4-Methylpyridine imidazole is an organic compound with unique physical properties. Although there is no direct record in ancient books, it is described in today's academic analogy as follows:
When it is at room temperature, it is mostly in a solid state, with a fine texture. It has a bright luster, just like finely crushed Qiongyu. The melting point is in a specific range, about [X] ° C, and it gradually melts when heated, turning into a flowing liquid, which is like a mountain stream, which is smart and tangible. The boiling point is also fixed, about [X] ° C. At a specific temperature, it liquefies into gas, rises in the air, and disperses invisibly. In terms of solubility, 4-methylpyridyl imidazole is slightly soluble in water solvents, and can only make some molecules discrete in water, making it difficult to form a uniform state; however, organic solvents, such as ethanol, acetone, etc., dissolve quite well, and can blend with solvents infinitely, just like water emulsion, forming a uniform and stable system.
Its density is slightly larger than that of water, and it is placed in water, slowly settling, like a stone sinking into the abyss, showing a dignified state. The smell is weak and specific, not pungent and intolerable, but under the slight smell, there is a unique smell, just like the subtle fragrance emitted by ancient trees in the mountains. It is difficult to express, but it is unique.
In addition, the vapor pressure of 4-methylpyridyl imidazole is low at room temperature, the volatility is weak, and it is not easy to spread rapidly in the air. It is like a pearl hidden in the dark. Although it has brilliance, it is not easily exposed. Its refractive index also has a specific value. When the light passes through, the light is deflected to a certain extent, showing unique optical characteristics, which seem to be able to refract the subtleties and reflect different beauty.

4-Methylpyrimidine is an organic compound with unique chemical properties. This compound contains the structural unit of pyrimidine and pyrimidine. The pyrimidine ring and pyrimidine ring are fused in a specific way, resulting in its properties different from monocyclic pyrimidine or pyrimidine.
In terms of physical properties, 4-methylpyrimidine is mostly a solid at room temperature. Due to the interaction of van der Waals force and hydrogen bonds between molecules, the melting point and boiling point are relatively high. Its solubility is related to molecular polarity. It can be dissolved in some polar organic solvents such as ethanol and acetone, but its solubility in water is limited because it is not a strongly polar molecule.
Chemically, the nitrogen atom in 4-methylpyrimidine has a lone pair of electrons, which is basic and can react with acids to form salts. The electron cloud density distribution of the carbon atoms on the pyrimidine ring and the pyrimidine ring is uneven due to the electronic effect of the nitrogen atom. In the electrophilic substitution reaction, the reactivity and localization law are different from that of the benzene ring. For example, electrophilic reagents are more likely to attack positions with relatively high electron cloud density.
In addition, the methyl group of 4-methylpyrimidine has certain reactivity, and can undergo oxidation and substitution reactions under appropriate conditions. This compound is widely used in the field of organic synthesis and can be used as a key intermediate. By modifying and derivatization of its structure, many organic compounds with biological activity or special functions can be prepared, which is of great significance in the fields of medicinal chemistry and materials science.

4-Methylimidazole is a possible by-product in the production of caramel color. Although the production method of 4-methylimidazole is not directly mentioned in Tiangong Kaiwu, similar ideas can be explored from the records of ancient related chemical processes.
In ancient times, certain substances were prepared, and they were often separated, purified and converted by different methods according to the characteristics of the substance. Caramel color production is made by heating sugar substances and other means.
To make 4-methylimidazole, its properties should be known first. 4-Methylimidazole is formed by the condensation reaction of glyoxal, formaldehyde and ammonia. This reaction needs to be carried out under specific conditions, such as suitable temperature, pH and catalyst.
If the ancient analogy is used, it is necessary to find a suitable "medicinal introduction" to promote the reaction. Such as ancient alchemy and pharmaceuticals, special ores, plants and trees are often used as references to change the chemical reaction process. In this reaction, similar substances that can promote the condensation of glyoxal, formaldehyde and ammonia can be found.
Temperature control is also crucial. "Tiangong Kaiwu" contains many processes that require strict heat conditions. In this reaction, it may be necessary to explore the appropriate heating method and heat to make the reaction proceed stably. Or if the ancient method of firing ceramics is used to adjust the heat according to different stages, so that the reaction develops in the direction of generating 4-methylimidazole.
pH adjustment cannot be ignored. Ancient dyeing and other processes are known to adjust pH such as plant ash and water. In this reaction, the solution formed by natural substances can be used to adjust the pH of the reaction system and generate 4-methylimidazole.
Although there is no detailed description of the production of 4-methylimidazole in "Tiangong Kaiwu", the wisdom and process ideas of the ancients can provide inspiration for exploring its production method. By understanding the properties of the substance and controlling the reaction conditions, we can explore suitable production methods.

4-Methylpyrimidine requires careful attention during storage and transportation.
When storing, the first choice of environment. It must be selected in a cool, dry and well-ventilated place, and must not be placed in a high temperature or humid place. Due to high temperature, it is easy to cause its volatilization to accelerate, or cause chemical reactions; moisture may cause it to deteriorate and damage its quality. This is the basis for ensuring its chemical stability.
In addition, isolation from other substances is also crucial. 4-Methylpyrimidine should not be co-stored with strong oxidants, strong acids, strong bases, etc. Strong oxidizing agents have strong oxidizing properties, or react violently with 4-methylpyrimidine, causing combustion and explosion; strong acids and bases will react chemically with them, changing their chemical structure and losing their original characteristics.
During transportation, the packaging must be solid and stable. Choose suitable packaging materials to ensure that the packaging will not be damaged during handling and turbulence. If the packaging is damaged, 4-methylpyrimidine leakage will not only pollute the environment, but also cause safety accidents.
The cleanliness and dryness of the transportation vehicle should not be ignored. If other chemicals remain in the transportation vehicle, or interact with 4-methylpyrimidine. And the transportation process needs to be strictly controlled by temperature, follow the established transportation specifications, and must not be transported over temperature.
In addition, operators also need to undergo professional training. Familiar with the characteristics of 4-methylpyrimidine and pyrimidine, master the correct storage and transportation methods. In case of emergencies, such as leakage, fire, etc., it can be handled quickly and properly to prevent the expansion of accidents and ensure that personnel safety and the environment are not seriously damaged.
