What are the physical properties of 1-Ethoxy-2,3-difluoro-4- (trans-4-pentylcyclohexyl) -benzene

1-Ethoxy-2,3-difluoro-4- (trans-4-pentylcyclohexyl) benzene, an organic compound, is widely used in the field of materials science, especially in liquid crystal materials. Its physical properties are crucial and relevant to practical use.

First of all, under normal temperature and pressure, it is mostly a clear and transparent liquid, just like a clear spring, pure and free. This form facilitates its use in many application scenarios, such as the manufacture of liquid crystal displays, which is convenient for uniform coating and filling.

When it comes to melting point, about a specific range, this value is of great significance to the thermal stability of materials. Like a threshold, when the temperature approaches the melting point, the molecular arrangement may change, which in turn affects the macroscopic properties of the material. The melting point of this compound ensures that it maintains a liquid crystal state in the normal operating temperature range, and the stability is good.

The boiling point is also a key property. Under a specific pressure, it boils when it reaches a certain temperature. The boiling point reflects the strength of the intermolecular force, and the boiling point is high when the force is strong. Its boiling point ensures that the material is not easy to volatilize in high temperature environments and maintains stable performance.

In terms of solubility, it has good solubility in common organic solvents such as toluene and chloroform. Like fish entering water, it can melt with organic solvents. This property is very useful in material preparation and processing. It can be prepared into a suitable solution by organic solvents to facilitate film formation or reaction.

The phase transition temperature is one of the core properties. Liquid crystal materials change with temperature and transition between different phases, including nematic phases and smectic phases. The optical and electrical properties of each phase state are significantly different. The specific phase transition temperature range allows the compound to adjust the molecular arrangement on demand in display technology to achieve image display.

Dielectric anisotropy cannot be ignored either. Under the action of an electric field, the molecular orientation changes, and the dielectric constant is anisotropic. This property allows liquid crystal molecules to be precisely arranged under the control of the electric field, which is the basis for liquid crystal displays to achieve image display. Appropriate dielectric anisotropy values ensure good display contrast and response speed.

Optical anisotropy is also critical. Due to the molecular structure, the absorption and propagation characteristics of light in different polarization directions are different. In liquid crystal displays, this property cooperates with dielectric anisotropy to achieve light modulation and make the screen present colorful images.

1-Ethoxy-2,3-difluoro-4- (trans-4-pentylcyclohexyl) benzene, what is the price of this product in the market? The price of the product in the market often varies for many reasons. Looking at the past, if it is in the market of chemical raw materials, its price is related to the trend of supply and demand, the difficulty of production, and the priority of quality.

If the state of supply and demand is balanced, the production is relatively easy, and the quality is ordinary, its price may be slightly cheaper. However, if the demand increases greatly, and it is not easy to make, and those who seek high quality will increase their price. In the past, if the quality of such chemical raw materials was moderate and the production and supply were slightly sufficient, the price per kilogram could be hundreds of gold.

However, the market situation is changeable, if the acquisition of raw materials changes, the process is innovated, and the price is also changed. Or because of the new technology, the cost of the system decreases, and the price also falls; or because the source material is scarce, there are many applicants, and the price rises.
