2 - (2 - hydroxyethyl) pyridine, its physical properties are as follows:
This substance is mostly liquid at room temperature, and it looks clear and translucent, like a clear spring. Its smell is special, and its smell has a unique smell. It is neither fragrant nor pungent, but unique and difficult to describe.
When it comes to solubility, it can show a good state of integration in water and many polar organic solvents. If in water, it can be quietly dispersed, just like salt dissolves naturally in water, forming a uniform mixture. This is because the hydroxyl groups contained in the molecules can form hydrogen bonds with water molecules, attracting and blending with each other. The boiling point of
is quite high. When it is heated, the temperature needs to rise to a certain extent before it can boil into a gaseous state. This characteristic indicates that the intermolecular force is strong, and more energy needs to be supplied to change its state. The melting point of

The above physical properties are all key elements for the understanding and application of 2- (2-hydroxyethyl) pyridine, and are of great significance for its use and research in many fields such as chemical industry and medicine.

2- (2-hydroxyethyl) pyridine is a class of organic compounds. Its properties are colorless to light yellow liquid, with a slightly specific odor and certain hygroscopicity.
In terms of solubility, this compound can be miscible with many organic solvents such as water, alcohol, ether, etc. This property makes it an excellent solvent or reaction medium in many chemical reactions and industrial processes.
In terms of chemical activity, the pyridine ring and hydroxyethyl group of 2- (2-hydroxyethyl) pyridine give their unique reactivity. Pyridine ring is rich in electrons and is easily attacked by electrophilic reagents, and can undergo electrophilic substitution reactions such as halogenation, nitrification, and sulfonation. The hydroxyl group in the hydroxyethyl group not only has the typical properties of alcohols, but also participates in esterification and etherification reactions, and because it is connected to the pyridine ring, the activity of the hydroxyl group is also affected by the electronic effect.

2-%282-Hydroxyethyl%29pyridine is 2- (2-hydroxyethyl) pyridine, and its synthesis method is as follows:
First, 2-methylpyridine is used as the starting material. First, 2-methylpyridine and paraformaldehyde are reacted under the action of a specific catalyst under suitable temperature and pressure conditions. This reaction is a nucleophilic substitution reaction mechanism. The methyl group of 2-methylpyridine is affected by the catalyst, and its activity is enhanced. It attacks the carbonyl carbon of paraformaldehyde. After hydrolysis, 2- (2-hydroxyethyl) pyridine can be obtained. This route raw material is relatively common, and the reaction conditions are relatively easy to control, but the stability and dosage of paraformaldehyde should be paid attention to when using it. < Br >
Second, pyridine and ethylene oxide are used as raw materials. The nitrogen atom of pyridine is nucleophilic, which can attack the epoxy bond of ethylene oxide and cause a ring-opening reaction. The reaction can speed up the reaction rate under the action of basic catalyst. Due to the high activity of ethylene oxide, the reaction needs to precisely control the temperature and reaction time, otherwise it is easy to produce side reactions and affect the purity and yield of the product. This method has high atomic utilization and is in line with the concept of green chemistry.
Third, 2-pyridine methanol is used as raw material. Under the action of a suitable oxidant, 2-pyridyl methanol is first oxidized to 2-pyridyl formaldehyde, and then a hydroxyaldehyde condensation reaction occurs with formaldehyde under alkali catalysis to generate 2- (2-hydroxyethyl) pyridine. In this process, the oxidation step needs to select a suitable oxidant and reaction conditions to ensure the selective oxidation of aldehyde groups and avoid excessive oxidation to carboxyl groups. The hydroxyaldehyde condensation step should pay attention to the type and dosage of bases, as well as the reaction temperature to prevent side reactions from occurring.

2 - (2-hydroxyethyl) pyridine is also an organic compound. When storing and transporting, many matters need to be paid attention to.
First, the compound should be stored in a cool and ventilated warehouse. Due to high temperature or changes in its properties, it is dangerous. Second, it is necessary to keep away from fires and heat sources. This is because the substance may be flammable, and it is easy to cause combustion accidents in case of open flames and hot topics. Third, it should be stored separately from oxidants and acids, and should not be mixed. Chemical reactions between oxidants and acids or with 2 - (2-hydroxyethyl) pyridine can cause dangerous conditions. Fourth, the warehouse needs to be equipped with suitable materials to contain leaks, so as to prevent accidental leakage and deal with them in time to avoid polluting the environment or causing other hazards.
As for transportation, first, the transportation vehicle must be thoroughly cleaned and disinfected, and there must be no residue that reacts with 2 - (2 - hydroxyethyl) pyridine. Second, during transportation, ensure that the container does not leak, collapse, fall, or damage. Damage to the container can cause material leakage, which poses a safety hazard. Third, when transporting, follow the specified route and do not stop in densely populated areas and open flames. This is to prevent serious consequences in the event of leakage in crowded or fire-source areas. Fourth, during transportation, it should be protected from sun exposure, rain, and high temperature. External environmental factors may affect the stability of the substance, which in turn endangers the safety of transportation.
Therefore, when storing and transporting 2- (2-hydroxyethyl) pyridine, follow the above precautions to ensure safety.
