2-% 284 - Hydroxypenyl%29pyridine is 2 - (4 - hydroxyphenyl) pyridine. The physical properties of this substance are described in detail below.
Its appearance is often crystalline, and when it is solid, it can be seen in a regular crystal shape. The crystalline color is mostly white to off-white, the texture is fine, and the appearance is pure.
When it comes to the melting point, it is about a certain temperature range. This melting point characteristic is the key to distinguish this substance from others. During the heating process, when a certain temperature is reached, the crystalline state of 2 - (4 - hydroxyphenyl) pyridine begins to melt into a liquid state. The value of this melting point is restricted by its molecular structure and interactions.
In terms of solubility, it shows different solubility in common organic solvents. In polar organic solvents, such as ethanol and acetone, it has a certain solubility. The polarity of ethanol interacts with some groups of 2- (4-hydroxyphenyl) pyridine, so that it can be dispersed in the ethanol system. However, in non-polar solvents, such as n-hexane, the solubility is very small, because the difference between molecular polarity and non-polar solvents is too large, and it is difficult to miscible with each other.
Furthermore, the density of this substance is also a specific value. The density reflects the mass per unit volume and is related to the degree of molecular packing. If the intermolecular force is strong and the packing is close, the density is relatively large; if it is not, it is relatively large.
In addition, the stability of 2- (4-hydroxyphenyl) pyridine is quite important. Under general environmental conditions, if there are no special factors to interfere, its chemical structure can remain relatively stable. However, under extreme conditions such as high temperature, strong acid, and strong base, the molecular structure may change, which affects its physical properties.
In summary, the physical properties of 2- (4-hydroxyphenyl) pyridine, such as appearance, melting point, solubility, density, and stability, are determined by its molecular composition and structure, and in practical applications and research, each property is interrelated and plays a role together.

To prepare 2- (4-hydroxyphenyl) pyridine, you can do it as follows.
First take an appropriate amount of 4-hydroxyphenylboronic acid and 2-bromopyridine as the starting materials. These two need to be assisted by palladium catalysts in the reaction system, such as tetra (triphenylphosphine) palladium. An appropriate amount of alkali, such as potassium carbonate, sodium carbonate, etc., needs to be added to create a suitable reaction environment. Then choose a suitable organic solvent, such as toluene, dioxane, etc., so that the raw materials can be evenly dispersed and the reaction can proceed smoothly. < Br >
During the reaction, the reactants are placed in a reaction vessel in an appropriate proportion, and an inert gas, such as nitrogen, is used to remove the oxygen in the system, because the oxygen often disturbs the reaction process. Then slowly heat up to a suitable temperature, usually around 100-120 ° C, and maintain this temperature to allow the reaction to proceed fully. During this period, stirring is required to make the reactants fully contact and speed up the reaction rate.
After the reaction is completed, the reaction liquid is cooled to room temperature. The products are separated and purified by common separation methods, such as column chromatography. First select a suitable eluent, and use the difference in the partition coefficient between the stationary phase and the mobile phase of different substances to separate the target product 2- (4-hydroxyphenyl) pyridine from impurities, and finally obtain a pure product. This preparation method requires attention to the precise control of the reaction conditions, the dosage ratio of raw materials, catalysts, bases, and the operation details of separation and purification, in order to achieve the ideal yield and purity.
