3-Bromobenzothiophene

3-Bromopropene is an organic compound with unique physical properties.
Looking at its properties, 3-bromopropene is a colorless to light yellow liquid at room temperature and pressure. It is volatile in the air and has a pungent and irritating odor. Its boiling point is about 70 ° C and its melting point is about -119 ° C. Such a melting boiling point makes it a liquid at room temperature and relatively easy to gasify. Due to its low boiling point, it is easy to transform into a gaseous state in a heated or open environment.
In terms of solubility, 3-bromopropene is slightly soluble in water, but it can be miscible with organic solvents such as ethanol, ether, and chloroform. This solubility is related to its molecular structure. Its molecules have a certain polarity, but they also contain hydrophobic hydrocarbons, which makes it difficult to dissolve in water with strong polarity, but can dissolve with organic solvents with similar polarity.
The density of 3-bromopropylene is greater than that of water, about 1.398g/cm ³. When mixed with water, it will sink to the bottom of the water, and the stratification phenomenon is significant. In addition, its vapor is heavier than air, and it is easy to spread close to the ground when leaking, posing a safety hazard.
In summary, the physical properties of 3-bromopropylene, such as liquid, special odor, specific melting boiling point, solubility and density, need to be carefully considered when storing, transporting and using it to ensure safety and rational use.

3- The main purpose of drinking wine is probably the following.
First, it is used to benefit the stomach. If a person can't eat, it will be stuck in the stomach, causing stuffing in the stomach and defecation in the abdomen. This way, the wine can be attacked and gathered, so that evil can have a way out. And the wine is good, it can be used to help the power of the machine to speed up the disease, speed up the excretion, so that the stomach can pass, so that the stomach can pass. For example, some of the attacks in "Cold", or accompanied by wine, in order to increase the effect of passing the heart.
Second, to dissipate blood stasis and relieve pain. The bruising, the blood stasis stopped, and the blood stasis was painful. The wine can be introduced to new, and the wine can promote blood circulation and pass the blood. Serving both can promote the dissipation of blood stasis and cause pain. For example, if the pain in the limbs is caused by blood stasis, the combination of wine can make blood stasis descend, and the purpose of reducing pain is achieved.
Third, lead down. The downward nature of the wine can lead the power of the wine to the lower focus. There are pathogens such as the lower focus and the lower focus. With the help of wine, the lower focus can be injected into the lower focus, and the lower focus can be cleared and improved. For example, treating the bleeding, etc., of the lower focus, etc., and taking the wine, the power can be concentrated on the lower focus to relieve the evil and poison.
Fourth, help the water. If the water fails, the water will stop, and the limbs will be watered, and the urine will be unfavorable. The wine can improve the waterway, and the wine can pass the water. The two are combined, and the water can be helped, and the water can be excreted and improved. And wine can increase the power of water, so that the evil of water can come out.

There are various ways to synthesize 3-bromoquinoline and imidazole, which can be explored from the classical organic synthesis method.
First, using o-phenylenediamine and bromoaromatic aldehyde as starting materials, in a suitable solvent, under the catalysis of acid or base, the intermediate is first condensed to form Schiff base. Then, under the action of heating or catalyst, the intermediate undergoes intramolecular cyclization, and 3-bromoquinoline and imidazole can be obtained. This process is like "water and fire and soil synthesis" in Tiangong Kaiwu, where the reactants interact to achieve synthesis under specific conditions. The control of reaction conditions is crucial. The choice of solvent, the adjustment of pH, and the temperature all affect the yield and purity of the product.
Second, quinoline derivatives are used as the starting material, and bromine atoms are introduced through bromination reaction at a specific position. Subsequently, it reacts with reagents containing imidazole structure under suitable reaction conditions to realize splicing of the two and construct 3-bromoquinoline and imidazole structure. This is just like the use of "clever method" in "Tiangong Kaiji", ingeniously selecting raw materials and combining them in a suitable method. The reaction process needs to pay attention to the selectivity of bromination position, avoid the occurrence of side reactions, and ensure the formation of target products.
By designing a multi-step reaction route, common simple organic compounds can be used as the starting materials to gradually build the required functional groups and skeletons. For example, small molecules containing quinoline and imidazole fragments are synthesized first, and then connected by a coupling reaction to finally obtain the target product. This route requires precise planning of each step of the reaction, just like the creation of "Tiangong Kaiwu", carefully considering the connection and influence of each reaction step to ensure the smooth progress of the reaction and the quality of the product.

Those who transport and store three -%E6%BA%B4%E8%8B%AF%E5%B9%B6%E5%99%BB%E5%90%A9 should be aware of all things and must pay attention.
First heavy packaging. This medicine has special properties, and the packaging must be strong and tight to prevent leakage. The material used must be able to withstand its erosion and resist various external influences, such as changes in temperature and humidity. Otherwise, the medicine will leak, which will not only damage its medicinal power, but also endanger the surrounding things and people.
The second is the storage environment. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources. Light must also be avoided, and its efficacy will be reduced due to light or changes in its ingredients. The temperature should be controlled within a specific range. If it is too high, the medicine will deteriorate easily, and if it is too low, it will also affect its properties.
Furthermore, when transporting, the traffic must be smooth to prevent its vibration and collision. Vehicles should be clean and stain-free, and equipped with appropriate temperature control equipment. When loading and unloading, workers must also be careful, handle it with care, and do not engage in rough work to avoid the bottle breaking.
In addition, when mixed with other drugs or articles for storage, its chemical properties must be carefully inspected to prevent their interaction and danger. If it is unclear, when consulting a professional person, you must not make any unauthorized claims.
And the storage and transportation place should be clearly marked, showing the name of the drug, its nature, precautions, etc., so that everyone can know. It is also necessary to check it regularly to see if the packaging is damaged and whether the environmental conditions are suitable. If there is an abnormality, the speed of disposal, do not delay, so as not to cause trouble. In this way, Fang Bao three -%E6%BA%B4%E8%8B%AF%E5%B9%B6%E5%99%BB%E5%90%A9 in the process of storage and transportation.

3 - What is the impact of natural environment and human health? All things in the world have advantages and disadvantages, and natural environment is no exception.
Natural environment is the residue of oil, often used in roads and waterproofing projects. When it is under construction, it is added to the high temperature, and it will release many harmful substances, such as many aromatics. Such substances are scattered in the air. If people inhale them, it will cause them to be unable to breathe, and they will be afraid of respiratory diseases and even cancer for a long time. Moreover, its pungent smell also affects people's body and mind, making people uneasy.
And natural environment is one of the most harmful products. On the contrary, it is a good thing to beautify waters and purify water. However, if the water is polluted by green, the harm of green may affect the environment of the environment. If the water is polluted by green, the number of harmful substances in the water will increase, which will affect the health of the water, causing it to dry up, have a short flowering period, and even survive.
Furthermore, if people eat green-polluted food, it will also endanger their health. Harmful substances gather in the environment, causing diseases.
Of course, the harm of green cannot be ignored, and its environment and human health have many unfavorable effects. And the things that are originally auspicious and auspicious may be damaged because of green. Therefore, in life, avoid the harm of green, and the beauty of green, so as to ensure the cleanliness of the environment and the health of people.
