Oil-based chemicals are derived from natural animal and vegetable oils through processes such as hydrolysis, fractionation, transesterification, and hydrogenation, yielding products like fatty acids, fatty alcohols, and glycerol. These substances serve as crucial starting materials for the production of surfactants—for instance, fatty alcohols react with ethylene oxide to form...AEOSeries of nonionic surfactants, which themselves are also important formulation components.
The training session will delve into the applications of surfactants through a wide range of cross-industry case studies.
- Daily Chemical Industry:This is the most traditional application area of surfactants. For instance, in laundry detergents, anionic surfactants (such asLAS,AES) Provides the primary cleaning power, nonionic surfactants (such asAEO-9) It enhances the emulsifying ability for polar oils such as sebum. In shampoos, amphoteric ionic surfactants (such as betaine) Used in combination with primary surfactants to reduce irritation, thicken, and stabilize foam.
- Food Industry:Sucrose fatty acid ester, as a safe non-ionic surfactant, is used as an emulsifier and dispersant. It is widely applied in ice cream, chocolate, and margarine to improve texture and stability.
- Petroleum Industry:Biosurfactants (such as rhamnolipids) and chemical surfactants are used in tertiary oil recovery to reduce the interfacial tension between oil and water, thereby extracting residual crude oil trapped in rock pores that is difficult to recover."Drive away"Emerging, significantly enhancing crude oil recovery rates.
- Materials and Coatings:Surfactants are used as emulsifiers in emulsion polymerization to prepare acrylates and styrene.-Polymer emulsions such as butadiene are used in fields like coatings and adhesives.
- Textile Industry:In the processes of spinning, weaving, printing and dyeing, and finishing, surfactants serve as wetting agents, penetrants, scouring agents, and softeners, ensuring smooth operations and imparting excellent properties to the fabrics.
Through such systematic communication, practitioners can deeply understand how to reverse-engineer and design the most suitable fatty chemical and surfactant formulations and application processes based on the performance requirements of downstream products.
