Disodium 2,2'-[Biphenyl-4,4'-Diyldi(E)Ethene-2,1-Diyl]Dibenzenesulfonate

This is a compound of disodium 2,2 '- [biphenyl-4,4' -diyl di (E) ethylene-2,1-diyl] diphenylsulfonate. Looking at its name, its chemical structure can be inferred. "Biphenyl-4,4 '-diyl" is a structural unit connected to the two styrene rings at the 4,4' -position. "Bis (E) ethylene-2,1-diyl" indicates that it contains two vinyl groups with the (E) configuration and is connected to the biphenyl 4,4 '-position, respectively. This vinyl group is connected to a styrene ring at both ends, while "diphenylsulfonate" indicates that the styrene ring has a sulfonic acid group and forms a salt with sodium ions. Therefore, in its chemical structure, biphenyl is the center, and the benzene ring is connected by a vinyl group with (E) configuration on both sides, and the benzene ring has a sulfonic acid group and forms a sodium salt. In this way, the approximate chemical structure of this compound can be obtained.

This substance is called disodium 2,2 '- [biphenyl-4,4' -diyl di (E) ethylene-2,1-diyl] diphenyl sulfonate. Its safety needs to be considered in many aspects.
From the chemical structure, this compound contains biphenyl, ethylene and benzenesulfonate structures. The biphenyl structure has a certain stability, and the benzenesulfonate part usually makes the substance have good water solubility. Generally speaking, compounds containing such structures are chemically stable under suitable conditions, and are not easy to react violently with common substances suddenly. It is acceptable to preliminarily infer their safety from the structural level.
However, safety is also closely related to the application scenario. If used in industrial production, in the synthesis, storage and transportation links, it is necessary to consider its interaction with contact materials and environmental factors. Because it is a salt, it may affect the material of the storage container in a humid environment. If the container is not resistant to corrosion or causes leakage, it will pose a safety risk.
When used in consumer products or bio-related fields, it is necessary to pay attention to its biosafety. Although the available information does not show that the substance has typical biotoxic groups, in-depth toxicological studies are still needed. For example, cytotoxicity tests are carried out to investigate its effects on the growth and metabolism of different cell lines; animal experiments are carried out to evaluate acute, subchronic and chronic toxicity under oral and transdermal exposure routes, including potential effects on organ function, reproductive development, etc. At the same time, it is also necessary to study its metabolic pathways and degradation products in organisms, because some degradation products are toxic or higher than parent compounds.
In addition, environmental safety cannot be ignored. If the substance enters the environment, its migration and transformation laws in water, soil and atmosphere need to be investigated. Due to its sulfonate structure, it may have certain solubility in water and may have potential effects on aquatic ecosystems. It is necessary to evaluate its toxic effects on aquatic organisms such as fish and algae, as well as its degradability and persistence in the environment.

The method of preparing disodium 2,2 '- [biphenyl-4,4' -diyl di (E) ethylene-2,1-diyl] diphenyl sulfonate is quite complicated. First of all, you need to prepare biphenyl, halogenated styrene, sulfonation reagents and bases and other raw materials.
First take biphenyl and couple it with halogenated styrene with a specific catalyst. This process requires control of the reaction temperature, duration and the proportion of raw materials. The temperature should be in a moderate range, and the duration must also be accurate. Disproportion affects the yield. After the reaction, an intermediate product containing biphenyl-4,4 '-diyl di (E) ethylene-2,1-diyl is obtained.
Next, the intermediate product is sulfonated with a sulfonating agent. Choose a suitable sulfonating agent, such as concentrated sulfuric acid or fuming sulfuric acid, and react under appropriate conditions. During sulfonation, temperature, time and the amount of sulfonating agent are all critical. If the temperature is too high or the time is too long, it may cause excessive sulfonation and damage the purity of the product.
After sulfonation, the product reacts with the base to form a salt to obtain disodium 2,2 '- [biphenyl-4,4' -diyl di (E) ethylene-2,1-diyl] dibenzene sulfonate. The commonly used base is sodium hydroxide, etc. The reaction conditions for salt formation also need to be fine-tuned.
The reaction is over, and the product is separated and purified. Crystallization, chromatographic separation and other methods can be recovered to remove impurities and obtain high-purity products.
The whole production process, the reaction conditions of each step need to be strictly controlled, and the quality of raw materials and operating specifications are also required. Only in this way can high-quality disodium 2,2 '- [biphenyl-4,4' -diyl di (E) ethylene-2,1-diyl] diphenyl sulfonate be obtained.

This is disodium 2,2 '- [biphenyl-4,4' -diyl bis (trans) ethylene-2,1-diyl] diphenyl sulfonate, which has significant differences in application in different fields.
In the field of dyeing and weaving, this material is often used as a high-efficiency dispersant. Because of its excellent hydrophilicity and dispersion properties, the dye can be evenly dispersed in the dye solution, effectively preventing the dye from accumulating and precipitating. In this way, the fabric can be dyed with uniform color and bright effect, which greatly improves the dyeing quality. And it can enhance the combination of dye and fabric fibers, so that the dyeing fastness is significantly enhanced, and the dyed fabric is not easy to fade after many washes.
In the paint industry, this substance can be used as a dispersion aid. In the preparation process of the coating, the pigment particles can be effectively dispersed, which greatly improves the stability of the coating system. This can avoid pigment sedimentation, ensure good leveling during coating application, uniform and smooth coating, and greatly improve the decorative and protective properties of the coating.
In the paper industry, it can be used as an auxiliary for paper sizing. It can improve the dispersion of the sizing agent, so that it is more evenly distributed on the surface of the paper, enhancing the water resistance of the paper. At the same time, it can also improve the physical strength of the paper, such as tensile strength and burst resistance, and then improve the quality of the paper.
In the field of detergents, this substance can be used as a cleaning aid. Its dispersion and anti-redeposition properties are outstanding, which can effectively prevent dirt from adhering to clothes again, and improve the detergent decontamination ability. Moreover, it has good compatibility with other surfactants, which can synergize and optimize the comprehensive performance of detergents.
In summary, disodium 2,2 '- [biphenyl-4,4' -diyl bis (trans) ethylene-2,1-diyl] diphenyl sulfonate plays a key role in various fields due to its unique properties. Due to the different needs and mechanisms of action in each field, its application effect and emphasis are also different.
