This substance is called 2,4,6-trimethylpyridine. It is like water. It is a colorless to light yellow transparent liquid at room temperature and has a special odor. Its boiling point is quite high, about 171 ° C, and its melting point is low, nearly -45 ° C. The density is slightly higher than that of water, about 0.926g/cm ³.
2,4,6-trimethylpyridine is slightly soluble in water, but easily soluble in organic solvents such as ethanol and ether. Due to its molecular structure, the nitrogen atom of the pyridine ring has lone pairs of electrons, which can interact with organic solvent molecules, so it has good solubility.
In terms of chemical properties, 2,4,6-trimethylpyridine is a weakly basic substance. The nitrogen atom of the pyridine ring can accept protons and react with acids to form salts. Its alkalinity is weaker than that of aliphatic amines, but stronger than that of anilines. Due to the conjugation effect of the pyridine ring, the electron cloud density on the nitrogen atom decreases, and the attraction to protons weakens.
2,4,6-trimethylpyridine can also participate in electrophilic substitution reactions. The electron cloud density on the pyridine ring is uneven, and the electron cloud density at the α and γ positions is lower than that at the β position, so the electrophilic substitution reaction mostly occurs at the β position. In addition, its methyl group is affected by the pyridine ring and has certain reactivity, which can occur reactions such as oxidation.
In the field of industry and scientific research, 2,4,6-trimethylpyridine is widely used. It can be used as a solvent and catalyst, and is also used in organic synthesis such as drugs and dyes.

2% 2C4% 2C6-trimethylpyridine is an organic compound. It has many chemical properties, which are described as follows:
First, the alkalinity is significant. The nitrogen atom of 2,4,6-trimethylpyridine contains lone pairs of electrons, which can accept protons and is alkaline. In aqueous solution, it can react with acids to form corresponding salts. For example, when interacting with hydrochloric acid, 2,4,6-trimethylpyridine hydrochloride is formed. This property makes it widely used in the absorption, separation and catalytic reaction of acidic substances.
Second, the activity of nucleophilic substitution is high. The carbon atom on the pyridine ring is in an electron-deficient state due to the electronegativity of the nitrogen atom. When encountering nucleophiles, leaving groups such as halogen atoms on the pyridine ring are easily replaced by nucleophiles. For example, when co-heating with sodium hydroxide solution, if there are suitable halogen atoms attached to the pyridine ring, the halogen atoms can be replaced by hydroxyl groups.

Treated with strong oxidants such as potassium permanganate, the pyridine ring may be oxidized and destroyed to form oxidation products such as carboxylic acids; while with mild oxidant action, or selective oxidation of side chain methyl groups, oxygen-containing functional groups such as aldehyde or carboxyl groups are formed.
Fourth, alkylation and acylation reactions are prone to occur. In the presence of an appropriate catalyst, the nitrogen atom of 2,4,6-trimethylpyridine can be alkylated with halogenated hydrocarbons to form quaternary ammonium salts; it can also be acylated with acyl halide or acid anhydride to introduce acyl groups on nitrogen atoms. These reaction products are of great significance in the fields of organic synthesis and medicinal chemistry.
Fifth, good coordination ability. The nitrogen atom of 2,4,6-trimethylpyridine can be used as a ligand to form a coordination compound with metal ions. With this coordination effect, it can be used for the separation and purification of metal ions, and can also participate in metal catalytic reactions as a ligand to improve catalyst activity and selectivity.

First take the amount of raw material, often with a compound group. For example, with a specific compound starting material, the compound needs to have a functional group that can be reversed, in order to facilitate the introduction of trimethylphenyl.
Replace the reactive element with the reactive element and the reactive element. Such as the use of reactive trimethylbenzene, such as Grignard (RMgX, R-group, X-element), in a suitable solution, at a certain degree and reaction, the atom of the reactive trimethylbenzene is replaced by a reactive group, and the trimethylphenyl group is introduced into the target molecule.
Or use a Friedel-Crafts alkylation reaction. With an aromatic substrate, in the presence of Lewis acid catalysis (such as AlCl, etc.), the trimethylphenyl is substituted with trimethylbenzene or allyltrimethylbenzene to form a 2%2C4%2C6-%E4%B8%89%E7%94%B2%E5%9F%BA%E5%90%A1%E5%95%B6 molecule.
After the reaction, because the reaction system often contains raw materials, by-products, etc., it is necessary to take steps to improve the reaction. You can use the method of steaming, according to the difference between the boiling of each object, to distinguish the object from the eye; or use the method of column precipitation, according to the difference in the distribution of the substance in the stationary phase of the flow phase, until the purpose of the separation, in order to obtain a high degree of 2%2C4%2C6-%E4%B8%89%E7%94%B2%E5%9F%BA%E5%90%A1%E5%95%B6.
Of course, the 2%2C4%2C6-%E4%B8%89%E7%94%B2%E5%9F%BA%E5%90%A1%E5%95%B6 requires fine raw materials, making good use of the reaction, and paying attention to the technology of separation and extraction.
