Looking at its appearance, it is usually in a crystalline solid state, dense and has a regular lattice structure, which is due to the orderly arrangement of intermolecular forces. The color may be white to light yellow, and the purity of the color is often related to the purity. Impurities affect its color. If the purity is high, the color will be light. < Br >
In terms of melting point, the compound has a specific melting point range, or between 150 and 160 ° C. At this temperature, the molecule obtains enough energy, the lattice structure disintegrates, and the solid state turns to a liquid state. Melting point determination is a common means to identify purity and material properties. When impurities are present in the compound, the melting point may drop and the melting range becomes wider.
Solubility is also an important physical property. In organic solvents, such as ethanol, acetone, and chloroform, it exhibits good solubility. Due to the similar principle of miscibility, the force between organic molecules and organic solvent molecules is strong. However, in water, due to the dominant structure of hydrophobic groups, the solubility is poor. This property is crucial for the separation, purification, and solution preparation of compounds. < Br >
The density is related to the unit volume mass, and its density may be between 1.2 and 1.3 g/cm ³. Although it is not extremely heavy, it is higher than that of common organic solvents. Density determination helps to determine the proportion of liquid mixture components and quantitative analysis of compounds.
Volatility is weak, and it is not easy to evaporate under normal conditions. Due to strong intermolecular forces, it is difficult for molecules to break free and enter the gas phase. This property makes it stable during storage and use, and it is not easy to lose or change concentration due to volatilization.

The methods for synthesizing ethylmethyl 2,6-dimethyl-4- (3-nitrophenyl) -1,4-dihydropyridine-3,5-dicarboxylate are generally as follows.
One is based on the Hantzsch reaction. This reaction is a classic method, usually using ethyl acetoacetate, 3-nitrobenzaldehyde and ammonia or ammonium salt as raw materials, in an alcohol solvent, heated and refluxed. During this process, the aldehyde and two molecules of β-ketoate are first condensed, and then cyclized with ammonia to obtain the target product. This process requires attention to the control of reaction temperature, raw material ratio and reaction time. If the temperature is too low, the reaction will be slow; if it is too high, the side reaction will occur. Improper proportion of raw materials also affects the yield.
Second, microwave-assisted synthesis method. Under microwave radiation, the reaction process is accelerated. Compared with traditional heating, microwaves can make molecules vibrate and collide rapidly, so that the reaction system can quickly reach the required temperature and be heated evenly. In this way, the reaction time is greatly shortened and the yield may be improved. However, special microwave equipment is required, which requires high precision regulation of reaction conditions.
Third, metal catalytic synthesis method. Specific metal catalysts can be selected, such as some transition metal complexes. Metal catalysts can reduce the activation energy of the reaction and promote the reaction. It can change the reaction path and make the reaction more efficient. However, it is crucial to choose the appropriate catalyst, control the amount of catalyst and the pH, temperature and other conditions of the reaction environment. Due to the activity and selectivity of the catalyst, the purity and yield of the product are greatly affected.
These three synthesis methods have their own advantages and disadvantages. The Hantzsch reaction is classic and mature, but it takes time or time; the microwave-assisted synthesis is efficient and fast, and the equipment requirements are high; the metal catalysis has the advantage of selectivity, and the condition control is complicated. When synthesizing, it is necessary to choose the appropriate method according to the actual situation, such as the availability of raw materials, equipment conditions, product requirements, etc.
