3-Mercapto-1-Propanesulfonic Acid Sodium Salt in Storage
Sodium 3-mercapto-1-propanesulfonate is an important chemical substance. When storing, pay attention to many key matters.
First, temperature is crucial. This substance should be stored in a cool place. If the temperature is too high, it is easy to change its chemical properties or cause undesirable conditions such as decomposition. Because high temperature can accelerate the rate of molecular movement, intermolecular reactions are more likely to occur, which in turn affects its stability. Therefore, the temperature should be selected where the temperature is relatively constant and low, such as a warehouse with a temperature below 20 ° C.
Second, the humidity should not be underestimated. It needs to be placed in a dry environment. If the ambient humidity is too high, the moisture will easily interact with the substance. Some sulfur-containing compounds are easily oxidized in humid environments, as is sodium 3-mercapto-1-propanesulfonate. Once oxidized, its chemical structure and properties will change, affecting subsequent use. Therefore, the storage place should be equipped with dehumidification equipment to maintain humidity below 60%.
Third, it is indispensable to store in the dark. Light, especially strong light, or lead to luminescent chemical reactions, change the molecular structure of the substance. Light energy can cause chemical bonds within the molecule to break and recombine, reducing its purity and quality. Therefore, it should be stored in a brown bottle or opaque container and stored in a dark place.
Fourth, avoid mixing with other substances. This substance is chemically active and may react with certain oxidants, acids, bases, etc. Once mixed, or cause violent chemical reactions, or even cause danger. If it cannot be placed in the same place as strong oxidants such as potassium permanganate, it should be stored separately and marked to prevent misuse.
Store sodium 3-mercapto-1-propanesulfonate, be sure to start from temperature, humidity, light and isolation from other substances to ensure its quality and stability.
What is the synthesis method of 3-Mercapto-1-Propanesulfonic Acid Sodium Salt?
Sodium 3-mercapto-1-propanesulfonate, the preparation method of which is often followed by craftsmen in the past.
First take suitable starting materials, such as sodium acrylate sulfonate and sodium hydrosulfide, and the two are combined in a suitable reaction vessel. The material of the container should be carefully selected to prevent undue reaction with the reactants.
During the reaction, temperature control is the key. Usually in a warm water bath, the temperature is slowly raised to a suitable degree, about 50 to 70 degrees Celsius. This temperature can not only promote the reaction, but also prevent the reaction from being too dramatic and generating many by-products.
In the reaction system, stirring is also indispensable. Stirring at a steady rate allows sodium propene sulfonate and sodium hydride to fully blend, and the molecules can collide frequently to accelerate the reaction process.
After several times of reaction, when the characteristics of the system reach a specific image, such as the color, taste and some physical properties of the reaction solution are stable, it can be regarded as the end of the reaction.
Then, the reaction product is separated and purified. Filtration is often used to remove its insoluble impurities. The filtrate is concentrated to increase the concentration of the product.
After concentration, recrystallize with an appropriate solvent. When selecting the solvent, it is necessary to depend on the solubility of the product, so that the product can be precipitated into pure crystals in the solvent.
After several recrystallization, high-purity sodium 3-mercapto-1-propanesulfonate can be obtained, which is crystal clear and suitable for many chemical, pharmaceutical and other fields.
