Sodium dodecylbenzene sulfonate (SDBS) is a commonly used anionic surfactant with a wide range of industrial and commercial applications. It is a white or light yellow powder or flaky solid, which is difficult to volatilize and easily soluble in water. It forms a translucent solution after dissolving in water. SDBS has stable chemical properties in environments such as alkali, dilute acid, and hard water, and shows slight toxicity. This compound not only plays a role as an emulsifier, flotation agent, and impregnation agent in the chemical and textile industries, but also shows its value in many fields due to its unique physicochemical properties.
The molecular formula of SDBS is C18H29NaO3S and the molecular weight is 348.476. It should be stored in a sealed container in a cool, dry place, away from oxides and alkalis to ensure its stability. The physicochemical properties of SDBS include its hydrophobic parameters, the number of hydrogen bond donors and acceptors, the number of rotatable chemical bonds, etc. These parameters together determine its behavior in aqueous solution and its interaction with other substances.
The excellent properties of SDBS include its cleaning performance, emulsification performance, dispersion performance, and foaming performance. These properties enable SDBS to effectively remove various stains and surface oil stains, disperse water and oil mixtures into uniform emulsions, and as a powerful dispersant, effectively disperse oil-soluble substances into water and stabilize them. In addition, SDBS can produce rich foam and is widely used in washing, flannel, foaming and other fields.
In the chemical industry, SDBS is used as a surfactant with excellent performance for efficient cleaning and stable dispersion. Its molecular structure is hydrophilic and lipophilic, which enables it to effectively remove various stains and surface oil stains. At the same time, SDBS can also disperse water and oil mixtures into uniform emulsions, which are easier to clean. In addition, as a powerful dispersant, it can effectively disperse oil-soluble substances into water and stabilize them. These properties make SDBS widely used in chemical, daily chemical and other industries.
