2-Hydroxyethylpyridine is a kind of organic compound. Its physical properties are quite characteristic, and I will describe them in detail.
Looking at its properties, at room temperature, it is mostly a colorless to light yellow liquid, with uniform and clear texture and no impurities visible to the naked eye. This liquid can be miscible with water and many organic solvents, just like water and emulsion. This property is due to the polar groups contained in its molecular structure, which makes it compatible with both polar and non-polar solvents.
When it comes to odor, the special smell it emits is not pungent and intolerable, but it is also unique. People with a little experience can know its unique smell when they smell it.
As for the density, compared with water, it is slightly different. The specific value varies slightly according to the experimental conditions, but it is generally within a specific range. The characteristics of this density are crucial in the separation and mixing of substances in chemical production and related experimental operations.
Its boiling point is also a key physical property. Under specific pressure conditions, when a certain temperature is reached, the substance will boil and vaporize. The existence of this boiling point becomes an important basis for separating the substance from other substances in distillation and purification processes.
In terms of melting point, although it is a liquid at room temperature, it will solidify when it drops to a specific low temperature. The exact value of the melting point provides an important reference for the identification of substances and the setting of storage conditions.
In addition, the refractive index of 2-hydroxyethylpyridine also has a fixed value, which plays an indispensable role in optical related fields and material purity detection. With its unique physical properties, 2-hydroxyethylpyridine plays an important role in many industries such as medicine, pesticides, dyes, etc.

The stability of the chemical properties of 2-hydroxyethylpyridine depends on many aspects.
In this compound, the hydroxyl group is connected to the pyridine ring, and the presence of the hydroxyl group endows it with a certain hydrophilicity. Hydroxyl groups can participate in many chemical reactions, such as esterification reactions, and can interact with acids to form corresponding esters. In this process, if the reaction conditions are severe, or its structure may change, which may affect its stability.
Furthermore, the pyridine ring is aromatic and has a certain stability. However, its nitrogen atom has lone pairs of electrons, which can react with protons or other electrophilic reagents. When encountering a strong acidic environment, the nitrogen atom of the pyridine ring may protonate, which in turn changes the electron cloud distribution of the molecule, which affects the overall stability.
Under generally mild conditions, 2-hydroxyethylpyridine may remain relatively stable. However, if it is exposed to extreme conditions such as high temperature, strong acid, and strong base, its chemical structure may be difficult to maintain stability. For example, in a strong base environment, the hydroxyl group may deprotonate and generate corresponding negative ions. This negative ion has high activity, or may trigger further reactions, resulting in changes in molecular structure.
In short, the chemical stability of 2-hydroxyethylpyridine is not absolute, but changes with external conditions. Under mild conditions, it is more stable, but under extreme conditions, it is prone to chemical changes, resulting in poor stability.

The preparation method of 2-hydroxyethylpyridine has several paths in the past. First, pyridine and ethylene oxide are used as starting materials, and the two interact under specific reaction conditions. This reaction process requires fine regulation of temperature, pressure and the use of catalysts. If the temperature is too high or too low, it can affect the reaction rate and the purity of the product; pressure is also a key factor, and the appropriate pressure can make the reaction proceed smoothly. The selected catalyst should be able to effectively promote the reaction of the two and improve the reaction efficiency.
Second, 2-chloroethanol and pyridine are used as raw materials, and the two react by nucleophilic substitution to form 2-hydroxyethylpyridine. However, in this reaction, it is necessary to pay attention to the choice of reaction solvent, and different solvents have a significant impact on the reaction. A suitable solvent can not only dissolve the reactants, but also promote the reaction and reduce the occurrence of side reactions. At the same time, the pH of the reaction process also needs to be properly controlled to prevent the decomposition of the reactants or the formation of unnecessary by-products.
Third, using 2-hydroxyethylamine and acronin as raw materials, it is obtained through a multi-step reaction. This path involves multi-step transformation, and the reaction conditions at each step need to be precisely grasped. From the ratio of starting materials to the temperature and time control of each step of the reaction, the yield and purity of the final product are all related. And the separation and purification steps after each step of the reaction should not be underestimated. Appropriate separation methods should be used to remove impurities and obtain pure 2-hydroxyethylpyridine.
All these methods have their own advantages and disadvantages. When actually preparing, when considering the purity, yield, availability of raw materials, cost and many other factors of the desired product, make a prudent choice.

The price of 2-hydroxyethylpyridine in the market is difficult to determine. Prices in the city often change due to various reasons, such as differences in origin, quality, time, and the state of demand.
In the past, some reference may be made to the market situation. If it is of good quality and comes from a good source, its price may be high when the demand is small; if the quality is flat, the source is wide and the supply is sufficient, and the price may be slightly inferior.
However, as recorded in "Tiangong Kaiwu", it is mostly related to the skills of Baigong and the method of making various things, and it does not involve the price of this thing in the market. Therefore, if you want to know the exact price, you can get a near-real price by consulting the current pharmaceutical stores, chemical material dealers, or studying the market on the platform of chemical product trading. The price of all kinds of goods in the market is like a current wave, which changes from time to time, and must not be adhered to.
