The physical properties of 5-% green coke are rational, including density, viscosity, flow, ductility, and qualitative properties.
The density of the coke is also the amount of the material. The density of the green coke varies due to poor composition and processing. Its engineering is very important, such as road congestion, it is necessary to know the material density in order to calculate the dosage and estimate the weight.
Viscosity, that is, the force of the material to resist flow. The green often has stickiness, and it rises and falls. This property affects the construction and performance. For example, in summer, the green viscosity decreases, and the road is easy to shape; in winter, it is low, and the viscosity rises, and it is easy to crack.
The phase of flow and viscosity refers to the degree to which the material is easy to flow under external force. Green is subjected to or external force, and the flow property is reduced. Construction, it needs to be suitable for flow performance, and it needs to be filled evenly.
Ductile, the material is shaped by tensile energy without cracking. The green coke has certain ductility, which can withstand road load and environmental extension. Good ductility guarantees the quality of the material's life.
Qualitative, that is, the material is subject to damage, and the quality of the property is maintained. At high temperatures, if the quality of the green coke is not good, it is easy to change the shape; if it is low, if the quality of the green coke is poor, it is easy to embrittle and crack. Therefore, it is necessary to have good quality and different conditions.
Where this physical property affects each other, in multiple fields such as road construction and waterproofing engineering, the performance and lifespan of 5-% green [c] coke must be considered.

5-% cyanomercury and [c] quinoline is one of the organic mercury compounds. Its chemical properties are unique, with the following ends:
- ** Stability **: 5-% cyanomercury and [c] quinoline under normal conditions, the stability is quite high. In case of hot topics, open flames or strong oxidants, it is easy to cause chemical reactions and cause structural damage. This is because high temperature, open flames or strong oxidants can provide enough energy to cause the chemical bonds in the molecule to break, and then decompose or other chemical reactions occur.
- ** Solubility **: The substance is slightly soluble in water and has better solubility in organic solvents such as ethanol and ether. This is because the 5-% cyanomercury and [c] quinoline molecule has both polar and non-polar parts, and the force between it and the organic solvent molecule is stronger, so it has a greater solubility in organic solvents.
- ** Reactivity **: The mercury atom in the molecule interacts with the cyano group and the quinoline ring, causing it to have a certain reactivity. Under specific conditions, the mercury atom can participate in the substitution reaction, and its empty orbit can accept other atoms or group electron pairs to form new compounds. In addition, the cyano group can also participate in many reactions, such as hydrolysis. Under acidic or basic conditions, the cyano group can be gradually converted into other functional groups such as carboxyl groups. < Br > - ** Coordination ability **: 5% cyanomercury and [c] quinoline contain nitrogen, mercury and other atoms, which can be used as ligands to coordinate with metal ions to form complexes. The nitrogen atom on the quinoline ring has lone pair electrons, and the mercury atom can also provide empty orbitals, which can be combined with other metal ions through coordination bonds. This property may have applications in the fields of materials science and catalysis.

The common synthesis method of 5-% [C] azole has the following ends:
First, the raw materials of aromatic aldehyde, ethyl acetoacetate, carbonate and chlorination are mixed in a suitable solution. This way is through the ingenious reaction of multiple components, such as combination and reduction. The molecular skeleton of 5-% [C] azole. Its dissolution is often based on factors such as alcohol, ether, etc., which have good solubility and inert properties. The degree of addition, the activity of the reactants, and the solution of the reactants.
Second, with a specific nitrogen-containing precursor, and a specific phase, the co-reaction can be achieved in the context of the chemical environment. The chemical element can activate the anti-reaction compound and promote the migration and rearrangement of its offspring. The complex, such as carbonate, oxidation, etc., depends on the demand. This complex, which is formed by the chemical combination, can be used as a highly efficient catalytic activity center, leading the reaction towards the direction of generating 5-% [C] azole, and has an important control effect on the properties of the reverse domain and vertical transformation.
Third, the anti-addition strategy is used. Addition is generated in the presence of catalysts in the presence of nitrogen-containing or three-dimensional compounds, in the presence of nitrogen-containing and chemical activity. Catalysis can be used to reduce the activation energy of gold complexes, or specific small molecules, which can be used to reduce the addition of the original generation. In this way, one-step multi-processing can be done to efficiently synthesize the target compounds, and the integration of the target materials is easy to control.
All these methods have their own advantages and disadvantages. Only by balancing the requirements of the raw materials, the target materials and the target materials can the ideal synthesis effect be obtained.
