First, the appearance. Under normal temperature and pressure, it is often white to light yellow crystalline powder, just like finely crushed jade chips, with fine texture. This form is conducive to storage and transportation, and is easy to handle in subsequent processing.

The melting point is also a key property, about [X] ° C. When the temperature rises to this point, the substance will gradually melt from a solid state to a liquid state like ice and snow in the warm sun. The determination of the melting point provides an important basis for the determination of its purity. The melting point of pure products is relatively fixed, and if it contains impurities, the melting point will shift.

In terms of boiling point, it is about [X] ° C. At this temperature, the compound turns into a gaseous state and dissipates. The boiling point is affected by the intermolecular force. Due to the specific structure, the intermolecular force of this compound is moderate, so the boiling point is within a certain range.

The solubility cannot be ignored. In organic solvents such as dichloromethane and chloroform, it is like a salt integrated into water, which has good solubility and can be uniformly dispersed to form a solution. However, in water, the solubility is poor, because the proportion of hydrophobic groups in the molecular structure is large, and the affinity with water molecules is weak. < Br >
The density is about [X] g/cm ³, which is similar to the density of common organic solvents. Density is of great significance in operations such as separation and purification. With the help of density differences, it can be separated by methods such as extraction.

In addition, the compound has certain stability, and the structure is not easy to change under conventional environmental conditions. However, in case of extreme conditions such as strong acid, strong alkali or high temperature, the structure will be damaged and chemical reactions will occur, resulting in changes in properties.
