What are the physical properties of 4- [ (Trans, trans) -4 '-propyl [1,1' -bicyclohexyl] -4-yl] -1,2-dipfluorobenzene

4 - [ (Trans, trans) -4 '-propyl [1,1' -bicyclohexyl] -4-yl] -1,2 -difluorobenzene is an organic compound with unique physical properties. Let me tell you in detail.

This compound has a specific melting point, but the melting point value will vary depending on the purity of the sample and the measurement method. Generally speaking, those with high purity have relatively fixed and accurate melting points. Its melting point reflects the intermolecular force and lattice structure characteristics. The molecular arrangement is regular and the force is strong, and the melting point is higher.

Boiling point is also an important physical property. The boiling point is related to the size of the intermolecular attractive force, and the intermolecular force of this compound determines the energy required for boiling. The boiling point is affected by external pressure, and the boiling point is an inherent value under standard atmospheric pressure. When the pressure changes, the boiling point also changes accordingly.

In terms of solubility, the compound has good solubility in organic solvents such as toluene and dichloromethane. Because its molecular structure contains hydrophobic alkyl groups and aromatic rings, it has similar chemical properties to organic solvents. According to the principle of "similar miscibility", it is easily soluble in such solvents. However, the solubility in water is poor. Because water is a polar solvent, the intermolecular force with the compound is weak.

In appearance, it is usually a colorless transparent to yellowish clear liquid. The color is related to the purity, and the high purity is light in color. This appearance characteristic is convenient for preliminary judgment of its purity and quality in experiments and production.

Density is the mass per unit volume. The density of the compound is specific. In chemical production and experimental operations, density data is used to calculate mass, volume, and determine the location and distribution of substances in the mixed system.

In addition, the refractive index of the compound is fixed. The refractive index reflects the degree of change in the speed and direction of light propagation in it. It is related to the molecular structure and electron cloud distribution. It can be used to identify the purity and determine the type of compound.

The above physical properties are of great significance in the fields of organic synthesis and materials science. During synthesis, the reaction conditions and separation and purification of the product need to be controlled according to the melting point and boiling point. In material applications, the properties of solubility and density affect its compatibility and performance with other materials.

What is the chemical synthesis method of 4- [ (Trans, trans) -4 '-propyl [1,1' -bicyclohexyl] -4-yl] -1,2-dipfluorobenzene

To prepare 4- [ (trans, trans) -4 '-propyl [1,1' -bicyclohexyl] -4-yl] -1,2-difluorobenzene, the method is as follows:

Take the bicyclohexyl derivative first, which is the key starting material. Modify it in a specific way, and add propyl based on the 4 'position to obtain (trans, trans) -4' -propyl [1,1 '-bicyclohexyl] -4-one. This step requires delicate temperature control and selection of suitable reagents to make the reaction proceed as expected.

Then the ketonide is treated with a suitable reducing agent, such as sodium borohydride, and the corresponding alcohol is obtained through reduction reaction. In this step, the reaction conditions need to be carefully selected to ensure that the reduction is sufficient and the product is pure.

Furthermore, the obtained alcohol is introduced into the leaving group, such as using a halogenating agent to obtain a halogenate. The activity of this halogen is greatly increased, which lays the foundation for the subsequent reaction.

Another derivative of difluorobenzene is taken and treated with a strong base to form an active negative ion. This negative ion meets the above halogenate, and at a suitable solvent and temperature, through a nucleophilic substitution reaction, the two are connected to obtain 4- [ (trans, trans) -4 '-propyl [1,1' -bicyclohexyl] -4-yl] -1,2 -difluorobenzene. < Br >
The whole reaction process needs to protect the reaction environment and prevent impurities from invading, and the products in each step need to be purified and identified in detail to ensure that the synthesis is correct and the products reach the required purity.

4- [ (Trans, trans) -4 '-propyl [1,1' -bicyclohexyl] -4-yl] -1,2-dipfluorobenzene What is the price range in the market?

I look at what you are asking about "4 - [ (Trans, trans) -4 '-propyl [1,1' -bicyclohexyl] -4-yl] -1,2 -dipfluorobenzene", which is the name of an organic compound. However, it is difficult to determine the exact price range in the market. The price of the market is often affected by various factors, such as the difficulty of material sources, the simplicity of the preparation process, the supply and demand of the market, and even the trade area, the business strategy of the merchant.

If it is common sense, if the preparation of such fine organic compounds requires rare raw materials, the process is very complicated, and the market demand is small and the supply is limited, the price will be high. On the contrary, if the raw materials are easily available, the preparation is not difficult, and the market demand is stable, the price may be slightly lower.

However, without detailed market data, it is difficult to determine the upper and lower limits of the price. If you want to know the exact price, you can consult the merchants and chemical product suppliers in the chemical raw material trading market, or refer to the data recorded by the relevant chemical product price information platform to get a closer figure.
