| titleOfInvention | Sulfate-based anionic gemini surfactant and preparation method thereof |
| abstract | The application belongs to the technical field of surfactants, and particularly relates to a sulfate-based anionic gemini surfactant and a preparation method thereof. The application discloses a sulfate-based anionic gemini surfactant, which has a structure shown as a formula (I), wherein A is selected from alkyl, substituted alkyl, ether, phenyl or substituted phenyl, R is straight-chain alkyl containing 1-3 carbon atoms, X is methyl or phenyl, n is an integer of 8-16, a is an integer not less than 1, and the sum of a and b is 3. The sulfate-based anionic gemini surfactant has a sulfate-containing hydrophilic chain and a siloxane hydrophobic chain, is excellent in surface activity and strong in wettability, can meet the requirements of temperature resistance, salt resistance and calcium and magnesium resistance, and can effectively perform wetting reversal on rocks. |
