Description

A kind of liquid separator for chlorinated amine preparation and extraction process

technical field

The invention relates to the field of preparation of chlorinated amines, in particular to a liquid separation device for the preparation and extraction process of chlorinated amines.

Background technique

Chloroamine, namely O-3-chloro-2-propenylhydroxylamine, is a very important pesticide and pharmaceutical intermediate, especially widely used in the synthesis of cyclohexenone herbicides, such as clethodim, chlorpyrifos ketone, cycloxydone, benzotrione, buproflomone, cyclofenazone, etc. These herbicides are ACCase inhibitors and are post-emergent selective herbicides. Grass has special effects, but the extraction process of chloramine is more complicated. Mix hydroxylamine salt, water, acetone, and then add sodium hydroxide solution, react at room temperature for 1 to 2 hours, and then add 1,3-dichloropropene and Phase transfer catalyst, heated in a water bath and controlled at a temperature of 60 to 90 °C for 5 to 10 hours, then left to stand for stratification, separate and collect the oil phase, extract the oil phase with an extractant for 2 to 3 times, and use anhydrous sodium sulfate for the extract. Drying, after a series of chemical reactions, the chlorinated amine needs to be finally extracted. The commonly used extraction method is the decompression extraction method, and the ordinary kettle body cannot achieve the desired effect during the decompression process. The principle of pressure precipitation involves Henry's law, that is, as the pressure in the kettle changes, the corresponding gas output should also change with the pressure in the kettle, so as to achieve the ideal effect of reduced pressure precipitation.

The working principle of the present invention is:

After the chloramine raw material is put into the kettle body 1, the kettle body 1 is pressurized. During the process of increasing the pressure in the kettle body 1, the gas in the kettle body 1 follows the second mounting seat that communicates with the kettle body 1. 18 enters the second trachea 19, enters the third trachea 21 communicated with the second trachea 19 from the second trachea 19, enters the first trachea 23 communicated with the third trachea 21 from the third trachea 21, and enters from the first trachea 23 to the In the cylinder block 24 connected with the first gas pipe 23, since the cylinder block 24 and the first gas pipe 23 are slidingly fitted and dynamically sealed, when the gas enters the cylinder block 24, the cylinder block 24 will be gradually moved away from the first gas pipe by the gas. The direction of the air pipe 23 is pushed out. When the cylinder block 24 is not pushed by the gas, the tension spring 26 connected with the cylinder block 24 and the first air pipe 23 is in a relaxed state, and the valve core 25 connected with the cylinder block 24 is in a state of maximum air outlet. As the cylinder block 24 is gradually pushed away from the first air pipe 23 by the pressure, the tension spring 26 will gradually tighten. As long as the pressure in the cylinder block 24 does not decrease, the tension spring 26 cannot be reset and always remains in a tight state. The body 24 is gradually pushed by the gas in the direction away from the first gas pipe 23, and the valve core 25 connected with the cylinder body 24 will also move with the advancement of the cylinder body 24. When the pressure in the kettle body 1 reaches the maximum preset value, the valve core 25 will move. The core 25 will be pushed to the designated position by the cylinder block 24. At this time, the state of the valve core 25 is the minimum gas outlet state. When the ball valve 17 is opened, the pressure inside the kettle body 1 starts to be decompressed, the gas inside the kettle body 1 decreases, and the pressure acting on the chlorinated amine raw material will also decrease. The amine will become gasified and separated from the chlorinated amine raw material. During this process, since the gas in the kettle body 1 decreases, the pressure on the cylinder body 24 in communication with the kettle body 1 will also decrease. As the pressure on the cylinder body 24 gradually decreases, the tight tension spring 26 will pull the cylinder body 24 to gradually move in the direction of the first air pipe 23 . The fixedly connected valve core 25 will move toward the first air pipe 23 along with the cylinder block 24 . When the valve core 25 moves in the direction of the first air pipe 23 , the state of the valve core 25 will gradually become the maximum air outlet state. The valve opening state of 25 is related to the pressure inside the kettle body 1. When the pressure inside the kettle body 1 reaches the maximum preset value, the valve core 25 is in the state of the minimum gas output. When the pressure inside the kettle body 1 is completely emptied, The valve core 25 is in the state of maximum gas output. Since the ball valve 17 will gradually reduce the pressure in the kettle body 1, the valve core 25 will gradually change from the minimum gas output to the maximum gas output. During this process, according to Henry's law, at a certain Under the temperature and equilibrium state, the solubility of gas in liquid is proportional to the equilibrium partial pressure of the gas, which is expressed by the formula as pB=kx, BxB, where xB is the volatile solute B (that is, the dissolved gas) in the solution. The mole fraction, pB is the pressure of the gas on the liquid surface at equilibrium, kx,B is a constant whose value depends on the temperature, pressure and the properties of the solute and solvent , it can be seen that in the process of decompression and precipitation, the solubility of the chlorinated amine raw material in the kettle body 1 decreases with the decrease of the air pressure above it. The pressure of the chlorinated amine is related, so that the chlorinated amine raw material always maintains a stable rate of dissolution in the process of the reduced pressure desolvation, so that the chlorinated amine maintains a stable volatilization state.
