What is the preparation method of 3-Nitrobenzenesulfonate?
3-Nitrobenzenesulfonate is 3-nitrobenzene sulfonate, which is prepared by combining 3-nitrobenzene sulfonic acid with suitable bases. Usually, bases such as sodium hydroxide or potassium hydroxide are mixed with 3-nitrobenzene sulfonic acid in an appropriate amount of solvent, such as water, and gently stirred to make it fully react.
Looking at this reaction, 3-nitrobenzene sulfonic acid encounters a base, and the neutralization effect of the sulfonic acid group ($- SO_ {3} H $) with the base is significant. Taking sodium hydroxide as an example, the reaction formula is as follows: 3 dollars - nitrobenzene sulfonic acid + NaOH\ longrightarrow 3 - nitrobenzene sulfonic acid + H_ {2} O $. This reaction is stable. The acidic nature of the sulfonic acid combines with the hydroxide ion of the base, and the corresponding 3-nitrobenzene sulfonate is obtained in raw water.
When reacting, attention should be paid to the control of temperature, and it should not be too high or too low. If it is too high, it may cause a cluster of side reactions, and if it is too low, the reaction will be slow and time-consuming. Generally speaking, room temperature or slightly higher than room temperature, between about 20-30 ° C, is quite suitable.
After the reaction is completed, 3-nitrobenzene sulfonate is obtained in the solution. It can be purified by evaporating the solvent to make the salting out, and then by recrystallization, using a suitable solvent, such as ethanol-water mixed solvent, to remove impurities and obtain a pure 3-nitrobenzene sulfonate product. In this way, high-purity 3-nitrobenzene sulfonate can be obtained for subsequent chemical, scientific research and other purposes.
