What are the physical properties of 1, 1, 2, 2, 3, 4, 4 - Nonafluorobutane - 1 - Sulphonyl Fluoride
1%2C1%2C2%2C2%2C3%2C3%2C4%2C4%2C4 - Nonafluorobutane - 1 - Sulphonyl Fluoride, the Chinese name is often nonafluorobutane - 1 - sulfonyl fluoride. The physical properties of this substance are special.
Its external color is often a liquid of yellow color to light color, and it is uniform to the ground. In other words, it can be clear and translucent, just like the clarity of water, but the color is slightly light. If the early morning light is in it,
Its boiling time is generally low. Under normal temperature, or about 60-70 degrees Celsius. Because there are many fluorine atoms in the molecule, the resistance of fluorine is low, so the molecular force is weak, so it is easy to melt and the boiling time is not high.
Melting also has characteristics, generally speaking, around -80 degrees Celsius. This low-temperature melting also depends on the special characteristics of molecules. The presence of polyfluorine atoms affects the density of the molecular arrangement, so that it can solidify at low temperatures.
In terms of density, the phase is large, 1.7 - 1.8 g/cm ³. Due to the large amount of fluorine atoms in the phase, and the increase in the amount of molecules in the molecular arrangement, the density is generally higher than that of compounds.
In terms of solubility, this substance has a certain solubility in solutions such as acetone, ether, etc. However, in water, the solubility is low. The molecules are non-soluble or weakly soluble, and the water is soluble. According to the principle of "similarity and dissolution", the two are mutually soluble.
The properties of the molecules are low, and they can be quickly destroyed under normal conditions. This is also because of its low boiling rate, the molecules are easy to escape into the air due to the surface of the liquid.
Therefore, 1%2C1%2C2%2C2%2C3%2C3%2C4%2C4%2C4 - Nonafluorobutane - 1 - Sulphonyl Fluoride The physical reason is that the molecules of its own characteristics are dense and dense, and the properties are mutual, showing the special characteristics of fluoride.
What are the chemical properties of 1, 1, 2, 2, 3, 4, 4 - Nonafluorobutane - 1 - Sulphonyl Fluoride
1%2C1%2C1%2C2%2C2%2C3%2C3%2C4%2C4%2C4 - Nonafluorobutane - 1 - Sulphonyl Fluoride, that is, nonafluorobutane - 1 - sulfonyl fluoride, the physical properties are as follows:
Its state is usually a colorless and transparent liquid, with high volatility, and it is easy to form gaseous escapes at room temperature and pressure. Looking at it, the pure one has no variegated impurities, and it is clear.
In terms of its boiling point, the value is quite low, about a few degrees Celsius to more than 20 degrees Celsius. Due to the weak intermolecular force, only a small amount of thermal energy is required to make the molecule break free and change from liquid to gaseous. The melting point of
is also in the relatively low temperature range, usually several tens of degrees Celsius below zero. This property makes the substance melt from solid to liquid at a lower temperature environment.
Its density is greater than that of common water, and it will naturally settle at the bottom when placed in water. The molecule contains many fluorine atoms, and the electronegativity of fluorine atoms is extremely high, resulting in strong molecular polarity, which affects its solubility. In organic solvents, such as halogenated hydrocarbons and ethers, it exhibits good solubility. Due to "similar miscibility", polar molecules are easily soluble in solvents with similar polar properties. However, the solubility in water is poor, and due to the strong hydrogen bonding between water molecules, it is difficult for the substance to form effective interactions with water molecules.
In terms of chemical stability, it is relatively high. The C-F bond formed by fluorine atoms has high energy and is not easy to break, making it difficult to react with common acids and bases, oxidants, reducing agents, etc. under normal conditions. However, under extreme conditions such as high temperature and strong catalysts, the C-F bond may also break, causing chemical reactions to occur. As a sulfonyl fluoride compound, the sulfonyl fluoride group has certain reactivity and can participate in reactions such as nucleophilic substitution. It can react with compounds containing active hydrogen, such as alcohols and amines, to generate corresponding sulfonates and sulfonamides. It can be used as an important intermediate in the field of organic synthesis to construct complex organic molecular structures.
1, 1, 2, 2, 3, 4, 4 - Nonafluorobutane - 1 - Sulphonyl Fluoride What are the precautions in the production process
1%2C1%2C2%2C2%2C3%2C3%2C4%2C4%2C4 - Nonafluorobutane - 1 - Sulphonyl Fluoride, that is, nonafluorobutane - 1 - sulfonyl fluoride, there are many things to pay attention to in the production process.
First, safety protection is very important. This substance is toxic and corrosive, and may pose a potential hazard to human health. During production, operators must wear professional protective clothing, protective gloves and goggles to prevent skin and eye contact. At the same time, effective gas masks are required to avoid inhalation of volatile gases. Because of volatile gases or irritation of the respiratory tract, even more serious health problems.
Second, the control of the production environment should not be underestimated. The production process should be carried out in a well-ventilated place, preferably in a closed space with a perfect ventilation system, and volatile gases should be discharged in time to prevent their accumulation in the air and reduce safety risks. In addition, the temperature and humidity should also be strictly controlled, because improper temperature and humidity may affect the reaction process and product quality. Generally speaking, the temperature and humidity should be precisely controlled according to the specific production process requirements.
Third, the storage of raw materials and products should be cautious. Raw materials and nonfluorobutane-1-sulfonyl fluoride products should be stored in a cool, dry and ventilated place, away from fire sources and oxidants. Due to their flammability and chemical activity, they can cause fire or explosion accidents in case of open flames, oxidants or violent reactions. Storage containers should also be made of corrosion-resistant materials, and ensure that they are well sealed to prevent leakage.
Fourth, the maintenance and cleaning of production equipment is essential. Due to the corrosive nature of the substance, it will cause a certain degree of erosion to the production equipment. Therefore, it is necessary to regularly check the equipment, detect and deal with corrosion, wear and tear and other problems in a timely manner, ensure the normal operation of the equipment, and avoid production accidents caused by equipment failures. After each production, the equipment should be thoroughly cleaned to prevent the residual substances from having adverse effects on the next production.
Finally, the production operation must be carried out in strict accordance with the standardized process. Operators need to undergo professional training and be familiar with the operation points and precautions of each production link. Any illegal operation, such as wrong feeding sequence, improper control of reaction time, etc., may lead to runaway reaction, affect product quality, and even cause safety accidents.
