【Preparation of TAPSO】A mixture of 242.28 grams (2 moles) of tris (hydroxymethyl) aminomethane, 500 milliliters of water, and 196.5 grams (1 mole) of sodium 3-chloro-2-hydroxypropylsulfonate was placed in a 1 liter 2-neck flask with a stirrer and condenser. Stir the mixture vigorously under reflux for 3 hours. After cooling to 25 ℃, allow the solution to pass through a Dowex50, hydrogen form cation exchange resin column to remove sodium cations and form free acids. The eluent from the column evaporates into heavy oil under vacuum. After dilution with alcohol, the product crystallizes from the solution, is filtered, washed with alcohol, and dried. Obtain 160 grams of white product N-tris (hydroxymethyl) methylene-2-hydroxypropanesulfonic acid.
