What is the chemical composition of 2,2 '-Ethene-1,2-Diylbis (5-Nitrobenzenesulfonic Acid)?
2%2C2%27-Ethene-1%2C2-Diylbis%285-Nitrobenzenesulfonic Acid% 29 is the English name of an organic compound, and its corresponding Chinese name is 2,2 '-ethylene-1,2-diyl bis (5-nitrobenzenesulfonic acid). The chemical composition of this compound can be analyzed as follows:
- ** Main structure **: contains vinyl (ethene-1,2-diyl), which is an unsaturated hydrocarbon structure. It consists of two carbon atoms connected by a double bond, i.e. -CH = CH-, which provides unsaturation and a specific spatial configuration for the whole molecule.
- ** Benzene ring substituent **: At both ends of the vinyl group, a benzene sulfonic acid group (5-nitrobenzenesulfonic acid) is connected. Benzene sulfonic acid is basically derived from the benzene ring. The 5-position on the benzene ring (counted as the 1-position of the carbon connected to the vinyl group) is replaced by the nitro group (-NO 2). At the same time, the benzene ring is also connected with the sulfonic acid group (-SO 🥰 H). The sulfonic acid group gives the compound a certain water solubility and acidity, while the nitro group affects the electron cloud distribution, chemical activity and stability of the molecule.
- ** Overall Composition **: In general, the chemical formula of this compound can be roughly written as C H N O S ³, which reflects that the molecule contains 14 carbon atoms, 10 hydrogen atoms, 2 nitrogen atoms, 10 oxygen atoms and 2 sulfur atoms. Its structure contains not only unsaturated structures such as carbon-carbon double bonds and benzene rings, but also polar functional groups such as nitro and sulfonic acid groups. This structure makes the compound have unique physical and chemical properties and may have specific uses in organic synthesis, materials science and other fields.
What are the physical properties of 2,2 '-Ethene-1,2-Diylbis (5-Nitrobenzenesulfonic Acid)?
2%2C2%27-Ethene-1%2C2-Diylbis%285-Nitrobenzenesulfonic Acid% 29, this is an organic compound, and its physical properties are as follows:
In terms of its morphology, it often takes the form of a solid state. In terms of color state, or white to light yellow powder, it is fine and uniform, which is due to the molecular structure and aggregation state.
When it comes to solubility, it can show certain solubility in water. The cover has a sulfonic acid group in its molecule, which is a hydrophilic group and can form hydrogen bonds with water molecules, so it has a certain solubility in polar water environment; however, in non-polar organic solvents, such as alkanes, the solubility is very small, because the overall polarity of the molecule does not match the non-polar solvent.
The melting boiling point is also an important property. Due to the existence of various interactions between molecules, such as electrostatic interactions, hydrogen bonds, etc., it has a high melting point. Strong energy is required to destroy the intermolecular force and make the substance change from solid to liquid. However, the exact melting and boiling point value is still related to factors such as material purity.
In addition, density is also one of the considerations. Its density may be slightly higher than that of water. Due to the fact that the molecular composition contains relatively large groups such as benzene ring, nitro group and sulfonic acid group, the mass per unit volume increases. The stability of this compound to light and heat is also affected by its molecular structure. The conjugation of nitro and benzene ring makes the molecular electron cloud distribution have a specific pattern, and the structure can be maintained in a certain degree of light and temperature range. However, under high temperature, strong light, or due to the intensification of chemical bond vibration, the structure changes.

2%2C2%27-Ethene-1%2C2-Diylbis%285-Nitrobenzenesulfonic Acid% 29 is 2,2 '-ethylene-1,2-diyl bis (5-nitrobenzenesulfonic acid), the preparation method of this compound is as follows:
To prepare 2,2' -ethylene-1,2-diyl bis (5-nitrobenzenesulfonic acid), benzenesulfonic acid can be obtained by reacting with ethylene and nitrogenation reagents. First take an appropriate amount of benzenesulfonic acid and place it in a suitable reaction vessel. Benzenesulfonic acid is an aromatic compound with a sulfonic acid group, which is more active in nature.
Then pass into ethylene gas. Ethylene is an unsaturated hydrocarbon with a double bond structure and high reactivity. When introducing ethylene, pay attention to the regulation of reaction temperature and pressure. Generally speaking, the temperature should be maintained in a moderate range, about tens of degrees Celsius, and the pressure should be appropriate to ensure the smooth progress of the reaction. After
, add a nitrogenation reagent. Common nitrogenation reagents such as concentrated nitric acid and concentrated sulfuric acid mixed acid. In this reaction, concentrated sulfuric acid can not only act as a dehydrating agent, but also promote the reaction to move in the direction of product formation, and can enhance the nitrification ability of nitric acid. Concentrated nitric acid is a donor of nitro groups, which can introduce nitro groups into the benzene ring of benzenesulfonic acid. During the
reaction, the benzene ring of benzenesulfonic acid is affected by the ethylene double bond, and the electron cloud distribution changes, making it easier for nitro groups to replace hydrogen atoms at specific The ethylene double bond is opened, connected to the benzenesulfonic acid molecule, and finally formed 2,2 '-ethylene-1,2-diyl bis (5-nitrobenzenesulfonic acid).
After the reaction is completed, it needs to go through the steps of separation and purification. The pure 2,2' -ethylene-1,2-diyl bis (5-nitrobenzenesulfonic acid) product can be obtained by extraction, distillation, and recrystallization using methods such as extraction, distillation, and recrystallization.
What are the precautions for the transportation and storage of 2,2 '-Ethene-1,2-Diylbis (5-Nitrobenzenesulfonic Acid)?
2%2C2%27-Ethene-1%2C2-Diylbis%285-Nitrobenzenesulfonic Acid% 29 is 2,2 '-ethylene-1,2-diylbis (5-nitrobenzenesulfonic acid). When transporting and storing this product, there are many precautions to be taken.
Its chemical properties are relatively active, and it may be dangerous when exposed to heat or contact with certain substances. When transporting, ensure that the container is well sealed to prevent leakage. The selected transportation vehicle should have appropriate temperature control and shock protection measures, as it is sensitive to temperature fluctuations and vibration. If the temperature is too high, it may cause decomposition or other chemical reactions. Excessive vibration may also cause damage to the package, resulting in material leakage.
Store in a cool, dry and well-ventilated place. Keep away from fire and heat sources to prevent direct sunlight. It should be stored separately from oxidants, reducing agents, alkalis, etc., and should not be mixed. Because of its contact with these substances, severe chemical reactions may occur, resulting in serious consequences such as fire and explosion.
The humidity of the storage environment also needs to be strictly controlled. Excessive humidity may cause substances to be damp and deteriorate, affecting their chemical stability. In addition, the storage area should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment for emergencies. Staff should pack and unload lightly when handling to prevent damage to packaging and containers.
Only by strictly following the above transportation and storage precautions can we ensure the safety of 2,2 '-ethylene-1,2-diylbis (5-nitrobenzenesulfonic acid) during circulation and avoid accidents.
