What are the physical properties of 3- (Benzothiazolyl-2-Mercapto) -Propyl-Sulfonic Acid and Sodium Salt?
Sodium 3- (benzothiazole-2-mercapto) propyl sulfonate is an organic compound that has applications in many fields. Its physical properties are quite critical and are described in detail by you.
Looking at its properties, this compound is often in the state of white to off-white crystalline powder, with pure color and uniform quality, fine but no variegated or agglomerated appearance. This form is conducive to storage and transportation, and it is also easy to measure accurately in subsequent use.
When it comes to solubility, it is soluble in water and can be rapidly dispersed and dissolved in water to form a uniform solution. This property makes it able to fully contact and react with other substances in a reaction system or application scenario using water as a medium. For example, in the application of some water-based paint additives, its good water solubility can be used to evenly disperse in the paint to exert its specific effect. However, its solubility in organic solvents such as ethanol and acetone is poor, and it can only be dissolved in a small amount or almost insoluble in such solvents. This point requires special attention in the process involving organic solvents.
Melting point is an important physical parameter, and its melting point is in a specific temperature range. Accurate determination of melting point is of great significance for identifying the purity of the compound. If the purity of the compound is high, the melting point will be relatively stable and close to the theoretical value; if it contains impurities, the melting point may be offset and the melting range will also become wider.
In addition, its hygroscopicity cannot be ignored. The compound has a certain degree of hygroscopicity and is easy to absorb moisture in the air in humid environments. After moisture absorption, or cause its physical morphology to change, such as agglomeration, etc., it may also affect its chemical stability and performance. Therefore, it needs to be stored in a dry place and tightly sealed to maintain its good physical state and chemical properties.
The above are the main physical properties of sodium 3- (benzothiazole-2-mercapto) propyl sulfonate. It is important to understand these properties for their correct use, storage and related process design.
3- (Benzothiazolyl-2-Mercapto) -Propyl-Sulfonic Acid, What are the chemical properties of Sodium Salt
Sodium 3- (benzothiazole-2-mercapto) propyl sulfonate, this compound is an organic compound, which has applications in many fields and its chemical properties are quite characteristic.
First of all, from the structural point of view, the compound contains benzothiazole group, mercapto group and sodium propyl sulfonate part. The benzothiazole group gives it a certain stability and special electronic effects. Mercapto (-SH) is an extremely active functional group with strong reductivity. Under appropriate conditions, mercapto groups are easily oxidized and can form disulfide bonds (-S-S-), which is also very important in the structural stability of biomolecules such as proteins. At the same time, because the sulfur atom in the sulfhydryl group has lone pairs of electrons, it can complexe with a variety of metal ions, which can be used for the detection, separation and enrichment of metal ions.
Furthermore, sodium propyl sulfonate partially imparts good water solubility to the compound. Sulfonic acid group (-SO < Na
) is a strong hydrophilic group, which makes the substance easily soluble in water and can participate in various reactions in aqueous systems. In some surfactant systems, it can use this water solubility to participate in the regulation of surface tension and other properties.
In addition, the benzothiazole ring conjugate system in this compound makes it capable of absorbing ultraviolet rays at specific wavelengths, or can be applied to sunscreen and other related products. The complexity of its overall structure and the synergy of various functional groups make it exhibit diverse reactivity and properties in different chemical environments, and has potential application value in materials science, biochemistry, medicinal chemistry and other fields.
What is the preparation method of 3- (Benzothiazolyl-2-Mercapto) -Propyl-Sulfonic Acid, Sodium Salt?
The method for preparing the sodium salt of 3- (benzothiazole-2-mercapto) propyl sulfonate is described below.
First take benzothiazole and an appropriate thiol reagent, add an appropriate amount of organic solvent, such as ethanol or dichloromethane, in a suitable reaction vessel to help the reactants dissolve and disperse evenly. Then add alkali substances, such as sodium hydroxide or potassium hydroxide, to adjust the pH of the reaction system and make the reaction environment conducive to the reaction. The amount of base needs to be precisely controlled, determined according to the molar ratio of the reactants, generally slightly higher than the theoretical amount, in order to promote the reaction in the direction of generating the target product.
Then, slowly add the reagent containing propyl sulfonic acid structure, and stir while adding to make the reactants fully contact and accelerate the reaction process. The stirring rate needs to be moderate. If it is too fast, it will easily cause the system to be unstable, and if it is too slow, the reaction mixing will not be sufficient. The reaction temperature is also a key factor, and it is usually controlled within a certain range, such as 40-60 degrees Celsius. This temperature range not only guarantees the reaction rate, but also avoids side reactions caused by excessive temperature. During the reaction process, the reaction process can be closely monitored. By means of thin-layer chromatography (TLC) or high-performance liquid chromatography (HPLC), the consumption of reactants and the generation of products can be known in real time.
When the reaction reaches the expected level, that is, the reactant is basically converted into the target product, and the reaction mixture is post-processed. The reaction liquid is first cooled to room temperature, and then separation operations are carried out, such as removing insoluble impurities by filtration or separating the organic and aqueous phases by extraction, so that the target product is enriched in a specific phase. Next, the phase containing the target product is purified to remove residual impurities. Column chromatography can be used to select suitable silica gel columns and eluents, and separation and purification can be achieved according to the difference in the partition coefficient between the target product and impurities between the stationary and mobile phases.
Finally, the purified product is dried to remove the residual solvent to obtain pure 3- (benzothiazole-2-mercapto) propyl sulfonate sodium salt. The drying method can be selected from vacuum drying or freeze drying to ensure that the water content of the product meets the quality requirements. In this way, the preparation of 3- (benzothiazole-2-mercapto) propyl sulfonate sodium salt is completed.
