Anionic surfactant is a kind of surfactant with the largest variety, the largest dosage and the most extensive application, accounting for about 40% of the total surfactant. Anionic surfactant is mainly used as detergent, in addition, it is also widely used in textile, petrochemical, mineral processing, papermaking and other industries as emulsifier, diffusion agent, gel agent, penetrant, detergent, foaming agent. Anionic surfactants can be divided into carboxylate type, sulfonate type, sulfate type, phosphate type, etc.The main products are linear alkyl benzene sulfonate, linear alkane sulfonate, olefin sulfonate, fatty alcohol sulfate, aliphatic alcohol ether sulfate, etc. The research focus in the field of surfactants - alkyl diphenyl ether sodium disulfonate synthesis technology by the United States and France has finally broken the monopoly situation.
