Procedure

174.4 parts of a 50% NaOH solution are dissolved in 373.8 parts of deionized water to make a 16% solution. The solution is cooled to room temperature. 452 parts of 2-acrylamido-2-methylpropane sulfonic acid monomer (AMPS) are added to the solution at between about 25 and about 30° C. After the AMPS has fully dissolved, the solution is cooled to 20° C. and the pH is adjusted to 9.1. The solvent is removed to yield sodium 2-acrylamido-2-methylpropane sulfonate monomer.

Workup

  1. dissolutionAfter the AMPS has fully dissolved
  2. temperaturethe solution is cooled to 20° C.
  3. customThe solvent is removed
