The production method and manufacturing process of surfactants, and what are the commonly used raw materials ammonium lauryl sulfate

Must read

Surfactant is a type of compound that can create a directional setup externally of an option and significantly reduce the surface tension. They are commonly used in chemical manufacturing and can be made use of as emulsifiers, moistening representatives, frothing representatives, defoaming agents, dispersants, and so on. This write-up will present numerous typical surfactant production techniques.


1. Sulfonation approach

Sulfonation is the primary technique for creating anionic surfactants. Typically utilized basic materials consist of oil items and natural oils. Sulfonation responses are generally executed at high temperatures. Commonly made use of sulfonating agents include sulfuric acid, chlorosulfonic acid, and sulfur dioxide. The product of the sulfonation reaction is sulfonate, which has excellent wetting and emulsifying homes.

2. Etherification approach

The etherification approach is among the methods for generating nonionic surfactants. Typically utilized basic materials include ethylene oxide, propylene oxide, and alcohol. The etherification response is the enhancement of alcohol to ethylene oxide or propylene oxide in the visibility of an alkaline stimulant to produce polyoxyethylene ether or polypropylene ether. This kind of surfactant has excellent emulsification, diffusion, and tough water resistance.

3. Esterification method

Esterification is one of the methods for creating anionic and nonionic surfactants. Commonly used basic materials include fatty acids, alcohols, and acid anhydrides. The esterification response is to respond fatty acids with alcohols in the existence of acidic catalysts to develop fatty acid esters, which are then included with ethylene oxide to create polyoxyethylene fat esters. This sort of surfactant has great wetting and emulsifying buildings.

4. Amination method

The amination approach is among the approaches for creating cationic surfactants. Frequently utilized resources consist of amines and acids. Amination response is to respond amine with acid to develop amine salt in the existence of an acidic stimulant and then react with halogenated hydrocarbon to develop a quaternary ammonium salt cationic surfactant. This type of surfactant has excellent bactericidal and antistatic buildings.

The above are numerous typical surfactant manufacturing approaches. Various methods appropriate for various basic materials and product kinds. Throughout the production process, it is required to choose an appropriate manufacturing technique based on the efficiency needs of the item and the features of the raw products. At the very same time, we additionally need to take note of issues such as safety, environmental protection, and quality control during the manufacturing procedure to guarantee item top quality and production sustainability.
