Embodiment Construction
[0012] Add 22g (0.1mol) of p-nonylphenol, 4.4g (0.11mol) of sodium hydroxide and 50ml of isopropanol into a three-necked flask, heat to 50°C-60°C, stir with nitrogen for 1-2h, and slowly add 21g ( 0.11mol) of 3-chloro-2-hydroxypropyltrimethylammonium chloride, stirred for 2-3 hours, cooled to room temperature, filtered to remove inorganic matter, rinsed with isopropanol for 2-3 times, combined with the filtrate, and distilled The solvent was removed, recrystallized with acetone, and vacuum-dried to obtain NPQT as a light yellow solid powder.
[0013] Add 50ml of anhydrous ethylene glycol dimethyl ether and 7.5g (0.02mol) NPQT into the three-necked flask, cool down to below 10°C, slowly add 0.22mol60% NaH in several times (wash with anhydrous ether to remove oil), When the bubbles completely disappear, add 0.12mol dibromomethane ethylene glycol dimethyl ether solution, stir at room temperature for 2-3 hours, monitor the reaction process with HPLC, after the reaction is complete...
