What are the physical properties of Perfluoro (2,5-Dimethyl-3,6-Dioxananoy) Fluoride
Perfluorinated (2,5-dimethyl-3,6-dioxanonyl) fluorides have unique physical properties. In appearance, this substance is often colorless and transparent at room temperature and pressure, resembling clear water, but it also contains different chemical characteristics. Its phase state is mostly in the form of a liquid, with good fluidity, like a smart flow, and can be easily transferred between containers.
Looking at its boiling point, it is in a specific temperature range. Due to the existence of perfluorinated groups in the molecular structure, the intermolecular force takes a special form, so the boiling point is higher than that of ordinary organic compounds, about [X] ° C. This boiling point characteristic is of key significance in the process of separation, purification and application.
As for the melting point, it also has its own unique features. Due to the influence of specific carbon-fluorine bonds and dioxane heterocyclic structures in the molecule, the melting point is roughly at [Y] ° C. This melting point value allows the substance to maintain liquid stability within a specific temperature range, providing convenient conditions for many chemical reactions and industrial applications.
In terms of density, due to the large number of fluorine atoms in the molecule, the relative atomic mass of fluorine atoms is larger and the atomic radius is smaller, so the density of this substance is larger than that of common organic solvents, about [Z] g/cm ³. This density characteristic allows the substance to be separated from other substances with different densities by physical methods in a mixed system.
In terms of solubility, because it is a perfluorinated compound, it has strong hydrophobicity and is difficult to dissolve in polar solvents such as water. However, in some non-polar organic solvents, it shows good solubility and can be miscible with perfluorinated hydrocarbon solvents. This difference in solubility is widely used in chemical synthesis, extraction and other fields, which can be used to achieve effective separation and purification of substances.
What are the chemical properties of Perfluoro (2,5-Dimethyl-3,6-Dioxananoy) Fluoride
Perfluoro (2,5 - Dimethyl - 3,6 - Dioxananoy) Fluoride is a fluorine-containing organic compound. Its chemical properties are unique. Because its molecular structure contains multiple fluorine atoms, fluorine atoms have high electronegativity, which makes the compound exhibit special physical and chemical properties.
In this compound, the perfluoroalkyl part endows it with excellent chemical stability. The covalent bond between fluorine atoms and carbon atoms is extremely strong and can resist the attack of many chemical reagents. Therefore, under many chemical reaction conditions, this compound can remain relatively stable and is not prone to general substitution, addition and other reactions.
Furthermore, due to the presence of fluorine atoms, the surface energy of the compound is very low, and it has good hydrophobicity and oleophobic properties. This property makes it show broad application prospects in the field of materials science, such as the preparation of waterproof and oil-proof special coating materials.
From the perspective of reactivity, although the overall chemical stability is high, the acyl fluoride functional group (-COF) in the molecule still has a certain activity. The acyl fluoride group easily reacts with nucleophiles, such as with alcohols to form esters, and with amines to form amides. This reactivity provides the possibility for its use in organic synthesis to construct complex molecular structures.
In addition, the solubility of the compound is also affected by its structure. Due to the presence of perfluoroalkyl groups, its solubility in organic solvents is different from that of ordinary organic compounds, and it may have better solubility in some fluorine-containing organic solvents or some non-polar organic solvents.
Perfluoro (2,5 - Dimethyl - 3,6 - Dioxananoy) Fluoride has potential applications in the fields of materials science and organic synthesis due to its unique chemical structure, showing chemical properties such as stability, low surface energy and specific reactivity.
What is the production method of Perfluoro (2,5-Dimethyl-3,6-Dioxananoy) Fluoride?
The preparation of perfluorinated (2,5-dimethyl-3,6-dioxanonyl) fluorine requires several delicate chemical reaction steps.
The first step is to introduce halogen atoms through a halogenation reaction, usually starting materials containing appropriate substituents, mostly ethers or alcohols containing specific alkyl groups. This halogenation reaction requires the selection of suitable halogenating reagents, such as halogenated phosphorus or halogenated sulfoxide, etc. At appropriate temperatures and reaction times, specific positions in the raw material molecules are replaced by halogen atoms to form halogenated intermediates.
The second step is to react the halogenated intermediate with a fluorine-containing reagent. This is a key step, which aims to gradually replace other halogen atoms or specific groups with fluorine atoms. Commonly used fluorinated reagents include potassium fluoride, antimony trifluoride, etc. The reaction is often carried out in polar aprotic solvents, such as dimethyl sulfoxide or N, N-dimethylformamide. By precisely controlling the reaction conditions, such as temperature, pressure and the proportion of reactants, the fluorination reaction occurs efficiently and selectively, thereby constructing a perfluorinated carbon skeleton structure.
Furthermore, the obtained preliminary fluorinated product needs to be acylated to introduce the desired acyl moiety. In the presence of a catalyst, a suitable acylating agent, such as an acyl halide or an acid anhydride, is often used to react with the fluorinated product to form an acyl structure at the end of the molecule.
At the end of the process, the product is purified and refined. Separation techniques such as distillation, recrystallization, and column chromatography are used to remove unreacted raw materials, by-products, and impurities to obtain high-purity perfluorinated (2,5-dimethyl-3,6-dioxanonyl) fluorine. Each step requires precise control of the conditions to achieve efficient and high-quality preparation results.
What are the precautions for the use of Perfluoro (2,5-Dimethyl-3,6-Dioxananoy) Fluoride

Users must wear suitable protective equipment, such as protective clothing, protective gloves, anti-goggles, etc., to protect against possible damage. And the operation is suitable for a well-ventilated environment, or in a fume hood to prevent its volatile gases from being inhaled by the human body.
In addition, its chemical properties are unique, and it must be kept away from fire sources, heat sources and oxidants when storing. Because of its activity, it is exposed to heat, open flames or oxidants, or causes violent chemical reactions, causing the risk of combustion and explosion. Store in a dry, cool and ventilated place, and the temperature and humidity should also be properly controlled.
During operation, the established procedures should also be strictly followed. Weighing accurately and transferring carefully, do not spill the substance. Once accidentally spilled, it needs to be properly cleaned immediately according to regulations to prevent pollution to the environment.
