2,6-dicyanopyridine

2% 2C6-diacetylpyridine, although this substance did not have a completely accurate corresponding name in ancient times, it was inferred due to its properties and possible uses, or it may have functions such as assisting combustion and catalysis.
In the way of alchemy and pharmaceuticals, it may be able to support combustion. In the art of alchemy, if you want to refine the magic pill, the temperature is the key. The fire needs a continuous and stable high temperature. If 2% 2C6-diacetylpyridine is placed in it, it may increase the fire and promote the refining of alchemy. Such as the ancient alchemists, often seek things to help the fire, or with sulfur and other flammable things, this diacetyl pyridine or have similar effects, with its characteristics, make the fire, accelerate the fusion of drugs, reaction, to become the essence of medicinal pills.

2% 2C6-diethylaminopyridine is an important intermediate in organic synthesis. There are several common methods for its synthesis:
First, 2-chloropyridine and diethylamine are used as raw materials. These two are added to a suitable solvent, such as toluene, with an acid binding agent, such as potassium carbonate, heated and stirred to promote the reaction. During the reaction, the nitrogen atom of diethylamine initiates nucleophilic substitution at the check point of the chlorine atom of 2-chloropyridine, and the chlorine atom leaves to obtain 2% 2C6-diethylaminopyridine. The key to the reaction is to precisely control the reaction temperature and time. If the temperature is too high or the time is too long, it may cause side reactions and reduce the purity of the product. For example, if the temperature exceeds 120 ° C, or the reaction time exceeds 10 hours, or there is excessive substitution of diethylamine, multiple substituted impurities will be formed.
Second, start from 2-hydroxypyridine. First, 2-hydroxypyridine is converted into a corresponding halide, such as 2-bromopyridine, which is often achieved by reagents such as phosphorus tribromide. Then, 2-bromopyridine reacts with diethylamine according to the nucleophilic substitution mechanism to obtain the target product. The advantage of this route is that 2-hydroxypyridine has a relatively wide source and low cost. However, the conversion to halide requires attention to the mildness of the reaction conditions. Due to the relatively active structure of 2-hydroxypyridine, the pyridine ring structure is easily destroyed under severe conditions.
Third, pyridine-2% 2C6-dicarboxylic acid is used as the starting material. Pyridine-2% 2C6-dicarboxylic acid is first esterified into the corresponding ester, and then reduced by reduction means, such as reduction with lithium aluminum hydride, to obtain 2% 2C6-dihydroxymethylpyridine. Next, 2% 2C6-dimethylol pyridine and diethylamine are aminated in the presence of acidic catalysts such as p-toluenesulfonic acid, and finally 2% 2C6-diethylamino pyridine is obtained. Although this method has many steps, the reaction selectivity of each step is better, which can effectively improve the yield and purity of the product.
Each method for synthesizing 2% 2C6-diethylamino pyridine has its own advantages and disadvantages. In actual synthesis, many factors such as the availability of raw materials, cost, difficulty of reaction conditions, and the requirements for product purity and yield need to be comprehensively considered to choose the best synthesis path.

2% 2C6-diacetylpyridine, its physical properties are as follows:
This substance is a solid at room temperature and pressure, and its appearance is often white to light yellow crystalline powder with a certain luster. The melting point is about 96-98 ° C. When the temperature rises to this range, the substance gradually changes from solid to liquid. Its boiling point is in a higher temperature range, about 305 ° C. When this temperature is reached, the substance will change from liquid to gaseous.
2% 2C6-diacetylpyridine is slightly soluble in water. Although it contains polar groups such as nitrogen atoms in its molecular structure, the existence of the overall carbon chain structure and pyridine ring makes it less soluble in water.

2% 2C6 -diethylaniline is an organic compound. When storing and transporting, the following items should be paid attention to:
First, the storage environment is very important. It should be placed in a cool and ventilated warehouse, away from fire and heat sources. Because of its flammability, it can be burned in case of open flame and hot topic, so fire prevention is extremely critical. The warehouse temperature should not exceed 37 ° C to prevent its volatilization from being intensified due to high temperature and adding safety hazards.
Second, it must be stored separately from oxidants and acids, and should not be stored together. 2% 2C6 -diethylaniline in contact with oxidants, easy to cause severe oxidation reaction, or cause combustion or even explosion; mixed with acid substances, or chemical reaction will occur, damage the packaging container, and then lead to leakage.
Third, the storage container must be well sealed. This substance is volatile, and poor sealing will cause it to evaporate into the air, not only causing material loss, but also volatile gases or harming the environment and human health.
Fourth, the transportation process also needs to be cautious. Transportation vehicles should be equipped with corresponding varieties and quantities of fire equipment and leakage emergency treatment equipment. In summer, it is best to transport in the morning and evening to avoid high temperature periods to prevent danger caused by excessive temperature. The trough (tank) car used during transportation should have a grounding chain, and holes can be set in the trough to baffle to reduce shock and generate static electricity. Static electricity may also cause combustion and explosion accidents.
Fifth, when handling, it should be handled lightly and lightly to prevent damage to packaging and containers. If the packaging is damaged, 2% 2C6-diethylaniline leaks, which will not only pollute the environment, but also cause harm to contact personnel.
Sixth, during transportation, it should be protected from exposure to sun, rain, and high temperature. Exposure to sun and rain or damage to packaging, high temperature will make the material properties unstable and increase the risk factor. Only by strictly following the relevant requirements during storage and transportation can the safety of 2% 2C6-diethylaniline be guaranteed to the greatest extent and accidents be avoided.
