| titleOfInvention | Amphiphilic water-based diionic amide surfactant and preparation method thereof |
| abstract | The invention belongs to the field of surfactant preparation, and particularly relates to an amphiphilic water-based diionic amide surfactant containing carboxyl and amino and a preparation method thereof, wherein the structural general formula of the surfactant is as follows: (ii) a Wherein R is or; the preparation method comprises the following steps: dissolving diamine in tetrahydrofuran, stirring, dissolving di-tert-butyl dicarbonate in tetrahydrofuran, adding the di-tert-butyl dicarbonate solution into the diamine solution, adding dichloromethane into the product obtained by column chromatography separation for dissolving, adding decyl succinic anhydride, stirring, adding hydrochloric acid into the product obtained by second column chromatography separation, and stirring. The invention can regulate the pH value of the surfactant by introducing carboxyl and amino, improves the biodegradability of the surfactant and can reduce the surface tension of an oil-water interface. |
