摘要： 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.
