[0024] Example 1
[0025] Firstly, using decanoic acid and ethylenediamine in a molar ratio of 1:1 as raw materials, adding toluene accounting for 20% of the total weight of the reaction material, stirring and heating to 140°C, reacting at a constant temperature for 4 hours; raising the temperature to 220 under vacuum ℃ as the raw material, continue the reaction for 2h to remove the solvent and water to obtain the imidazoline matrix. Then, using dimethylamine and epichlorohydrin in a molar ratio of 1:2.0 as raw materials, 30% of the total weight of the reaction material was added with ethanol, and the same molar amount of hydrochloric acid as epichlorohydrin was added dropwise to the reaction system, and stirred Raise the temperature to 20℃, react at a constant temperature for 12 hours, remove the solvent and unreacted materials, and obtain N-butyl-N,N-bis(3-chloro-2-hydroxypropyl)butane-1-ammonium salt (intermediate ). Finally, take the imidazoline matrix and the intermediate ...

[0030] Example 2
[0031] First, take lauric acid and hydroxyethylethylenediamine with a molar ratio of 1:2 as raw materials, add 50% of the total weight of the reaction materials with meta-xylene, stir and raise the temperature to 180°C, and react at a constant temperature for 2 hours; under vacuum conditions The temperature was raised to 260°C as the raw material, and the reaction was continued for 6 hours to remove the solvent and water to obtain an imidazoline matrix. Then, using diethylamine and epichlorohydrin in a molar ratio of 1:3.0 as raw materials, 50% of the total weight of the reaction material is added with propanol, and the same molar amount of hydrochloric acid as epichlorohydrin is added dropwise to the reaction system. Stir and raise the temperature to 60°C, react at a constant temperature for 8 hours, remove the solvent and unreacted materials, and obtain N-butyl-N,N-bis(3-chloro-2-hydroxypropyl)butane-1-ammonium salt (middle body). Finally, using the imidazo...

[0036] Example 3
[0037] First, take myristic acid and diethylene triamine with a molar ratio of 1:1.5 as raw materials, add 30% of the total weight of the reaction material o-xylene, stir and raise the temperature to 150°C, and react at a constant temperature for 3 hours; The high temperature reaches 230°C as the raw material, and the reaction is continued for 3 hours to remove the solvent and water to obtain the imidazoline matrix. Then, using dipropylamine and epichlorohydrin in a molar ratio of 1:2.5 as raw materials, 40% of the total weight of the reaction material was added with butanol, and the same molar amount of hydrochloric acid as epichlorohydrin was added dropwise to the reaction system, and stirred Raise the temperature to 30°C, react at a constant temperature for 9 hours, remove the solvent and unreacted materials, and obtain N-butyl-N,N-bis(3-chloro-2-hydroxypropyl)butane-1-ammonium salt (intermediate ). Finally, take the imidazoline matrix and intermediate wit...
