About TEA dodecylbenzenesulfonate:

Solubility: dodecyl benzene sulfonate is easily soluble in water, and its aqueous solution has a low surface tension, showing good wettability and permeability. The solubility is related to temperature, water quality and the type of sulfonate, and the solubility in alkaline water is generally greater than that in acidic water.

Surface activity: This property makes it widely used in many fields, such as detergents, cosmetics, pesticides and so on.

Chemical stability: Dodecylbenzene sulfonate has a certain chemical stability, which makes it difficult to hydrolyze, oxidate, and perform other reactions. Under normal conditions, its aqueous solution can maintain stability for a long time.

Decontamination ability: Due to its low surface tension and good wettability, dodecyl benzene sulfonate has a strong decontamination ability. In detergents and other products, dodecyl benzene sulfonate is the main component that can effectively remove stains and oil stains.

Biocompatibility: dodecyl benzene sulfonate is compatible with organisms, but long-term use may have a certain impact on the environment and organisms. Therefore, use should follow the relevant laws, regulations, and safety provisions.

Synthesis method: The synthesis of dodecyl benzene sulfonate is usually obtained by sulfonating long-chain alkyl benzene with concentrated sulfuric acid. In the synthesis process, attention should be paid to controlling the reaction temperature, concentration, catalyst and other conditions to ensure the purity and yield of the product.

Molecular structure: The molecular structure of dodecyl benzene sulfonate consists of alkyl benzene and sulfonic acid groups, in which the alkyl benzene part provides hydrophobicity. In contrast, the sulfonic acid group provides hydrophilicity. This special molecular structure allows it to form a double electric layer in an aqueous solution, thereby reducing surface tension.

Environmental impact: Regarding environmental protection, dodecyl benzene sulfonate may have a certain impact on the environment during production and use, such as generating wastewater and gas. Therefore, it is necessary to take effective measures to reduce environmental pollution.

Compatibility: Dodecylbenzene sulfonate is compatible and can be mixed with other surfactants, additives, etc.; it is often combined with other ingredients when preparing various detergents, cosmetics, pesticides and other products.

Safety: Dodecylbenzene sulfonate is safe under normal conditions of use. However, if used improperly or consumed in large quantities, it may have certain effects on human health. Therefore, product instructions and safety guidelines should be followed to ensure personnel safety.

Production Method of TEA dodecylbenzenesulfonate:

Raw material preparation

Dodecyl benzene sulfonate includes dodecyl benzene, concentrated sulfuric acid, catalyst, etc. Among them, dodecyl benzene provides a hydrophobic part; Concentrated sulfuric acid, as a sulfonation agent, provides a hydrophilic part. The catalyst can accelerate the reaction process and improve the purity and stability of the product.

Production steps

Sulfonation reaction: dodecyl benzene is sulfonated with concentrated sulfuric acid at a certain temperature and pressure to produce dodecyl benzene sulfonic acid. The sulfonation reaction is the key step, which needs to control the reaction temperature, pressure, concentration and other parameters to ensure the purity and yield of the product.

Separation and purification: After the reaction, the reaction liquid is cooled and diluted to precipitate the dodecyl benzene sulfonate from the reaction liquid. The crude dodecyl benzene sulfonate was obtained by filtration, washing and drying.

Refining: To improve the purity of dodecyl benzene sulfonate, further refining treatment is required. Recrystallization, ion exchange and other methods are usually used to remove impurities and by-products and improve the purity of products.

Drying: The resulting dodecyl benzene sulfonate is dried to remove residual moisture and other volatile impurities. When drying, it is necessary to control temperature and humidity to avoid adverse phenomena such as caking or degradation of products.
