What is the main use of dodecylbenzene sulfonate monoisopropanolamine salt?
Sodium dodecyl benzene sulfonate is an anionic surfactant. Its main uses are many. From the perspective of "Tiangong Kaiwu", the following can be said:
First, it is used for cleaning and decontamination. In the daily life of the people, clothing stains are often disturbing. This agent can disperse and emulsify oil stains and other stains in water, just like the clutch of clouds in "Tiangong Kaiwu", making clothes as clean as ever. Taking cloth stains as an example, the oil stains are arranged in water containing sodium dodecyl benzene sulfonate. The molecules are lipophilic at one end, absorb oil stains, and hydrophilic at the other end, so that the oil stains are separated from the cloth surface, dispersed in water, and removed by rinsing. It is a good decontamination product.
Second, in industrial production, such as textile printing and dyeing industry. Fabric pretreatment needs to remove impurities, and sodium dodecylbenzene sulfonate can help it wash the fabric and improve the printing and dyeing effect. Its function is such as the cooperation of the process in "Tiangong Kaiwu", which makes the subsequent printing and dyeing color more fresh and firm, and ensures the quality of the product.
Third, in the agricultural field, it can be used as a pesticide auxiliary. It can enhance the adhesion and spread of pesticides on the surface of plants and improve the efficacy of pesticides. Just like the rational use of various tools and materials in "Tiangong Kaiwu", this agent helps pesticides to better exert their functions of insecticide and sterilization, reduce the amount of pesticides, and improve crop yield and quality.
Fourth, it can be used as an emulsifier in chemical processes such as emulsion polymerization. To form a stable emulsion of the immiscible oil and water phases, promoting the smooth progress of the polymerization reaction, just like the control of various process links in "Tiangong Kaiwu", ensuring the orderly development of chemical production and the production of polymer products with excellent performance.
What are the characteristics of dodecylbenzene sulfonate monoisopropanolamine salt?
Sodium dodecyl benzene sulfonate is a common anionic surfactant. It has many characteristics, as detailed below:
First, it has excellent decontamination ability. This is because of its molecular structure, there are both lipophilic alkyl chains, which can be attached to oil stains, and hydrophilic sulfonic acid groups, which can be soluble in water. Such an amphiphilic structure allows sodium dodecyl benzene sulfonate to reduce the surface tension of water, making it easier for water to penetrate between oil stains and fabric fibers, peeling oil stains from the surface of fabrics and dispersing them in water to achieve good decontamination effect, so it is widely used in many detergents.
Secondly, it has good emulsifying properties. In the oil-water system, the lipophilic group tends to be in the oil phase, and the hydrophilic group tends to be in the water phase, which can form a stable protective film on the surface of the oil droplets, so that the oil droplets are evenly dispersed in the water to form a stable emulsion. This feature is very important in the fields of cosmetics, pesticides, etc. For example, in emulsion cosmetics, it helps to uniformly mix oil and water phases to improve product stability and performance.
Furthermore, it has good foaming properties. When agitated or shaken, it can prompt air to enter the solution and form a large amount of foam. In some detergents such as shampoos and body washes, the rich foam can enhance the user's cleaning experience, and the foam can carry dirt and assist in cleaning.
In addition, it has high chemical stability. Under normal conditions, it is not easily decomposed by acids, bases, oxidants, etc., and can maintain stable performance over a wide pH range. This makes it effective in products of different formulations and has a wide range of adaptability.
However, sodium dodecylbenzene sulfonate has relatively poor biodegradability. If it is released into the environment in large quantities, it is difficult to be rapidly decomposed by microorganisms, which may cause certain pressure on the environment. And when the concentration is too high, it is irritating to the skin and eyes.
What are the precautions for the use of dodecylbenzene sulfonate monoisopropanolamine salt?
Sodium dodecyl benzene sulfonate is a commonly used anionic surfactant. During its use, there are many things to pay attention to.
First, pay attention to concentration control. Although this agent has good decontamination and emulsification effects, if the concentration is too high, it may cause too much foam, which is not only a waste of the agent, but also has an adverse effect on the subsequent process. If there is too much foam during laundry, it is difficult to rinse. On the contrary, if the concentration is too low, it is difficult to give full play to its effect, and the power of decontamination and oil removal is insufficient. Therefore, the appropriate concentration must be precisely prepared according to the specific use and needs.
Second, pay attention to the impact of water quality. Hard water contains calcium, magnesium ions, etc., which are easy to react with sodium dodecylbenzene sulfonate, forming insoluble precipitation, reducing its activity, and weakening the washing and cleaning effect. Therefore, when using in hard water areas, it may be necessary to use a softener, or choose a formula product that is more suitable for hard water to ensure its effectiveness.
Third, pay attention to the role of the environment. Although this agent is relatively easy to biodegrade, a large amount of discharge may still affect the environment such as water bodies. Therefore, the wastewater after use should be properly treated, following environmental protection requirements, and reducing the harm to the ecological environment.
Fourth, pay attention to the impact on the human body. Although it is safer under normal use, if it comes into direct contact with high-concentration products, it may irritate the skin and eyes. Direct contact should be avoided as much as possible during operation. If it is inadvertently touched, it should be rinsed with a large amount of water immediately and seek medical attention if necessary.
Fifth, storage should also be cautious. It should be stored in a cool, dry and well-ventilated place, away from fire and heat sources, to prevent deterioration and safety accidents. At the same time, it is necessary to prevent it from getting damp, because it may affect its performance and use effect after getting damp.
What are the advantages of dodecylbenzene sulfonate monoisopropanolamine salt compared to other similar products?
Compared with other similar products, dodecylbenzene sulfonate monoisopropanolamide succinate does have many extraordinary things.
First, in terms of decontamination performance, this product is excellent. Its molecular structure is unique and delicate. The lipophilic group and hydrophilic group are well matched, just like a natural pair, which can absorb and wrap oil stains more efficiently, just like a warrior catching a thief quickly and accurately. Once in contact with oil stains, it quickly penetrates into the inside of the stain, disintegrates and disperses it, and strips it from the attachment place. The decontamination ability is far better than that of many similar products. It can be used in cleaning scenes such as clothing and tableware, washing dirt and restoring cleanliness as new.
Second, it has significant advantages in terms of mildness. Many similar products, or due to the characteristics of the ingredients, damage the skin, fabrics, etc., during use. This is not the case with dodecylbenzene sulfonate monoisopropanolamide succinate. It is mild in nature, like a spring breeze, and has little irritation to the skin. Even if people with sensitive skin are frequently exposed, it is not easy to cause discomfort such as allergies. At the same time, the degree of damage to fabric fibers is extremely low. While washing clothes, it can carefully care for the original texture of the fabric, making it long-lasting and supple, and the color is still bright.
Furthermore, its foam performance is commendable. The foam produced by this product is delicate and rich, like fine clouds. This not only adds a wonderful visual and tactile experience to the cleaning process, but more importantly, the rich foam can cover the surface to be cleaned more comprehensively, greatly increasing the contact area with the stain, thus further enhancing the cleaning effect. In addition, its foam stability is good, and it is not easy to dissipate during the cleaning process, ensuring the continuity and stability of the cleaning effect.
In addition, it also has excellent compatibility. Like a friendly and collaborative partner, it can coexist harmoniously with many surfactants, additives and other ingredients. In the compounding system, not only will it not interfere with each other, but it can cooperate with each other to exert the wonderful effect of "1 + 1 > 2", which greatly expands the application range in different fields and product formulations to meet diverse cleaning needs.
What is the production process of dodecylbenzene sulfonate monoisopropanolamine salt?
Dodecyl benzene sulfonic acid monoisopropanolamide sulfosuccinate monoester disodium salt is an important product in fine chemical industry. Its production process is unique and exquisite, just like the skills recorded in "Tiangong Kaiwu", all of which require meticulous operation and exquisite control.
At the beginning of its production, dodecyl benzene sulfonic acid is first taken, which is a key raw material. For example, ancient creations must choose excellent materials. When it meets with monoisopropanolamine in a specific reactor, it is just like the ancient craftsmen who made the two things fit. The two are mixed in a certain proportion, and the temperature and reaction time need to be precisely controlled. Just like the ancient alchemy, if the heat is slightly worse, it will fall short. Usually the temperature is controlled within a certain range, so that the two can fully react to form dodecylbenzene sulfonate monoisopropanolamide. The reaction in this step is like casting a sword in ancient times, patiently waiting for the gold to be quenched in the furnace to just right.
Then, after obtaining dodecylbenzene sulfonate monoisopropanolamide, maleic anhydride is introduced. The reaction process of the two reacts under another condition, and there are many details about this reaction process. The pH of the reaction system, temperature and other factors will affect the quality of the product. For example, in ancient pottery, the atmosphere in the kiln was crucial to the quality of the pottery. After the two react, an intermediate product is obtained.
Finally, the intermediate product is sulfonated with sodium bisulfite. This step is just like the finishing touch. Control the reaction conditions, so that sodium bisulfite and intermediate products fully interact, and finally generate dodecylbenzene sulfonic acid monoisopropanolamide sulfosuccinate monoester disodium salt. The whole process, from the selection of raw materials to the control of each step of the reaction, is like the inheritance of ancient techniques, step by step rigorous, can produce high-quality products, and play its unique role in many industrial fields.
