What are the physical properties of 3-Bromopropanesulfonic Acid Sodium Salt?
Sodium 3-bromopropanesulfonate, its physical properties are as follows:
This substance is mostly white crystalline powder at room temperature, pure and delicate in appearance, like first snow, light and loose in weight. It smells, has no pungent and unpleasant odor, and has a peaceful breath.
When it comes to solubility, sodium 3-bromopropanesulfonate is easily soluble in water, just like salt entering a clear spring, instantly dissipating formless, forming a uniform and stable solution. This property is derived from the hydrophilicity of sulfonic acid groups and sodium ions in its molecular structure. The synergistic effect of the two makes the substance form a strong interaction force with water molecules.
Furthermore, its melting point is quite fixed, and it will gradually change from solid state to liquid state at a specific temperature. This temperature is one of the important physical constants of the substance, reflecting the stability of its internal lattice structure and the strength of intermolecular forces. Accurate determination of its melting point is of great significance for identifying the substance and determining its purity.
Its density also has characteristics and remains constant under established conditions. Compared with similar compounds, this value can highlight the difference in the compactness of molecular stacking and the relative mass of atoms. It is an indispensable parameter for the design and operation of processes such as material measurement, mixing and separation in chemical production.
In addition, the hygroscopicity of sodium 3-bromopropanesulfonate is also worthy of attention. Due to the hydrophilic groups in its molecular structure, it is easy to absorb moisture in the air in an environment with high humidity, just like a sponge absorbs water, causing its own deliquescence. This requires that during storage and use, it is necessary to pay attention to moisture protection to avoid affecting its quality and performance.
What is the preparation method of 3-Bromopropanesulfonic Acid Sodium Salt?
The method of preparing sodium 3-bromopropane sulfonate is to take 3-bromopropene as the raw material and undergo an addition reaction with sodium bisulfite. This is a key step. The reaction principle is based on the activity of double bonds, and the bisulfite ion attacks the double bond nucleophilically, so as to obtain the sodium 3-bromopropane sulfonate intermediate.
The specific operation is to slowly add 3-bromopropene to the aqueous solution containing sodium bisulfite in a certain proportion in a suitable reaction vessel with an appropriate amount of water as the solvent. The reaction process requires close attention to temperature changes and should be maintained in a moderate range, about 40-60 degrees Celsius. This temperature range ensures that the reaction rate is appropriate, neither too fast to increase side reactions, nor too slow to make the reaction take too long.
When the reaction proceeds, there may be subtle changes in the color of the solution, accompanied by slight heat release. After a certain reaction time, about 2-4 hours, the reaction progress is monitored by thin layer chromatography or high performance liquid chromatography. When the raw material 3-bromopropene is basically reacted completely, it is regarded as the end point of the reaction.
After that, the reaction solution is treated. First, the sodium hydroxide solution is neutralized to neutral. This step aims to adjust the pH of the solution so that the product exists stably in the form of sodium salt. Then, most of the solvent water is removed by vacuum distillation to increase the concentration of the product. Subsequently, the concentrate is cooled to a low temperature, such as 0-5 degrees Celsius, to induce the crystallization of sodium 3-bromopropanesulfonate.
Finally, the crystals are collected by suction filtration and washed with an appropriate amount of low-temperature ethanol to remove impurities. The resulting crystals are dried in a vacuum oven at a temperature of 40-50 degrees Celsius to obtain a pure sodium 3-bromopropanesulfonate product. In this way, according to this series of steps, the target product can be obtained.
3-Bromopropanesulfonic Acid Sodium Salt in Storage
3-Bromopropane sulfonate sodium salt, when hiding, all matters should be paid attention to. This material is special and sensitive to environmental conditions.
bear the brunt, temperature and humidity must be carefully checked. It should be stored in a cool place, protected from sun exposure and high temperature. Under high temperature, it may change its biomass, such as the risk of decomposition. If the temperature exceeds a certain limit, the molecular structure may be damaged, and the efficacy or function will be reduced. Humidity should not be underestimated. Excessive humidity may cause deliquescence. After this product absorbs moisture, it not only changes its shape, but also may cause chemical reactions, resulting in quality deterioration. Therefore, in the place where it is stored, it is advisable to control the humidity in a moderate area, such as with desiccant to supplement it to keep it dry.
Furthermore, isolation from other things is also necessary. It should not be co-stored with strong oxidants, strong bases, etc. Strong oxidants have strong oxidizing properties, and when they are encountered, they are prone to oxidation reactions, or risk of combustion or explosion. Strong bases react with it or neutralize acid and base, causing the composition to change and lose its original properties. It must be stored in a separate container, carefully sealed to prevent it from mixing with other substances.
Again, the storage place should be well ventilated. Good wind can remove harmful gases that may escape, so as to avoid accumulation and danger. And ventilation can slow down the fluctuation of temperature and humidity, and ensure the stability of the environment.
Also, the label logo must not be ignored. The bottle body should be used as the detailed information of the product name, specification, date, etc. Clear identification, easy access, and beneficial for traceability and management. In case of an accident, it can also quickly identify the ingredients and facilitate emergency response.
Hidden 3-bromopropanesulfonate sodium salt, it must be in a place with suitable temperature and humidity and good ventilation, strictly separated from other objects, and clearly marked, so as to ensure its quality and safety for future use.
3-Bromopropanesulfonic the market price of Acid Sodium Salt
3-Bromopropanesulfonate sodium salt, the market price of this product often changes for many reasons. Its price is affected by the situation of raw materials, technology, supply and demand.
In the past, if raw materials were abundant and the process was mature, the price might stabilize. However, if raw materials are scarce or the process encounters obstacles, the price will rise. On the supply and demand side, the demand is strong and the supply is small, and the price will also rise; otherwise, the price will fall.
The view of "Tiangong Kaiwu", although there is no special treatise on such things, its method of talking about all kinds of things can be cited as a lesson. When it comes to the output and production of all kinds of materials, it is said that it is difficult and easy, rare and complex. 3-Bromopropane sulfonate sodium salt, if it is difficult to produce, requires multiple processes and consumes a lot of raw materials, the price will be high. And if there is less output, it will cause inconvenience in circulation and also increase the price.
In today's market, the price may range from tens to hundreds of yuan per kilogram. However, the chemical market is changeable, and if you want to know the exact price, you should consult the chemical raw material suppliers, and their quotations will be accurate according to the current reality.
