Ethanesulfonic acid, 2-Bromo-, Sodium salt What is the synthesis method
The method for preparing sodium 2-bromoethane sulfonate (Ethanesulfonic acid, 2-Bromo-, Sodium salt) can follow the following steps:
First take an appropriate amount of ethylene and place it in a suitable reaction vessel. Introduce hydrogen bromide gas to make it add to ethylene. This process requires an appropriate catalyst, such as peroxide, under suitable temperature and pressure conditions, to promote the smooth progress of the reaction. Ethylene reacts with hydrogen bromide in a stoichiometric ratio of 1:1 to produce bromoethane. The reaction equation is: $CH_ {2} = CH_ {2} + HBr\ xrightarrow [] {catalyst} CH_ {3} CH_ {2} Br $.
After the formation of bromoethane, take another reactor and mix bromoethane with sodium sulfite solution. The two substitution reactions occur, and the bromine atom of bromoethane is replaced by sulfite ion, and then 2-bromoethane sulfonate is formed. During the reaction, attention should be paid to controlling the reaction temperature and the pH of the solution to make the reaction proceed smoothly. The reaction equation is: $CH_ {3} CH_ {2} Br + Na_ {2} SO_ {3}\ rightarrow CH_ {3} CH_ {2} SO_ {3} Na + NaBr $.
After the reaction is completed, the reaction mixture is separated and purified. First, the method of filtration is used to remove the insoluble impurities that may exist. Then adopt the method of crystallization, according to the difference of the solubility of sodium 2-bromoethanesulfonate at different temperatures, through cooling, concentration and other operations, so that sodium 2-bromoethanesulfonate crystallizes and precipitates. Finally, the crystals are washed with a suitable organic solvent, and the pure sodium 2-bromoethanesulfonate product can be obtained after drying.
Ethanesulfonic acid, 2-Bromo-, Sodium salt What to pay attention to when storing
Sodium 2-bromoethane sulfonate is a chemical substance, and many aspects need to be paid attention to when storing.
First, pay attention to the temperature and humidity of the storage environment. This substance should be stored in a cool and dry place. If the ambient temperature is too high, or it may cause a chemical reaction, resulting in damage to its stability; if the humidity is too high, it may cause deliquescence and affect its quality. If placed in a high temperature and humid place, or the properties of sodium 2-bromoethane sulfonate are changed, it cannot meet the needs of subsequent use.
Second, pay attention to its isolation from other substances. Because it has certain chemical activity, it cannot be co-stored with oxidizing, reducing substances and strong acids and alkalis. If it is mixed with oxidizing substances, or causes a violent oxidation reaction; contact with acids or bases, or cause reactions such as hydrolysis, change its chemical structure and properties.
Third, the choice of storage container is also crucial. A suitable and well-sealed container should be selected to prevent it from deteriorating in contact with air. Usually glass bottles or specific plastic containers can be selected, and the container material must not react with sodium 2-bromoethane sulfonate to maintain its chemical stability.
Fourth, the storage area should be well ventilated. Avoid high concentrations of sodium 2-bromoethane sulfonate in the local air due to volatilization and other reasons, which may cause safety hazards. At the same time, good ventilation also helps to maintain a suitable storage environment. When storing sodium 2-bromoethane sulfonate, it is necessary to fully consider the above points and operate with caution to ensure its quality and safety for subsequent use.
