3-bromo-7-iodoquinoline

The main use of 3-mercury-7-tellurium square light is related to many fields.
In the art of alchemy, mercury is the key thing. Ancient alchemists regarded mercury as the spiritual material that can refine elixirs for longevity. "Baopuzi · Nei Chap" says: "The pill sand is burned into mercury, and the accumulation changes and becomes pill sand." Mercury in the process of alchemy has undergone many changes, and the magician wants to use it to explore the secret of longevity. And tellurium square light, although it is rarely recorded in ancient alchemy, if it has special chemical properties, it may also be noticed by alchemists and used to adjust the characteristics of elixirs.
In medical treatment, mercury has medicinal properties. " The Canon of Shennong Materia Medica lists mercury as a middle product, saying that it is "the main scabies and scabs that choose white baldness, kill skin lice, abortion, remove heat, and kill gold, silver, copper, and tin poison." However, mercury is toxic, and the dosage and usage should be extremely cautious. If tellurium square light has special pharmacology, it can also be used by doctors to treat various diseases, but the ancient books do not have detailed records of this, or it will be further explored by later generations.
In the process of making, mercury can be used for gilting. This process makes mercury and gold into amalgam, which is applied to the surface of the utensil, heated to evaporate the mercury, and the gold is attached to the table of the utensil, making the utensil beautiful. If the tellurium square light has unique physical properties, or plays a role in specific processes such as making special lustrous utensils, although no detailed ancient records have been found, it may be possible to speculate based on its characteristics.
In addition, in the way of divination of astrology, the ancients often used various strange things as a medium to communicate with the gods of heaven and earth. The flow and change of mercury seem to contain the mystery of heaven and earth; if the tellurium square light has a unique change in light and color, it may also be included in the divination of things to help divines understand the secrets of heaven, but such uses are mostly in mysterious and obscure records, which are difficult to verify with certainty.

There are many methods for the synthesis of 3-cyanogen-7-azabicyclo [2.2.1] heptane light. Under the framework of "Tiangong Kaiwu", it can be explored from the following ancient methods:
First, the synthesis is started from natural materials. In the past, most of them were based on natural products and obtained the target product through complex transformation. For example, looking for plant extracts with similar structures, like some alkaloids containing nitrogen heterocycles, which can be skillfully chemically modified, or 3-cyanogen-7-azabicyclo [2.2.1] heptane can be obtained. First, some functional groups in plant extracts are moderately dissociated by mild hydrolysis, followed by cyanidation, and cyanide groups are introduced. At the time of cyanidation, reagents such as potassium cyanide can be used to make the reaction occur smoothly at a suitable temperature and pH, so as to gradually build the target molecular framework.
Second, the combination of traditional organic synthesis reactions. In ancient methods, condensation reactions and cyclization reactions are both powerful tools for constructing complex cyclic structures. To synthesize this substance, you can first use suitable bifunctional compounds as raw materials and initially build a chain-like structure through condensation reactions. For example, a compound containing an amino group and a halogenated hydrocarbon group is catalyzed by a base to perform nucleophilic substitution condensation to obtain a chain-like precursor. Subsequently, the inner ring reaction of the molecule is used to achieve cyclization. In this process, it is necessary to precisely regulate the reaction conditions. If the temperature is slightly higher or the side reactions occur frequently, if it is too low, the reaction will be slow. According to the ancient method, in the ceramic vessel, the charcoal fire is slightly heated and the temperature is slowly increased to promote the cyclization reaction to proceed smoothly, so as to obtain the basic structure of 7-azabicyclo [2.2.1] heptane, and then the cyanide group is introduced.
Third, refer to the ancient alchemy idea. In alchemy, there are many unique methods for material transformation and purification. When synthesizing 3-cyano- 7-azabicyclo [2.2.1] heptane, you can draw inspiration from it. If the temperature and time control are extremely strict during alchemy, the synthesis of this substance also needs to be the same. During the reaction process, pay close attention to the reaction phenomenon, if the color and odor change abnormally, or suggest that the reaction deviates from expectations. And alchemy pays attention to the ratio of materials, and the amount of each reactant should be accurately calculated during synthesis to achieve the best reaction effect, so that the synthesis steps are step by step like alchemy, and the accuracy is correct, and finally the pure 3-cyanogen-7-azabicyclo [2.2.1] heptane is obtained.

3-Water is an acid solution, and 7-saltpeter square light usually refers to fire nitrate (nitric acid). Its physical properties are as follows:
3-Water, with acid, sulfuric acid, and nitric acid being the most common. Acid-colored transparent liquid has a strong pungent smell and is attractive. It is exposed to the air and placed in the air to form a white liquid at the mouth of the bottle. Because of its chlorination, it is evaporated in the air to form small droplets of acid. Sulfuric acid products are mixed with colored oil liquid, which has strong water absorption and can be used as dry, dilute sulfuric acid emits a large amount of water, and has corrosion. Nitric acid and colored transparent liquid have an irritating taste, oxidization and resistance. Nitric acid is easily decomposed by light or light, and decomposes the raw nitrogen dioxide. Dissolve in nitric acid to make it colored.
7-Saltpeter square light fire nitrate, that is, nitric acid, is usually a transparent orthorhombic or cubic crystal system or white powder. The taste is spicy and sensitive, the phase density is 2.109, the melting temperature is 334 ° C, it is easily soluble in water, and its aqueous solution is neutral. Fire nitrate is not easy to deliquescent in air, and it has a good quality. When it decomposes to a certain extent, it releases oxygen. It is one of the important raw materials for making fire. In ancient fire formulas, fire nitrate provides oxygen, so that charcoal and sulfur can burn fiercely.

The photochemical properties of 3-bromo-7-azabenzonorbornene have been investigated, and the following is based on the ancient and elegant words.
This compound has a special photochemical activity. Under light, the distribution of its molecules can be easily changed, leading to a general transformation. First, it can be reversed by light. Because light stimulates the molecule, making it high-energy, the active parts of the molecule have been changed, promoting the original phase. In this process, the angle and shape of the molecule have also been adjusted to meet the requirements of transformation.
In addition, 3-bromo-7-azabenzonorbornene or can be photoinduced. The presence of a bromine atom, due to its properties, affects the density distribution of molecules.

In addition, the photochemical properties of 3-bromo-7-azabenzobenzorbornene are diverse and subtle, and the illumination is like a reaction. It provides new ideas and methods in the fields of synthesis and materials science, which are worthy of in-depth study.

Futrinitroglycerin, made from glycerin and nitric acid, is a powerful explosive substance, and is also used in medicine to expand blood vessels. However, there are many things to pay attention to in storage and transportation.
First words storage, must be placed in a cold and dark place. Cover its sensitive nature, heat and light can promote its decomposition, and even cause explosion. The temperature of the warehouse should be controlled in a specific range to avoid direct sunlight. And the storage place should be well ventilated to prevent gas accumulation.
Furthermore, its packaging must be firm and dense. Use a special container to withstand a certain pressure to avoid the risk of leakage. Labels must clarify its nature, danger and emergency methods, so that everyone who sees it knows its risks.
As for transportation, it is very important to choose the right vehicle. It is transported in an explosion-proof and fire-proof vehicle, and it is specially guarded by a professional. During the journey, avoid bumps and sharp earthquakes, and cause them to explode due to vibration.
The journey of transportation should also comply with laws and regulations. Report to the government and get approval to move. Determine the route to avoid people and dangerous places.
The escort must be familiar with its nature and emergency measures. Prepare fire-fighting and protective equipment, and be able to respond quickly in distress to ensure the safety of people and things.
In general, trinitroglycerin should be used with caution at all times in storage and transportation. From warmth, light, packaging, vehicles, to the preparation of personnel, all should not be ignored. A little sparse is a disaster, endangering human life and wealth, so be very careful.
