2-Bromoethanesulphonic chemical stability of Acid Sodium Salt?
2-Bromoethane sulfonate sodium, its chemical properties are quite stable. This is because in the structure, the sulfonic acid radical group (- SO
) itself has a certain stability, and the chemical bond energy formed by the sulfur atom and the oxygen atom is higher, which endows the sulfonic acid radical group with a relatively stable structure.
And although the carbon-bromine bond in this compound is highly active, it can remain relatively stable under conventional conditions if there is no specific reagent or condition to initiate the reaction. For example, in a dry environment at room temperature, the substance can be stored for a long time without significant change.
However, under specific conditions, its stability will be affected. In a strongly alkaline environment, the carbon-bromine bond is vulnerable to attack by hydroxyl nucleophiles, and a substitution reaction occurs to generate sodium 2-hydroxyethane sulfonate. In addition, if the sulfonic acid group is oxidized at high temperatures and in the presence of strong oxidizing agents, such extreme conditions are not common in general environments. In general, under common laboratory and industrial storage and use conditions, sodium 2-bromoethane sulfonate is chemically stable.
2-Bromoethanesulphonic of Acid Sodium Salt
There are several common methods for the synthesis of 2-Bromoethanesulphonic Acid Sodium Salt.
First, the method of using bromoethane and sodium sulfite as raw materials. Slowly adding bromoethane to the aqueous solution of sodium sulfite requires careful temperature control. Because the reaction between the two is an exothermic reaction, if the temperature is too high, the side reaction will increase and the purity of the product will decrease. Usually at a moderate temperature, such as 60-80 ° C, when the reaction is stirred for several times. After the reaction is completed, the crude product of 2-bromoethane sulfonate can be obtained through concentration, crystallization and other processes, and then purified by recrystallization, which can improve the purity of the product. The reaction principle is that the bromine atom in bromoethane has strong activity, and can undergo nucleophilic substitution reaction with the sulfur atom in sodium sulfite, and the bromine atom leaves to form sodium 2-bromoethane sulfonate.
Second, ethylene, bromine and sodium sulfite are used as raw materials. First, ethylene and bromine are added to form 1,2-dibromoethane. This reaction is carried out in a suitable solvent, such as carbon tetrachloride, and the reaction conditions, such as temperature and light, need to be controlled to prevent side reactions. Then 1,2-dibromoethane reacts with sodium sulfite. At this time, the reaction conditions also need to be carefully regulated. Temperature and the proportion of reactants will affect the yield and purity of the product. After a series of post-treatments, such as extraction, distillation, crystallization, etc., the target product can be obtained. The advantage of this approach is that the raw material ethylene is widely sourced and the cost is relatively low, but there are many reaction steps, and each step needs to be properly controlled.
Third, ethanol is used as the starting material. First, ethanol is reacted with hydrogen bromide to obtain bromoethane. This reaction often reacts with sulfuric acid and sodium bromide to produce hydrogen bromide, which is then reacted with ethanol. After that, bromoethane is reacted with sodium sulfite as described above to obtain sodium 2-bromoethane sulfonate. The starting material ethanol for this route is inexpensive and easy to obtain, but it involves the preparation of hydrogen bromide, and the operation needs to be cautious because hydrogen bromide is corrosive and irritating.
2-Bromoethanesulphonic precautions when storing Acid Sodium Salt
2 - sodium bromoethane sulfonate (2 - Bromoethanesulphonic Acid Sodium Salt) is a chemical substance, and it should be stored with caution to keep it safe.
First, moisture-proof is essential. This substance is very easy to absorb moisture. After deliquescence, it not only affects the purity, but also changes its chemical properties. Therefore, when placed in a dry place, if conditions permit, a desiccant can be placed in the storage container to eliminate the danger of moisture.
Second, the temperature needs to be suitable. Under high temperature, the substance may decompose and damage its quality. It should be stored in a cool place. Generally speaking, the temperature should not exceed 30 ° C. It is appropriate to be near fire or heat sources to prevent accidents.
Third, it is heavy to avoid light. Light can also induce chemical reactions and cause deterioration. Therefore, store in dark containers, or wrap in light-shielding materials and hide in the dark to prevent strong light.
Fourth, store in isolation. Sodium 2-bromoethane sulfonate should not be stored in one place with oxidants, strong bases, etc. Because the substance encounters the oxidant, there may be a risk of violent reaction; contact with strong bases may also cause chemical reactions, endangering safety. It must be stored separately and strictly guarded.
Fifth, the packaging is sealed. Make sure the packaging is intact and tightly sealed to prevent material leakage, and avoid contact with outside air, moisture, etc., to ensure its stability. If the packaging is damaged, it needs to be replaced in time and re-sealed properly.
In short, when storing sodium 2-bromoethane sulfonate, care must be taken to ensure the quality and safety of the material by considering all aspects of moisture prevention, temperature control, light protection, isolation and sealing.
