1%2C4-%E4%BA%8C%E7%A2%98%E5%85%A8%E6%B0%9F%E4%B8%81%E7%83%B7, that is, 1,4-diiodoperfluorobutane, also known as octafluoro-1,4-diiodobutane. The physical properties of this substance have the following characteristics:
Its state is a liquid, under normal temperature and pressure, it looks like a flowing substance. Looking at its color, it is colorless and transparent, pure and free of impurities, visible through light, and has no appearance of turbidity.
When it comes to the boiling point, it is about 145-147 ° C. At this temperature limit, the substance changes from the liquid state to the gaseous state, and the molecular thermal motion intensifies, breaking free from the liquid phase. The value of the boiling point is affected by the intermolecular forces, and the specific combination of the intermolecular forces of this substance causes its boiling point to be in this range. The melting point of
is about -29 ° C. When the temperature drops to this point, the substance solidifies from liquid to solid, and the molecular arrangement tends to be ordered from disorder, forming a regular lattice structure. The density of
is also an important physical property, about 2.56 g/mL. This value shows that the mass of the substance contained in a unit volume reflects the degree of tight packing of molecules and the relative mass size.
Its solubility also has characteristics, and it is difficult to dissolve in water. Because water is a polar molecule, and the polarity of 1,4-diiodoperfluorobutane is weak, according to the principle of "similar miscibility", the two are difficult to miscible. However, in organic solvents, such as some halogenated hydrocarbons and ethers, there is a certain solubility, and it can be dispersed with each other due to the adaptation of intermolecular forces.
Vapor pressure is also a consideration. At a specific temperature, its vapor pressure characterizes the volatile tendency of substances. Although the data fluctuates with temperature, in general, it has a certain volatility, and in a closed space, gas-liquid equilibrium can be established.
Is the chemical properties of 1,4-diiodoperfluorobutane (4-diiodoperfluorobutane~ octafluoro-1,4-diiodobutane) stable?
1%2C4-%E4%BA%8C%E7%A2%98%E5%85%A8%E6%B0%9F%E4%B8%81%E7%83%B7, that is, 1,4-diiodoperfluorobutane, also known as octafluoro-1,4-diiodobutane. This physical property is quite stable.
Looking at its molecular structure, the carbon-fluorine bond energy is very high, and the fluorine atom surrounds the carbon chain, such as a shield, which makes it highly resistant to many chemical reagents. The electronegativity of the fluorine atom is extremely high, resulting in a large increase in the polarity of the carbon-fluorine bond, and the electron cloud is biased towards the fluorine atom, which makes the carbon nucleus difficult to be attacked by nucleophiles and difficult to initiate nucleophilic substitution reactions.
In common organic solvents, the solubility of 1,4-diiodoperfluorobutane is limited, because its molecular polarity is quite different from that And under general redox conditions, it is difficult to change significantly. Because of the stable distribution of chemical bonds within the molecule, it is difficult to be broken by common oxidative reducing agents.
However, under certain extreme conditions, such as high temperature, strong radiation or exposure to extremely strong nucleophiles, its stability will also be challenged. Under high temperature, molecular vibration intensifies, and chemical bonds can reach the breaking threshold, causing decomposition; strong nucleophiles such as lithium reagents may break through the fluorine atom barrier and interact with carbon nuclei to cause chemical reactions. But such extreme situations are rare in normal environments.
Overall, the chemical properties of 1,4-diiodoperfluorobutane are quite stable in the conventional chemical environment, and only under certain extreme conditions, its stability is affected, causing chemical reactions to occur.
