| titleOfInvention | A kind of recrystallization method and preparation method of 2- acrylamide-2-methylpro panesulfonic acids |
| abstract | The present invention provides a kind of recrystallization methods of 2- acrylamide-2-methylpro panesulfonic acids, including：2- acrylamide-2-methylpro panesulfonic acids crude product and carboxylic acid aqueous solution are mixed to get mixture, the mixture is heated, then cools down again, simultaneously drying solid is separated by solid-liquid separation, obtains 2- acrylamide-2-methylpro panesulfonic acid sterlings；Wherein, the carboxylic acid includes C 3 ‑C 9 At least one of aliphatic acid.The present invention also provides a kind of preparation methods of 2- acrylamide-2-methylpro panesulfonic acids, have obtained the higher 2- acrylamide-2-methylpro panesulfonic acids sterling of recrystallization yield. |
