What are the physical properties of 1-chloro-3,5-dibromo-4-nitrobenzene?
"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. The book describes many technological technologies and product characteristics in detail. The physical properties of brine, dialum and mirabilite are described in ancient Chinese.
The brine is salty and cold in nature. The color is clear or turbid, and it is often found in salt ponds and brine. Its taste is very salty, highly corrosive, and it feels greasy on the skin. Brine can be used to make salt and is also an important raw material for chemical industry. With it, salt crystals can be obtained, which are crystal clear. In ancient times, the extraction and application of brine was the priority of salt workers.
Dialum, different types, common green alum, alum, etc. Green alum is green in color and has a sour taste. When placed in the air, it is easy to oxidize and change color. Its texture is brittle and ground into powder. Green alum can be used for dyeing, pharmaceuticals, etc. Alum is white as snow, in the form of lumps or powders. Its taste is sour and dry. Alum is useful in water purification, papermaking, medicine, etc. When used in water purification, it can make impurities in the water coalesce and settle.
Mirabilite, white in color, like frost and snow, brittle and fragile. Its taste is salty and bitter, and cold in nature. Mirabilite is easily soluble in water, and when dissolved, it absorbs heat, reducing the water temperature. In medicine, mirabilite has the effect of laxative; in the industrial field, it is also an important chemical raw material, which can be used to make glass, detergents, etc.
Halogen, dialum and mirabilite, each with unique physical properties, played an important role in many aspects of ancient production and life, and were used by the ancients to promote the development of craftsmanship at that time.

What are the chemical properties of 1-chloro-3,5-dibromo-4-nitrobenzene?
Mercury, commonly known as mercury, is a liquid metal at room temperature and pressure, and has the following chemical properties:
First, mercury has certain reductivity. Under heating conditions, mercury can react with oxygen to form mercury oxide, and this reaction shows that mercury can lose electrons and be oxidized. For example, although this reaction is not detailed in "Tiangong Kaiwu", it can be known from the general chemical properties of metals. In this reaction, mercury atoms lose electrons and become mercury ions, and oxygen gains electrons and becomes oxygen ions, which combine to form mercury oxide.
Second, mercury can react with sulfur. Mercury and sulfur powder are mixed and ground to form mercury sulfide. This reaction is extremely rapid and thorough. If mercury is spilled in the laboratory, it is often covered with sulfur powder to prevent mercury volatilization from causing harm. This property indicates that mercury has a strong affinity for sulfur. "Tiangongkai" in the content of metal processing, or indirectly reflects the reaction characteristics of such substances. In this reaction, mercury and sulfur atoms are recombined to form stable mercury sulfide compounds.
Third, mercury can form alloys with certain metals, namely amalgams. If mercury is contacted with metals such as gold and silver, amalgams can be formed. In ancient times, amalgams were used to extract metals such as gold and silver. "Tiangongkai" records related to metal smelting, or involves the application of amalgam characteristics. The formation of amalgam process, mercury and other metal atoms mix with each other, changing the original physical and chemical properties of the metal.
Fourth, mercury compounds have various chemical properties. For example, mercury chloride has a certain degree of oxidation; mercury sulfide has relatively stable chemical properties and exists in the form of cinnabar in nature. Although the properties of various minerals and metal compounds are not explained in detail in "Tiangong Kaiwu", from the perspective of overall ancient chemical cognition and practice, the properties of mercury compounds may be reflected and applied in alchemy, medicine, pigments and other fields.

What are the synthesis methods of 1-chloro-3,5-dibromo-4-nitrobenzene?
There are currently methods for preparing 1-bromo-3,5-diene-4-carbonyl naphthalenes as follows:
First, suitable naphthalene derivatives can be initiated. First, the naphthalene with appropriate substituents is taken, and under suitable reaction conditions, the bromination reaction is carried out with a brominating reagent. The brominating reagent used, such as bromine ($Br_2 $), can selectively introduce bromine atoms at specific positions in the naphthalene ring under the action of a catalyst to obtain bromine-containing naphthalene intermediates. This process requires fine regulation of the reaction temperature, time and reagent dosage to ensure that the bromine atoms are accurately connected to the target check point.
Subsequently, the construction of the diene structure is targeted. It can be formed by the classic alkene-forming reaction in organic synthesis, such as Wittig reaction or Horner-Wadsworth-Emmons reaction. If Wittig reaction is used, a suitable phosphorus Yelid reagent needs to be prepared, and it needs to be reacted with the carbonyl-containing naphthalene intermediate. Under mild conditions, the nucleophilic addition and elimination steps are performed to form the desired bisene structure. This step requires attention to the purity of the reagent and the anhydrous and oxygen-free environment of the reaction system to improve the reaction yield.
As for the introduction of carbonyl groups, an oxidation reaction can be used. For example, a specific alcohol intermediate is oxidized with a suitable oxidizing agent, such as Jones reagent ($CrO_3 - H_2SO_4 $) or Dess-Martin reagent. If the naphthalene derivative is first introduced with appropriate hydroxyl groups and then oxidized, the carbonyl group can be efficiently obtained. This oxidation reaction requires precise control of the amount of oxidizing agent and reaction conditions according to the characteristics of the substrate to prevent excessive oxidation.
Second, the strategy of gradually constructing naphthalene rings can also be used. First, simple aromatic compounds are used as raw materials and gradually spliced to form a naphthalene ring skeleton through Friedel-Crafts reaction. In the process of constructing naphthalene rings, bromine atoms, alkenyl groups and carbonyl groups are introduced at the same time or successively. For example, first, the Friedel-Crafts acylation reaction is carried out with halogenated aromatics and acyl halides catalyzed by Lewis acid, and carbonyl groups are introduced, and then bromine and alkenyl groups This strategy requires careful planning of the reaction sequence and conditions of each step to avoid side reactions and ensure the purity and yield of the final product.
All these methods require the skill of organic synthesis and the deep understanding of the reaction mechanism to produce high-purity 1-bromo-3,5-diene-4-carbonylnaphthalene.

What are the precautions in the preparation of 1-chloro-3,5-dibromo-4-nitrobenzene?
In the process of baking licorice, you need to pay attention to all things, which are related to its efficacy and quality.
The first heavy medicinal materials should be selected. Licorice must be selected from the best, its quality is strong, its color is moist, and its taste is sweet. And it should be checked for insect-eaten or mildew. If there is such a situation, it must be discarded to avoid spoiling the whole agent. After purchasing licorice, store it properly in a dry and ventilated place to prevent it from getting damp and deteriorating.
Times and processing temperature. Use 1 + -salt-3,5-diliquid-4-carboxypyridine as the processing agent, and the ratio of licorice to licorice should be accurate. According to ancient prescriptions and pharmacology, it cannot be increased or decreased at will. When processing, the size and duration of the fire are the key. If the fire is large, it will be easy to burn, which will damage its medicinal properties; if the fire is small, it will not be transparent and the effect will be difficult to complete. At the beginning, it is advisable to start with a medium fire, wait for the licorice and the processing liquid to gradually melt, and then adjust it to a low fire and slowly bake. During this time, turn it frequently to make it evenly heated until the color of the licorice changes and the texture reaches the right level.
Furthermore, it is the control of the environment. The processing place needs to be clean, free of dust and odor interference. Air humidity is also affected. If the humidity is too high, the licorice is easy to absorb moisture, which is unfavorable to preservation and medicinal efficacy. If the humidity is too low, it may be too dry and brittle. Generally speaking, the humidity should be maintained at 40% - And the ventilation of the processing place should also be good, which not only helps the water vapor and odor to dissipate, but also ensures the fresh processing environment.
There are operating norms. The person who makes the processing should wash his hands, wear clean clothes and gloves to prevent impurities from mixing in. The utensils used, such as pots, shovels, etc., must be clean and stain-free, and cleaned and disinfected regularly. When taking the processing liquid and licorice, the measuring tool should be accurate to ensure that the dosage is correct. The operation process should be concentrated and not distracted. Follow the steps in sequence, and do not miss or reverse.
After the licorice is processed, it should not be neglected for subsequent storage. It should be packed in a clean container, sealed, and placed in a cool, dry, and dark place. And regular inspection, if any abnormalities, such as moisture return, discoloration, etc., should be treated in time to ensure its long-term efficacy.
