What are the physical properties of Hexanoyl Fluoride, 2,2,3,3,4,4,5,5,6,6-Undecafluoro-
2%2C2%2C3%2C3%2C4%2C4%2C5%2C5%2C6%2C6%2C6-undecafluorohexyl fluoride is a genus of organic fluorine compounds. Its physical properties are unique, let me come one by one.
Looking at its properties, it is mostly colorless to light yellow liquids under normal conditions. Due to the introduction of fluorine atoms, the intermolecular forces and electron cloud distribution are greatly changed, resulting in its appearance different from common hydrocarbons.
When it comes to boiling points, due to the high electronegativity of many fluorine atoms, strong dipole-dipole forces are formed between molecules, and the boiling point of hexyl fluoride is lower than that of ordinary hexyl fluoride, about 50-70 ° C. And it has low surface tension. Because the outer electron cloud of fluorine atoms is tight, it interacts weakly with other molecules, so that the molecules on the liquid surface are subject to small inward tension and easy to spread.
In terms of solubility, due to molecular polarity and hydrophobicity of fluorocarbon chains, it is slightly soluble in water, but soluble in most organic solvents, such as dichloromethane, chloroform, ether, etc. This characteristic is derived from the principle of similar phase dissolution, and the van der Waals force between the organic solvent molecule and the fluorocarbon chain of the compound is conducive to dissolution.
The density is greater than that of water, the fluorine atom has a large mass and a small atomic radius, the intramolecular space is closely arranged, and the unit volume mass increases, causing it to sink in water.
Excellent volatility. Due to the weakening of the intermolecular force of fluorine atoms, the thermal motion of molecules can easily overcome the force and escape from the liquid surface. It can evaporate
In summary, the unique physical properties of 2%2C2%2C3%2C3%2C4%2C4%2C5%2C5%2C6%2C6%2C6-undecafluorohexyl fluoride are determined by the properties of fluorine atoms, and are widely used in organic synthesis, materials science and other fields.
What are the chemical properties of Hexanoyl Fluoride, 2,2,3,3,4,4,5,5,6,6-Undecafluoro-
2%2C2%2C3%2C3%2C4%2C4%2C5%2C5%2C6%2C6%2C6-undecafluorohexyl fluoride, which is also an organic fluorine compound. Its chemical properties are quite unique, and the following is detailed by Jun.
First, it has strong chemical activity. The acid fluoride group is active and easily reacts with many nucleophilic reagents. In case of water, it quickly hydrolyzes to generate corresponding acids and hydrogen fluoride. This hydrolysis reaction is violent. Because hydrogen fluoride is extremely corrosive, extreme caution is required when handling this substance.
Second, due to the large number of fluorine atoms in the molecule, it has high stability. The electronegativity of fluorine atoms is extremely high, and the carbon-fluorine bond energy is quite large, which makes the compound able to withstand harsh conditions such as high temperature, strong oxidizing agents and reducing agents. In many chemical reactions, the carbon-fluorine skeleton of this substance is usually stable and cannot be easily destroyed.
Third, good surface activity. The presence of a large number of fluorine atoms makes the surface energy of the molecule extremely low, so it can significantly reduce the surface tension in organic solvents or water, showing good surface activity. This property makes it potentially used in coatings, lubricants, water repellents and other fields.
Fourth, special solubility. Because the molecule has both the hydrophobicity of the fluorocarbon chain and the polarity of the acyl fluoride group, its solubility in organic solvents varies depending on the type of solvent. Generally speaking, the solubility of polar organic solvents is better than that of non-polar organic solvents.
In short, 2%2C2%2C3%2C3%2C4%2C4%2C5%2C5%2C6%2C6%2C6-undecafluorohexanoyl fluoride exhibits active and stable coexistence, good surface activity and special solubility due to its unique chemical structure, which shows important application value in chemical industry, materials and other fields.
What is the production method of Hexanoyl Fluoride, 2,2,3,3,4,4,5,5,6,6-Undecafluoro-?
The method for preparing 2,2,3,3,4,4,5,5,6,6,6-undecafluorohexyl fluoride is described below.
Often fluoroolefins are used as starting materials. If a suitable perfluoroolefin is selected, it will react with carbon monoxide and hydrogen fluoride under a specific catalytic system. This catalytic system or metal-containing catalysts, complexes of precious metals such as palladium and rhodium, play a key catalytic role in the reaction, which can reduce the activation energy of the reaction and promote the reaction to occur under milder conditions.
When reacting, the reaction temperature and pressure must be strictly controlled. The temperature may be maintained within a certain range, such as between 30 ° C and 80 ° C, the temperature is too high or the side reactions increase, which affects the purity of the product; the pressure must also be appropriate, about 1-5 MPa, and the appropriate pressure is conducive to the reaction to generate the target product.
During the reaction process, the ratio of materials is also extremely important. The ratio of carbon monoxide to fluoroolefins and hydrogen fluoride needs to be precisely adjusted to achieve the best reaction effect and product yield. Usually, the appropriate ratio can be determined according to experimental exploration and theoretical calculations.
After the reaction is completed, the product needs to be separated and purified. First, the distillation method is used to take advantage of the difference in the boiling point of each substance to initially separate the fraction containing the target product. Then, extraction, column chromatography and other means are used to further purify to obtain high-purity 2, 2, 3, 3, 4, 4, 5, 5, 6, 6-undecafluorohexyl fluoride. The whole preparation process requires attention to the precise control of reaction conditions and the standard operation of each step to ensure the quality and yield of the product.
Hexanoyl Fluoride, 2,2,3,3,4,4,5,5,6,6-Undecafluoro- what are the precautions when using
Hexanoyl fluoride, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6 - undecafluoro - that is, perfluorohexyl fluoride. When using this product, pay attention to the following things:
First, this product is highly corrosive and can cause serious burns and injuries when it comes into contact with the skin, eyes or inhalation of its volatile gases. When operating, be sure to wear complete protective equipment, such as protective gloves, protective glasses, gas masks and protective clothing, to avoid direct contact.
Second, perfluorohexyl fluoride is chemically active and easy to react with many substances. During use, keep away from fire sources, heat sources and oxidants to prevent dangerous accidents such as combustion and explosion. When storing, it should also be stored separately in a cool, dry and well-ventilated place, and away from incompatible substances.
Third, because of its strong volatility, use should be carried out in a fume hood to ensure smooth ventilation in the workplace, timely discharge of volatile gases, to prevent the accumulation of harmful gases and endanger personal safety.
Fourth, before and after use, it is necessary to strictly check and clean the relevant equipment and appliances to avoid adverse reactions caused by mixing impurities. The operation process should follow precise procedures and control the reaction conditions, such as temperature, pressure, reaction time, etc., to ensure the smooth progress of experiments or production.
Fifth, if you accidentally come into contact with this object, emergency measures should be taken immediately. If it comes into contact with the skin, it is necessary to quickly rinse with a large amount of running water; if it splashes into the eyes, it is necessary to immediately rinse with a large amount of water and seek medical attention in time; if inhaled, it should be moved to a fresh place as soon as possible and seek medical attention.
