What is the chemical structure of 1-Azulenesulfonic Acid, 3,8-Dimethyl-5- (1-Methylethyl) -, Sodium Salt?
The sodium salt of 3,8-dimethyl-5- (1-methylethyl) azulene-1-sulfonic acid, whose chemical structure can be gradually analyzed from the following.
This compound has an azulene as the parent nuclear structure. Azulene is a non-benzene aromatic hydrocarbon with a unique fused system of seven-membered rings and five-membered rings. This fused structure endows it with special chemical activity and electron cloud distribution.
Linked to the sulfonic acid group (-SO-H) at the first position of the azulene ring, the sulfonic acid group is a strong acidic group, which will significantly affect the solubility and chemical properties of the molecule, making it exhibit good ionization tendency and hydrophilicity in water.
The 3rd and 8th positions are connected with methyl groups (-CH), respectively. The introduction of methyl groups changes the spatial structure of the molecule and the distribution of electron cloud density, which affects its physical and chemical properties, such as melting point, boiling point, and interaction with other substances.
5-linked isopropyl (1-methylethyl, -CH (CH) ²), isopropyl is a large branched alkyl group, which increases the steric resistance of the molecule, and also affects the spatial structure, physical properties, and chemical reactivity of the compound.
Finally, the compound exists in the form of sodium salt, that is, the hydrogen atom of the sulfonic acid group is replaced by sodium ions (Na 🥰) to form the sodium sulfonate salt structure (-SO 🥰 Na). The formation of this salt enhances the solubility of the compound in water, and due to the presence of sodium ions, it can exist stably in the form of ions in solution, and is widely used in many fields. For example, as an active ingredient of surfactants, with its unique chemical structure, it can reduce the surface tension of liquids and exhibit good properties such as emulsification, dispersion, and solubilization.
1-Azulenesulfonic Acid, 3,8-Dimethyl-5- (1-Methylethyl) -, What are the physical properties of Sodium Salt?
3,8-Dimethyl-5- (1-methethyl) azulene-1-sulfonic acid, the physical properties of this product are as follows:
In terms of external appearance, it is often powder or crystalline, and it is uniform. Its color is multi-white to white, and the color is high.
Solubility is special, and it has good solubility in water, which can form a clear solution. This property is due to the presence of sulfonic acid groups in its molecules, which are easy to form strong interactions with water molecules, so that the whole molecule can be dispersed in water. However, the solubility of the phase is limited in the solution. For example, in the normal solution of n-hexane and ether, the dissolution is caused by the mismatch of the solubility of the molecule.
Melting is also an important physical property. It has a specific melting value. In the addition process, when the melting degree is reached, the crystal begins to disintegrate, and the material is composed of solid and liquid. This melting degree is determined by factors such as molecular force and lattice energy.
In terms of density, its density has a certain value, which reflects the amount of matter at the location. The size of the density depends on the molecular phase, the molecular density, and the density of the molecular arrangement. The larger the molecular weight, the denser the molecular arrangement, and the higher the density.
Therefore, the physical properties of 3,8-dimethyl-5- (1-methylethyl) azulene-1-sulfonic acid are determined by their molecules, and they have important effects in different domains.

1-Azulenesulfonic Acid, 3,8-Dimethyl-5- (1-Methylethyl) -, Sodium Salt What is the production method?
The method of preparing the sodium salt of 3,8-dimethyl-5- (1-methethyl) sulfonate is as follows:
The first azulene compound is taken as the starting material, because of its unique azulene ring structure, which lays the foundation for the target product. In an appropriate reaction vessel, add a certain amount of the azulene raw material, and match it with a suitable organic solvent, such as aromatic hydrocarbon or halogenated hydrocarbon solvent, which can effectively dissolve the raw material and create a stable reaction environment.
Subsequently, a sulfonating agent is introduced, such as concentrated sulfuric acid or fuming sulfuric acid. During the sulfonation process, the reaction temperature and time are strictly controlled. The temperature should be maintained at a specific range, such as a moderate low temperature start, and then gradually rise to a suitable temperature to prevent excessive sulfonation. The reaction time also needs to be precisely controlled, and it needs to be adjusted in a timely manner according to the reaction process and monitoring results.
After the sulfonation reaction is completed, 3,8-dimethyl-5- (1-methylethyl) sulfonic acid is obtained, and the sodium salt conversion step is carried out. Move the sulfonic acid product to the new reaction system, and add an appropriate amount of sodium hydroxide solution or basic sodium salt reagents such as sodium carbonate. This step of the reaction is carried out gently, and attention should be paid to controlling the reaction rate to avoid local overheating or over-alkali causing the product to decompose. After the reaction is completed, it is separated and purified. Filtration, extraction, recrystallization and other methods are often used to remove unreacted raw materials, by-products and impurities, and finally the pure sodium salt product of 3,8-dimethyl-5- (1-methylethyl) sulfonate can be obtained.
1-Azulenesulfonic Acid, 3,8-Dimethyl-5- (1-Methylethyl) -, Sodium Salt What are the precautions during use?
When using this sodium salt called 3,8-dimethyl-5- (1-methylethyl) -azulenesulfonic acid, many things need to be paid attention to.
First, it is related to its chemical properties. This substance is in the form of sodium salt and has specific chemical activity and stability. During use, be careful to avoid contact with substances that can react with sodium salts, such as certain acids. Acids meet with sodium salts, or chemically react, causing substances to deteriorate, and even causing dangerous conditions, such as gas generation, heat release, etc. Like ancient alchemy, different medicinal ingredients are mixed, or accidents.
Second, its solubility also needs attention. Be familiar with its dissolution in various solvents. In water or organic solvents, the solubility difference or affect the way of use. If used as a solution, the solubility is not good, or the dispersion is uneven, affecting the effect, just like the preparation of herbs, the drug dissolves poorly, and the efficacy is difficult to recognize.
Third, safety protection must not be forgotten. Although its toxicity is not known in detail, protective measures should still be taken during operation. Wear appropriate protective equipment, such as gloves and goggles, to avoid skin contact and eye splashing. Once in contact, it should be dealt with quickly according to the established process, such as rinsing with a lot of water, and seeking medical treatment if necessary, just like the ancients who dealt with toxic contamination, and had a rigorous way to deal with it.
Fourth, storage conditions are also critical. Store in a dry, cool and ventilated place, away from fire sources and oxidants. Improper storage, or cause the nature of the material to change and impair the efficacy, just like an ancient book, it needs to be properly preserved for a long time. When using this substance, you must be careful and follow the specifications to achieve the intended purpose and ensure safety.
