Characteristics and classification of surfactants
Surfactants refer to certain organic compounds that are not only soluble in water or other solvents, but also oriented at the phase interface and can change the properties of the interface I. They gen…
Properties and applications of surfactants
The properties of matter are determined by their molecular structure. Surfactant molecules have an asymmetric amphiphilic structure, that is, the molecular structure of all surfactants contains long n…
Introduction of anionic surfactant alkylbenzene sulfonate TPS
Strictly speaking, soap is also an anionic surfactant, but it has been customarily divided into two categories with synthetic surfactants, so this article will not discuss it. Synthesis problem Alkylb…
