[0035] Example 1
[0036] The preparation method of 3-p-nonylphenoxy-2-hydroxypropyltrimethylammonium halide includes the following steps:
[0037] (1) Synthesis of p-nonylphenyl glycidyl ether
[0038] Add 0.1 mol (about 22g) of p-nonylphenol, 50ml of toluene, and about 1g of tetrabutylammonium bromide into a 250ml four-necked flask and stir to dissolve it; weigh out 0.1mol (4.0g) of NaOH and dissolve in about 4ml of distilled water Into a four-necked flask, stir for 3 minutes and then heat with warm water. When the temperature rises to 50℃±1℃, add 0.2 mol (about 16ml) of epichlorohydrin dropwise, add it in 15min to 16min, and then heat up to 70 ℃±1℃, 5,000 rpm, vigorously stir the reaction for 4 hours; after the reaction is completed, the product solution is slightly cooled and washed with 50 ℃ warm water in a separatory funnel for 2 to 3 times, then the upper organic phase is taken out and transferred to a conical flask , Add 5g of anhydrous sodium sulfate and dry overnight; th...

[0043] Example 2
[0044] The preparation method of 3-p-nonylphenoxy-2-hydroxypropyltrimethylammonium halide includes the following steps:
[0045] (1) Synthesis of p-nonylphenyl glycidyl ether
[0046] Add p-nonylphenol, toluene, and tetrabutylammonium bromide into a four-necked flask, stir to dissolve it; weigh out NaOH, dissolve it in distilled water, drop it into the four-necked flask, stir for 2min and then heat with warm water. After the temperature is raised to 50℃±1℃, add epichlorohydrin dropwise, 15min~16min complete, then heat up to 70℃±1℃, stir for 5h at 4000 rpm; after the reaction, cool the product solution and use 50℃ Wash 3 times with warm water in a separatory funnel, then take out the upper organic phase, transfer to a conical flask, add anhydrous sodium sulfate of 1 / 10 of the volume weight of the organic phase, and dry overnight; then transfer the liquid to a pear-shaped flask, Use a rotary evaporator to distill toluene and epichlorohydrin to obtain colorless p-n...

[0053] Example 3
[0054] The preparation method of 3-p-nonylphenoxy-2-hydroxypropyltrimethylammonium halide includes the following steps:
[0055] (1) Synthesis of p-nonylphenyl glycidyl ether
[0056] Add p-nonylphenol, toluene, and tetrabutylammonium bromide into a four-neck flask, stir to dissolve it; weigh out NaOH, dissolve it in distilled water, drop it into the four-neck flask, stir for 5 minutes and then heat it with warm water. After raising to 50℃±1℃, add epichlorohydrin dropwise, 15min~16min after adding, then heat to 70℃±1℃, stirring at 4500 rpm for 4.5h; after the reaction is completed, the product solution is cooled and used at 50℃ Wash the upper organic phase in a separatory funnel twice, then take out the upper organic phase, transfer to a conical flask, add anhydrous sodium sulfate of 1 / 9 of the volume weight of the organic phase, and dry overnight; then transfer the liquid to a pear-shaped flask , Use a rotary evaporator to distill toluene and epichlorohydrin to...
