    What are the main uses of 2-iodoaniline?
    The main use of 2-% of the time, it has the effect of promoting blood circulation and relieving pain.
    Its work of promoting blood circulation and relieving pain is beneficial to blood stasis. If the person does not work every month, abdominal pain is caused, or if it doesn't work, it can be used to promote blood circulation and remove blood stasis, so that the menstrual period is normal. And in the case of bruises, blood stasis and pain, it can also be used to promote blood circulation and eliminate blood stasis, dissipate pain, and promote health.
    To remove pain and relieve pain, it is especially good to treat pain. Its nature rises and disperses, it can improve the eyes, and it can be used for pain caused by cold, cold, and pain. If it is cold and painful, it is often combined with hemp and aspergillin to relieve the pain and improve the ability to dissipate cold and relieve pain; if it is painful, it can be used with chrysanthemum, plaster, etc., to evacuate the pain and relieve the pain; if it is painful, it is often used with Qiang Huo, Huo Huo, etc. to remove the pain. In addition, the pain caused by evil and evil in other parts of the body can also be beneficial, such as the pain of arthralgia.
    In addition, it is also commonly used to treat blood. The mother of blood, the mother of blood, depends on blood. Ligusticum can not only promote blood circulation, but also be feasible, so that blood circulation can be improved, for the purpose of blood circulation and blood circulation, and for the diseases caused by blood discord, all have the ability to cure.

    What are the physical properties of 2-Iodoaniline?
    Algae is a marine plant, mostly grown in the sea mud. Its physical characteristics are as follows:
    - ** Shape-specific **: Algae plants grow on the sea floor, growing on the bottom of the sea. Its creeping spread, like a meandering, walks on the seabed, stretching around to fix its own absorption points. The patches are like this, the ground is soft, the sea is full of currents, 20 cm, 20 mm, flat, and bright. Each piece is usually 2 pieces, arranged in a whole way, as carefully placed, showing the beauty of natural order.
    - ** Color Sense **: Its color is more emerald or light, refreshing the eyes. This color comes from the rich nutrients in the film, which help it perform photosynthesis. The surface of the film must be bright, as if covered with a thin layer, which can not only reduce water loss, but also protect the film from seawater rot. The feeling of softness and flexibility, which is not easy to fold in the water flow, giving it a good performance in the marine environment.
    - ** Specific gravity density **: The specific gravity of Algae is slightly smaller than that of seawater, so it can float in the water without sinking to the bottom. This feature makes it fully accepting light and conducive to photosynthesis. There are many cavities in the bottom of the body, and some cavities are filled with water, which does not provide buoyancy, which helps the plant to breathe in water and maintain normal physiological activities. Its density is relatively small, [X] grams/cubic centimeter, and the density keeps it just right in the seawater. It neither floats to the surface to be exposed to the hot sun, nor sinks to the bottom of the sea into darkness.
    - ****: Due to living in the environment where tides, ocean currents and other currents are changing and proliferating, the algae have evolved good performance. In case of water currents, its shape can be curved, and the direction of the current can be bent to avoid force. When the current recedes, it can quickly restore its original form and perform normal life activities, such as photosynthesis, absorption, etc. This property is an important guarantee for its survival and reproduction in the marine environment.

    What are the synthesis methods of 2-iodoaniline?
    2 - There are many synthetic methods of Bupleurum ointment, each with its own strengths, which are described in detail below.
    One is the decoction and concentration method. Take an appropriate amount of Bupleurum first, select it clean and place it in a large kettle, add enough water, and fry it slowly. At the beginning, the fire was slightly intense. After the water boils, adjust it to a low heat, and cook it slowly to fully dissolve the active ingredients of Bupleurum. Repeat the decoction several times, combine the decoction liquid, and then filter out the residue with a fine sieve to obtain a clarified liquid. Then put the liquid in an open vessel, heat and concentrate it on medium heat, and stir it constantly during this period to prevent burning. When the liquid is concentrated to the desired consistency, it is Bupleurum ointment. This method is relatively simple to operate, and can better retain most of the components of Bupleurum, but it takes a long time and requires high temperature control.
    The second is the solvent extraction method. Select a suitable organic solvent, such as ethanol, etc., pulverize Bupleurum and mix it with the solvent in a certain proportion, and seal it in the container. Or dip it at room temperature and stir it regularly to make the solvent fully penetrate the medicinal materials to dissolve the active ingredients; or use the method of heating and reflux to speed up the extraction. After the extraction is completed, the residue is filtered to remove and the extract is collected. Then the solvent is recovered by distillation and other means, and then concentrated to obtain Bupleurum paste. This method has high extraction efficiency and can selectively extract specific ingredients. However, the use of organic solvents needs to pay attention to safety and residual issues.
    The third method is supercritical fluid extraction. This is a more advanced method, using the fluid in the supercritical state as the extractant. Supercritical fluid has both the diffusivity of gas and the solubility of liquid, which can efficiently extract the active ingredients in Bupleurum. The Bupleurum is placed in the extraction kettle, and the supercritical fluid is introduced to control the appropriate temperature, pressure and other conditions to dissolve the active ingredients in the supercritical fluid. Then the pressure is lowered and cooled by the separation kettle, so that the supercritical fluid is restored to a gaseous state and separated from the extracted components, so that the high-purity Bupleurum paste raw material can be obtained, and then the subsequent treatment is made into Bupleurum paste. The product obtained by this method has high purity and no solvent residue, but the equipment requirements are high and the cost is also high.
    What are the precautions for 2-iodoaniline during storage and transportation?
    In the process of storage and transportation, when answering in classical Chinese, the following things should be paid attention to:
    The first word of storage, the nature of the two-flavor insect likes shade and humidity, and is afraid of dry heat and strong light. Therefore, the storage place should be selected in a cool and dry place, away from direct sunlight, and well ventilated. If placed in a closed and airtight place, it is easy to cause mildew and rot. The storage utensils used should also be paid attention to. It is better to use porcelain urns and crock jars, because they can keep the environment relatively stable and prevent the intrusion of external moisture and odor. And the urns and jars need to be clean and stain-free. First, they should be roasted with fire to remove the moisture before the insects are included. You can also sprinkle a little lime in the container to absorb moisture. However, the lime should not be in direct contact with the insects, and it can be separated by thin paper to avoid hurting the insects.
    As for transportation, the two flavors are brittle and fragile. When handling, you must handle them with care to avoid violent vibrations and collisions. The transportation equipment should be lined with soft objects, such as cotton wool, hay, etc., so that the insects are stable on the way and will not be damaged. And when transporting, you should pay attention to climate change. In the hot summer season, to prevent it from being heated and rotten, you can put ice next to it to lower the surrounding temperature; when it is cold, you may be afraid of freezing and stiffening, so you need to wrap it in felt cloth to protect it from the outside cold. If it takes a long time on the way, the state of the insect should be checked regularly. If there is any abnormality, it should be disposed of quickly. In this way, the quality and efficacy of the two-flavor insect can be guaranteed during storage and transportation.
