| abstract |
The invention relates to a benzenesulphonate anionic gemini surfactant and a preparation method thereof. According to the invention, a basic structure with ethylenediamine as a spacer group is subject to a reaction with sodium parachloro benzenesulfonate, such that an intermediate containing two hydrophilic groups is obtained; and the intermediate is subject to a reaction with long-carbon-chain alkane acyl chloride, such that the benzenesulphonate anionic gemini surfactant is obtained. The surfactant is represented by the chemical structure below, wherein n=10, 12, 14, or 16. |
