Yield: 91.2%

Reaction Conditions:

in water at 90; for 16 h;

Steps:

1 Synthesis of (±) -2,3-dihydroxypropyl trimethylammonium chloride
0.00 g of (±)-3-chloro-1,2-propanediol (0.452 mol), 178.00 g of a 30% aqueous solution of trimethylamine (0.904 mol) and 50 mL of water were added to a 500 mL vial.Then, the temperature was raised to 90 ° C, and the mixture was stirred for 16 hours to complete the reaction of the raw material 3-chloro-1,2-propanediol.The temperature was lowered to 20 ° C, and the reaction mixture was washed three times with ethyl acetate (100 mL×3), and the aqueous solution was collected and concentrated to dryness to give a white solid (70.00 g), yield 91.2%, HPLC purity 93.40%.
