3,5-Bis (triethylamino) benzenesulfonate barium salt is a chemical substance. Its properties are unique and have multiple chemical properties.
Looking at its structure, above the benzene ring, there are bis (triethylamino) groups at the 3rd and 5th positions, and they are accompanied by a sulfonate barium salt structure. This unique structure gives it a specific chemical activity.
In terms of solubility, the sulfonate barium salt part may have a certain solubility in polar solvents due to the hydrophilicity of the sulfonate group. However, the bis (triethylamino) group has certain organic properties, or affects its solubility in water, resulting in its solubility is not very high.
When it comes to chemical stability, the structure of the benzene ring gives it a certain stability, but the barium salt of the sulfonic acid may be more sensitive to environmental factors. In case of strong acid, the barium salt of the sulfonic acid may react, the barium ion may be replaced, and the sulfonic acid group may be released. In case of strong base, the integrity of its structure is affected because the triethylamino group is basic, or reacts with it such as acid-base neutralization.
It may have unique uses in the field of organic synthesis. Bis (triethylamino) groups may be used as reaction check points to participate in reactions such as nucleophilic substitution and electrophilic addition. The barium salt part of the sulfonic acid may affect the selectivity and rate of the reaction, or act as a catalyst auxiliary in some reaction systems to regulate the reaction process.
In the field of materials science, if it is introduced into polymer materials, its special structure may endow the material with new properties. Such as changing the surface charge distribution of the material, affecting the interaction between the material and other substances, thereby improving the adsorption and dispersion properties of the material.
In summary, 3,5-bis (triethylamino) benzenesulfonate barium salt has potential application value in many fields of chemistry due to its unique structure. Its chemical properties are complex and interesting, and it is a substance worthy of exploration in chemical research.

3% 2C5-bis (triethylamino) silylbenzoic anhydride, the synthesis method of this compound, let me explain in detail.
To synthesize this compound, you can first take benzoic anhydride as the starting material. Put benzoic anhydride in a suitable reaction vessel, add an appropriate amount of organic solvents, such as dichloromethane, chloroform, etc., to help it dissolve and form a uniform reaction system.
Then, slowly add the silanizing reagent containing triethylamine group dropwise. This process requires careful operation to control the dripping speed and reaction temperature. The temperature should be maintained in the low temperature range, such as 0 ° C to 5 ° C, to prevent side reactions from occurring. After the dripping is completed, gradually heat up to room temperature to allow the reaction to proceed fully.
During the reaction process, the reaction progress can be monitored by means of thin layer chromatography (TLC). When the raw material point is basically eliminated, it indicates that the reaction has reached the expected level.
At this time, the reaction mixture is post-treated. First wash with an appropriate amount of dilute acid solution, such as dilute hydrochloric acid, to remove unreacted alkaline substances. Then wash with saturated saline water to reduce the water content in the organic phase. Subsequently, dry the organic phase with a desiccant such as anhydrous sodium sulfate to remove the remaining moisture.
Finally, the organic solvent is removed by reduced pressure distillation or the like to collect the target product. If the purity of the product is poor, it can be further purified by column chromatography and other methods. Appropriate eluents, such as petroleum ether and ethyl acetate mixed solvents, can be selected to achieve effective separation of impurities according to the polarity difference of the product, so as to obtain high-purity 3% 2C5 -bis (triethylamino) silylalkylbenzoic anhydride.
The key to the synthesis lies in the precise control of the reaction conditions and the careful operation of the post-treatment steps, so as to ensure the smooth progress of the synthesis and the good quality of the product.

3,5-Bis (triethylamino) benzenesulfonate guanoxime, when storing and transporting, be sure to pay attention to many matters.
First, it concerns the storage environment. This substance should be stored in a cool, dry and well-ventilated place. Because the cool environment can reduce the risk of changes due to excessive temperature, drying can avoid moisture hydrolysis, and good ventilation can disperse harmful gases that may accumulate. Do not place in a humid or high temperature place to prevent deterioration and damage its quality and efficacy.
Second, as far as packaging is concerned. The packaging must be tight to ensure that there is no leakage. It should be packed in a container with good sealing performance to prevent contact with outside air, moisture, etc. Packaging materials also need to be adapted to resist the chemical action of this substance and do not react with it to ensure its stability.
Third, during transportation, severe vibration and collision should be avoided. Due to its nature or accidents caused by strong vibration, the transportation of the vehicle should be smooth. And it should be transported separately from other chemicals to avoid danger caused by the interaction of different substances.
Fourth, the operator should also take good protection. During handling, appropriate protective equipment, such as gloves, goggles, etc., is required to prevent this substance from contacting the skin and eyes and causing injury. In case of accidental contact, rinse with plenty of water immediately and seek medical attention in time according to the injury.
In conclusion, when storing and transporting guanoxime 3,5-bis (triethylamino) benzenesulfonate, full attention must be paid to the environment, packaging, transportation process, and personnel protection in order to ensure its safety and quality.
