Embodiment 1
[0024] First, dissolve 100mmol of erucamide propyl dimethyl tertiary amine in 100mL of ethanol, then add 150mmol of hydrogen chloride into the round bottom flask, and stir at room temperature for 5min to completely dissolve the hydrochloric acid into the solution. Then, 150 mmol of epichlorohydrin was added into the flask, and the temperature was raised to 60° C. for 6 hours of reaction. After the reaction was completed, ethanol and epichlorohydrin were removed by rotary evaporation, and finally a light yellow viscous paste was obtained, which was placed in a dry bottle for later use, and was recorded as HYZ-22, with a yield of 92%.
[0025] Dissolve 100mmol of HYZ-22 in 50mL of ethanol, and dissolve 150mol of sodium p-aminobenzenesulfonate in 100ml of deionized water, gradually add the HZT-22 solution dropwise into the solution of sodium p-sulfanil React at 90°C for 24h. After the reaction, the solvent was removed by rotary evaporation to obtain a yellow viscous paste. Afte...
Embodiment 2
[0028] First, dissolve 100mmol of dodecyl dimethyl tertiary amine in 100mL of ethanol, then add 100mmol of hydrogen chloride into the round bottom flask, and stir at room temperature for 5min to completely dissolve the hydrochloric acid into the solution. Next, 100 mmol of epichlorohydrin was added into the flask, and the temperature was raised to 50° C., and reacted for 6 hours. After the reaction was completed, ethanol and epichlorohydrin were removed by rotary evaporation, and a light yellow viscous paste was finally obtained, which was placed in a dry bottle for later use, and was recorded as HYZ-12, with a yield of 85%.
[0029] Dissolve 100mmol of HYZ-12 in 50mL of ethanol, and dissolve 100mol of sodium p-aminobenzenesulfonate in 100ml of deionized water, gradually add the HZT-12 solution dropwise into the solution of sodium p-sulfanil React at 90°C for 24h. After the reaction, the solvent was removed by rotary evaporation to obtain a yellow viscous paste. After adding...
Embodiment 3
[0032] First, dissolve 100mmol of hexadecyldimethyl tertiary amine in 100mL of ethanol, then add 120mmol of hydrogen chloride into the round bottom flask, and stir at room temperature for 5min to completely dissolve the hydrochloric acid into the solution. Then, 120 mmol of epichlorohydrin was added into the flask, and the temperature was raised to 55° C., and reacted for 6 h. After the reaction was completed, ethanol and epichlorohydrin were removed by rotary evaporation, and a light yellow viscous paste was finally obtained, which was placed in a dry bottle for later use, and was recorded as HYZ-16, with a yield of 88%.
[0033] Dissolve 100mmol of HYZ-16 in 50mL of ethanol, and dissolve 120mol of sodium p-aminobenzenesulfonate in 100ml of deionized water, gradually add the HZT-16 solution dropwise into the solution of sodium p-sulfanil React at 90°C for 24h. After the reaction, the solvent was removed by rotary evaporation to obtain a yellow viscous paste. After adding ex...
