3- {[Ethyl (Phenyl) Amino] Methyl} Benzenesulfonic Acid
3 - {[Ethyl (Phenyl) Amino] Methyl} Benzenesulfonic Acid, this is an organic compound, or 3 - {[ethyl (phenyl) amino] methyl} benzenesulfonic acid in Chinese. Its chemical properties are as follows:
1. ** Acidic **: The sulfonic acid group (\ (- SO_ {3} H\)) gives the compound acidity. In aqueous solution, the sulfonic acid group can ionize hydrogen ions (\ (H ^{+}\)), makes the solution acidic. This acidity is quite significant, and it is stronger than ordinary carboxylic acids. Because of its sulfonic acid group, the sulfur atom is connected to multiple oxygen atoms, and the electron cloud is biased towards the oxygen atom, resulting in the enhancement of the positive electricity of the sulfur atom, which is more likely to attract the electrons of the hydroxyl group in the sulfonic acid group, and promote the departure of hydrogen ions. This acidic property allows it to neutralize with bases and generate corresponding salts. If it reacts with sodium hydroxide (\ (NaOH\)), it will generate 3- {[ethyl (phenyl) amino] methyl} sodium benzene sulfonate and water.
2. ** Hydrophilic **: Sulfonic acid basically has good hydrophilicity. The compound has a certain solubility in water because of its sulfonic acid group. However, there are still hydrophobic groups such as ethyl and phenyl in the molecule, which will weaken its water solubility. In general, compared with sulfonic acid compounds containing only simple alkyl groups, their water solubility is slightly inferior. However, in the mixed system of some polar organic solvents and water, the solubility may be improved.
3. ** Substitution reaction **: Substitution reaction can occur on the benzene ring. Because the methyl group of the amino group is connected to the benzene ring, the amino group has a electron-giving conjugation effect, which will increase the electron cloud density of the benzene ring, especially the ortho and para-positions of the amino group. Therefore, electrophilic reagents are prone to attack the ortho and para-positions of the benzene ring, and electrophilic substitution reactions such as halogenation, nitration, and sulfonation occur. For example, under appropriate conditions, when reacting with bromine, bromine atoms may replace hydrogen atoms in the ortho and para-positions of the benzene ring. < b ** Stability **: From a structural perspective, the compound is relatively stable. The benzene ring has a conjugated system, which can enhance molecular stability. Nitrogen atoms are connected to ethyl and phenyl groups, and the formed amino structure is also relatively stable. However, under extreme conditions such as strong oxidation and strong reduction, the molecular structure may be damaged. In case of strong oxidants, sulfonic acid groups may be further oxidized, and the benzene ring may also be oxidized to open the ring.

3- {[Ethyl (Phenyl) Amino] Methyl} Benzenesulfonic Acid
To prepare 3 - {[Ethyl (Phenyl) Amino] Methyl} Benzenesulfonic Acid, you can follow the following ancient method.
First take an appropriate amount of benzaldehyde, which is the key starting material. In a suitable reaction vessel, mix benzaldehyde with ethylaniline. The ratio of the two needs to be precisely weighed to achieve the best reaction effect. When the two meet, under mild heating conditions, slowly stir to promote intermolecular interaction and open the door to the reaction.
During the reaction process, pay close attention to temperature changes. This reaction should be carried out in a moderate temperature range. If the temperature is too high, it may cause side reactions and the product will be impure. If the temperature is too low, the reaction will be slow and take a long time. After the initial reaction of the two, a certain intermediate product is generated, and a sulfonating reagent is introduced. The choice of sulfonating reagent is crucial. Concentrated sulfuric acid or fuming sulfuric acid are common, but it needs to be considered according to the actual situation.
When introducing a sulfonating reagent, the addition rate and amount should also be controlled. Add slowly, while maintaining the agitation of the reaction system, so that the sulfonating reagent is uniformly dispersed and fully contacted with the previously generated intermediate product. This sulfonation step is a key step in imparting the sulfonate group to the product.
After the reaction is completed, the product is mixed in the reaction system. At this time, separation and purification are required. The method of extraction can be used first, and a suitable extractant can be selected to extract the target product from the system. Subsequently, the product is further purified by distillation, recrystallization and other means Distillation can remove volatile impurities, and recrystallization can precipitate the product in a pure crystal form to obtain a high purity of 3- {[Ethyl (Phenyl) Amino] Methyl} Benzenesulfonic Acid. The whole process requires fine operation and strict adherence to the conditions of each step to obtain a satisfactory product.
3- {[Ethyl (Phenyl) Amino] Methyl} Benzenesulfonic Acid What are the precautions during storage
