A process for producing a surfactant having two head groups and a single tail group per molecule, including steps of: producing a compound of Formula (1) from ethanol and carbon disulfide; producing a compound of Formula (2) from a carboxylic acid and bromine; producing a compound of Formula (3) from the compound of Formula (2) and methanol; producing a compound of Formula (4) from the compound of Formula (1) and the compound of Formula (3); and producing a compound of Formula (5) from the compound of Formula (4) by a direct oxidation process or by a peracid oxidation process. The surfactant produced by the process has lower critical micelle concentration and enables a lower surface tension of a liquid as compared with prior surfactants with two head groups per molecule, thereby enabling the amount of surfactant required and thus the cost to be substantially reduced.

The disclosure relates to the technical field of sterilizing and disinfecting materials, and specifically relates to an α-substituted phenyl structure-containing compound, a preparation method thereof, and a disinfectant. The α-substituted phenyl structure-containing compound according to the disclosure could achieve a bactericidal effect by promoting the coagulation and denaturation of the protein of pathogenic microorganisms. In particular, it has a good killing effect on pathogenic bacteria such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Bacillus subtilis var. niger spores. Besides, it has no corrosive effect on metals, no irritating odor, good water solubility, and is green and environmentally friendly. Therefore, it could be widely used in various industries as an effective ingredient of a disinfectant.
