Sodium Dodecylbenzenesulphonate CAS 25155-30-0 is the commonly used anionic surfactant.

    Sodium Dodecylbenzenesulfonate (SDBS) is a surfactant commonly used in detergents, emulsifiers, foaming agents and other fields. This article will elaborate on the nature, preparation and application of SDBS.

    I. Properties of SDBS

    SDBS is a white or light yellow powder with molecular formula C18H29NaO3S and molecular weight 348.48. It is an anionic surfactant with good surface activity and wettability, and can reduce the surface tension of liquid. In addition, SDBS has good emulsification and foam properties, which can stabilize the particles and bubbles in the liquid.

    Second, the preparation of SDBS

    There are various methods for the preparation of SDBS, one of the common methods is the preparation of benzenesulfonic acid and dodecylbenzene reaction. Specific steps are as follows:

    • 1. Dissolve benzenesulfonic acid in dilute sulfuric acid and heat to 90°C.
    • 2. Dissolve dodecylbenzene in sodium hydroxide solution and heat to 90°C.
    • 3. Mix the two solutions together slowly and react for 4 hours.
    • 4. Adjust the pH value to 8-9 with sodium hydroxide solution and filter to get SDBS.

    C. Application of SDBS

    1.  Detergent: SDBS is an excellent detergent component, which can effectively remove oil and stains and make clothes cleaner.
    2.  Emulsifier: SDBS can stabilize the oil-water mixture and is often used in the preparation of emulsifiers.
    3.  Foam agent: SDBS has good foam performance and can play the role of foam stabilizer in detergents, shampoos and other products.
    4.  Other applications: SDBS can also be used in dyes, coatings, paper and other fields, with good dispersibility and stability.

    IV. Safety of SDBS

    SDBS need to pay attention to safety during use, avoid contact with skin and eyes. In case of inadvertent contact, it should be rinsed immediately with plenty of water and treated by a doctor. In addition, SDBS also needs to be protected from moisture, sunlight and fire during storage and transportation.

    In conclusion, SDBS is an important surfactant with wide application prospects. It needs to pay attention to safety and follow relevant regulations and standards in the process of use to ensure its safe and efficient application.

    Production and synthesis Sodium dodecylbenzene sulfonate:

    1. Alkylbenzene sulfonation: First, benzene is reacted with an alkylating agent such as chloroalkanes or olefins through an alkylation reaction to produce alkylbenzene. The commonly used alkylating agent is dodecylbenzene (Dodecylbenzene). The alkylation reaction usually uses a Lewis acid catalyst, such as aluminum chloride (AlCl<sub>3</sub>) or hydrogen fluoride (HF).
    2. Sulfonation: Then, the alkylbenzene is subjected to a sulfonation reaction with a sulfonating agent (such as fuming sulfuric acid, sulfur trioxide) to introduce the sulfonic acid group (-SO<sub>3</sub>H) into the benzene ring to produce alkylbenzene sulfonic acid.
    3. Neutralization: Finally, the alkylbenzene sulfonic acid is neutralized with an alkaline substance such as sodium hydroxide (NaOH) or sodium carbonate (Na<sub>2</sub>CO<sub>3</sub>) to produce sodium dodecylbenzene sulfonate (SDBS).
