| titleOfInvention | Zwitterionic surfactant and preparation method thereof |
| abstract | The invention discloses a zwitterionic surfactant and a preparation method thereof, wherein the zwitterionic surfactant is prepared by the following steps: dropwise adding a quantitative 1-substituted aziridine reactant into a reaction bottle filled with long-chain unsaturated fatty acid to perform a first-step aziridine ring-opening reaction; under the condition of alkalescence, adding a certain amount of 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride aqueous solution into the reactant to carry out second-step quaternization reaction, and finally adding sulfite aqueous solution into the reactant to carry out sulfonation reaction on double bonds to obtain the zwitterionic surfactant, wherein the molecular structural formula of the zwitterionic surfactant is as follows: wherein n is 7-8, and m is 7-11; r 1 -is of |
