摘要： A method for purifying acrylamide alkyl sulfonic acid comprises: (1) making a material A evenly mixed and contacted with a solvent C, an amount of the material A exceeding a solubility of the material A in the solvent C under the condition where the material A is located, therefore the material A is not completely dissolved by the solvent C; (2) keeping the material A even mixed and contacted with the solvent C for at least 5 minutes; (3) performing a solid-liquid separation to obtain a solid, namely, a purified product B with impurities reduced. In the purifying method according to the invention, the material does not need to be completely dissolved, therefore less solvent is used, and the steps of dissolving the material by increasing temperature, separating out by decreasing temperature or removing the solvent are eliminated, so cost is reduced, efficiency is improved, and operations are simplified.
