1-Naphthalenesulfonic Acid, 2,6-Bis (1,1-Dimethylethyl) -, What is the production method of Sodium Salt?
The preparation of 2,6-bis (1,1-dimethylethyl) -1-naphthalenesulfonic acid, sodium salt, is related to the technology of chemical synthesis. In the past, the preparation of this compound often followed the traditional organic synthesis path.
First, 1-naphthalenesulfonic acid is used as the initial raw material. To obtain the target product, the naphthalene ring needs to be modified first. The introduction of 2,6-bis (1,1-dimethylethyl) onto the naphthalene ring depends on the electrophilic substitution reaction. Under suitable reaction conditions, such as selecting an appropriate catalyst and controlling the temperature, the 1-naphthalenesulfonic acid interacts with the tert-butylation reagent. The commonly used tert-butyl reagent may be a system composed of tert-butyl alcohol and a strong acid, such as sulfuric acid or p-toluenesulfonic acid. During the reaction process, the acid can protonate the tert-butyl alcohol to form an active carbon positive ion, which can then launch an electrophilic attack on the 2,6-position of the naphthalene ring to achieve the synthesis of 2,6-bis (1,1-dimethylethyl) -1-naphthalenesulfonic acid.
Second, when 2,6-bis (1,1-dimethylethyl) -1-naphthalenesulfonic acid is synthesized, to obtain its sodium salt, just mix the resulting acid with an appropriate amount of alkali metal hydroxide, usually sodium hydroxide, in a solvent for neutralization. Common solvents, such as water or alcohols mixed with water, are acceptable. In this reaction process, the sulfonic acid group in the acid reacts with sodium hydroxide, and the hydrogen of the sulfonic acid group is replaced by sodium ions to form 2,6-bis (1,1-dimethylethyl) -1-naphthalenesulfonic acid, sodium salt.
After the reaction is completed, the separation and purification of the product is also crucial. The method of recrystallization can be used to select a suitable solvent according to the difference in solubility between the product and the impurities in different solvents, so that the product can be crystallized and precipitated from the solution, so as to separate from the impurities to obtain pure 2,6-bis (1,1-dimethylethyl) -1-naphthalenesulfonic acid and sodium salt. Although this preparation method has gone through complicated steps, in order to obtain high-purity target products, each step needs to be carefully controlled in order to obtain ideal results.
1-Naphthalenesulfonic Acid, 2,6-Bis (1,1-Dimethylethyl) -, What are the storage conditions for Sodium Salt?
Sodium 2,6-di-tert-butyl-1-naphthalene sulfonate, a compound commonly used in the field of fine chemicals. Its storage conditions are critical, related to its quality and stability.
At the time of storage, the first environment is dry. If the environment is humid, water vapor is easy to interact with the compound. Because of its certain water solubility, it may cause agglomeration after being damp, which affects its fluidity and dispersion, and even causes chemical changes, resulting in a decrease in active ingredients. Therefore, it should be stored in a dry warehouse, and the humidity should be controlled at 40% -60%.
The second is temperature. This compound is more sensitive to temperature, and high temperature may accelerate reactions such as decomposition and oxidation. If the temperature is too high, the molecular activity will be enhanced, and the structure may be damaged. Therefore, it should be stored in a cool place, preferably at a temperature of 5-25 ° C. Avoid direct sunlight, ultraviolet rays in sunlight or trigger photochemical reactions to deteriorate the compound.
Furthermore, the storage place should be well ventilated. Good ventilation can disperse harmful gases that may be generated and avoid potential safety hazards caused by high local concentrations. At the same time, store separately from oxidants, acids and other substances. Due to the chemical activity of the compound, contact with the above substances or cause violent reactions, endangering storage safety.
After taking it, be sure to seal the package. Prevent air and water vapor from entering again to ensure that the quality of the remaining compounds is not affected. Following the above storage conditions, the quality and properties of sodium 2,6-di-tert-butyl-1-naphthalenesulfonate can be effectively guaranteed, so that it can play its due role in production and application.
