[0045] (1) Preparation of monoquaternary ammonium salt
[0046] Add 15 parts of water into a reactor equipped with a stirrer, a thermometer and a constant pressure dropping funnel, add 50 parts of concentrated hydrochloric acid with a mass fraction of 37% while stirring, and then add 78.5 parts of N, N-dimethyl- Octylamine, after stirring at room temperature for 30 minutes, heat up to 40°C, add 47 parts of epichlorohydrin dropwise, adjust the dropping rate to keep the reaction temperature at 40°C, after the addition, raise the temperature to 70°C, react for 3 hours, and then cool down to 40°C, add dropwise 60 parts of NaOH aqueous solution with a mass fraction of 33.3% while stirring, keep at 40°C for 30 minutes, then cool and discharge to obtain a monoquaternary ammonium salt solution (solid content is 50%);
[0047] (2) Preparation of Gemini cationic surfactant
