation process. This problem is not solved in this patent, and a special distiller is generally used. Distillation is carried out, but the distiller is expensive. Preheating after the reaction will still cause water droplets to condense on the mouth of the tube and drip, resulting in inaccurate solubility of the prepared solution. In the subsequent preparation process, it is easy to affect the extraction of emamectin salt and affect the quality of the product. question.

To sum up, in the present invention, the medicinal liquid is first poured into the liquid inlet 203, and the pharmaceutical industry first performs filtration. During the process of filtering through the filter unit 2, the medicinal liquid enters the sealing unit 5 through the sealing tube 501, and then is distilled under reduced pressure. Distillation is carried out. During this process, after multiple filtrations, a large amount of impurities will accumulate on the filter 301. At this time, due to the increase in impurities, they touch the impurity sensor 310. The impurity sensor 310 controls the cleaning motor 305 to start rotating, and then The rotating wheel 307 is rotated, and then the rotating wheel 307 moves inside the cleaning frame 308 to drive the cleaning disc 303 to rise and fall. The cleaning motor 305 cooperates with the lateral sliding plate 304 and the cleaning spring 306 to assist the cleaning motor 305 to move left and right. The plate 303 moves up and down to clean the inside of the filter screen 301, and the impurities enter the recovery bin 312 through the elastic baffle 311 through the opening and closing of the bottom elastic baffle 311.

In the present invention, when the filtrate passes through the sealing tube 501, the sealing fan blade 502 is driven to rotate, which in turn drives the fan blade bevel gear 503 to rotate, which in turn drives the transmission bevel gear 504 and the power bevel gear 505 to rotate, which in turn drives the sealing top gear 506 to rotate. Then the sealing rotating plate 507 is driven to rotate while the inside of the three-way container 101 is decompressed and distilled. At this time, the sealing rotating plate 507 is sucked by the air pressure. When the decompression distillation is completed, the liquid level in the internal three-way container 101 drops due to the distillation effect. Then the buoyancy block 512 is lowered, which drives the balance rotating plate 511 to rotate, and then the lifting plate 509 lifts the sealing rotating plate 507, and the sealing rotating plate 507 is reset through the reset rotating rod 508.

During the distillation process of the present invention, the liquid droplets will adhere to the inlet end, causing the liquid droplets to flow back. At this time, the refluxed liquid droplets will accumulate inside the water barrier plate 601, and the gravity of the water barrier plate 601 will gradually increase. When the ventilation opening When 602 is completely sealed by the water barrier plate 601, the distillation ends. At this time, the water barrier plate 601 descends so that the sliding plate 604 descends inside the auxiliary cylinder 605 and gradually seals the vent 602. After the distillation is completed, the rectification unit is removed, and the barrier is cleaned. The water inside the water pan 601 is reset to the water isolating pan 601 through the return spring 606 .

In the present invention, after cleaning by the cleaning unit 3 is completed, a small amount of impurities will still remain in the mesh of the filter 301, and the weight of the impurities will also increase as the use time increases. This special situation requires the vibration unit 4 to handle it. Under normal circumstances, vibration The vibration gear 405 of unit 4 meshes with the vibration clamping plate 406 to make the gravity spring rod 403 stationary. When the neutrality inside the filter 301 reaches a certain limit, the gravity spring rod 403 sinks and rotates, thereby causing the vibration gear 405 to break away from the vibration clamp. The plate 406 rotates, which in turn drives the vibration cam 402 to rotate, which in turn causes the filter screen 301 to vibrate and clean out the impurities in the mesh. When the impurities are removed, the gravity spring rod 403 resets, and the gravity gear engages with the vibration clamping plate 406 again.
